What soil does Chunlan use?

Question 1: What kind of soil should be used to cultivate orchids? It should be loose and ventilated, with good ventilation, proper fertilization and no hidden pests and diseases.

(1) The best formula of culture soil is: 4 parts of yellow sand, 4 parts of sawdust and 2 parts of river sand; If it is yellow loam, there is a river sand, a sawdust and a yellow loam. They are all completely mixed. The pH value of the prepared culture soil should be 6.5-6.8, which is loose and breathable, with good water retention and permeability and comprehensive nutrition. River sand and sawdust are used to conduct water and breathe. Wood chips are decomposed by bacteria, which can slowly release nitrogen, phosphorus and potassium. Yellow loam also contains a variety of trace elements. After years of observation, this formula is very suitable for the growth of orchids. It is especially suitable for domestication and cultivation of wild orchids, Cymbidium hybridum and Cymbidium hybridum, and is also an ideal choice for Cymbidium hybridum and Cymbidium hybridum, with significantly improved flowering rate and stress resistance.

(2) Bamboo root mud. Refers to the soil at the roots of bamboo forests planted for many years. This kind of soil has loose structure and good drainage, but it is not very fertile. Because of the appearance of bamboo whips and roots and the decay of bamboo leaves and stems, it is suitable for orchid growth. The quality of bamboo root mud depends on three factors: first, the original soil quality, which is the predecessor and foundation of bamboo root mud, and sandy loam soil is the best; Secondly, the longer the planting period of bamboo bushes, the more fully the functions of bamboo roots, bamboo leaves and bamboo whips; Thirdly, the distance from the bamboo pile, the closer the soil is to the bamboo pile, the better.

(3) Leveling soil. The chaff is made of green manure (Chinese milk vetch) by harvesting, drying and crushing. The glutinous rice paste is mixed with bamboo root mud or common sandy loam, accumulated and decomposed to obtain glutinous rice paste. The production method is as follows: choose a shelter, remove a layer of chaff from a layer of soil, and pour pig manure water once, so as to pile up layer by layer; After stacking, sprinkle water on the surface to wet it, and then smear it with mud to seal it. Stacking and fermenting for half a year can be used. When in use, other culture soils are mixed in proportion.

(4) Humus soil. Water or fertilize with dead leaves or grass and tall stalks, seal with mud, decompose and sieve. It is best to use seedless grass to fully decompose and kill pests and weeds, otherwise there will be many weeds in the orchid pot in the future.

(5) mountain mud. That is, the mountain soil where wild orchids first grew. It is a mixture of litter and soil for many years. Naturally formed humus soil, rich in humus, is loose and breathable, which is very suitable for orchid growth. In the case of convenient transportation, it is simple and economical to dig a lot of mountain mud to grow orchids, and it is better to domesticate grass. Humus soil under broad-leaved forest, especially under chestnut tree, is an ideal soil for orchids.

(6) Pond sludge. Combined with winter pond and fish pond, mud is dug out, dried and broken into fine particles, which can be used to cultivate all flowers, including orchids.

(7) Field soil. That is, the loose topsoil in the field is selected, mixed with a little sand or a little chaff ash, and then some organic fertilizers such as decomposed compost or fermented bean cakes and rapeseed cakes are added to improve the soil structure and enhance the chemical fertilizer efficiency. Repeatedly turn over the pile and stir evenly, and then sieve. This kind of soil is close to neutral and not as good as humus. Therefore, it is only used reluctantly when there is no suitable humus soil or forest sandy loam, and most of it is used to cultivate rough orchids.

(8) Cow dung soil. The fermented dry cow dung is crushed and ground, mixed with sandy soil or topsoil of field soil, and prepared according to the ratio of 1: 3. In winter, it is best to choose cow dung fed with dry feed, because the dry forage has fine particles, but it is still elastic, plant fiber and contains certain nutrients. This kind of cow dung has soft and fertile soil, which is very suitable for the aerobic of orchid roots. This kind of cow dung soil is often used as a filler to cultivate local orchids in Yilan community of Taiwan Province Province, and the effect is very good.

(9) Black mountain mud, peat, pastoral soil, pine needle soil, moss and bark are used as cultures. Cover the drainage hole at the bottom of the basin with ceramic tiles, then lay a layer of gravel with the thickness of 1/4 basin depth to enhance the air permeability and drainage, and then lay a layer of culture. Plant orchids upright, fill them with culture and cover them with bulbs. The culture should be compacted, 2 cm away from the mouth of the basin, so it is convenient to water. In order to be beautiful and increase the moisturizing power, the surface of the basin can be covered with a layer of broken white stone.

In foreign countries, 5 parts humus soil or humus soil and 1 part Gaza are generally used to cultivate local orchids; Or use 3 parts of peat soil and 1 part of river sand to mix the crushed cow dung, and then use it after thorough mixing. The cultivation substrate of epiphytic orchids is mainly moss and ferns, with a small amount of leaves, small pieces of charcoal and broken cow dung added.

Personally, I think: in fact, there is little difference in which soil to use, and there is no need to be too superstitious about advanced farming soil. I often plant it with 70% broken bricks and 30% peanut shells, which is different from other pots' fairy soil and stone planting. What matters is looseness, breathability and ... >>

Question 2: What is the best soil for growing orchids? How to prepare succulents of orchids? The soil is required to be loose and fertile, with good drainage and acidity, and multi-system mountain mud is often used. However, when planting in the upper basin, there should be more and thicker gaskets at the hole at the bottom of the basin. The gasket should be covered with a layer of broken mud particles. Only after the broken mud particles are wrapped in fine mud can you put the orchids into the pot and then add the mountain mud. This planting method is mainly based on orchid's habit of loving humidity and avoiding water accumulation, so that the drainage is smooth. When using mountain mud, if 1/3 coarse river sand is added, it will be more conducive to drainage and more in line with the growth habits of orchids.

The soil for cultivating orchids in the north is neutral and acidic, containing a lot of humus, which is loose and well drained. Many garden units in the north collect and transport mountain mud from Shaoxing, Zhejiang and other places to cultivate rare varieties. Although it is beneficial to the growth of orchids, the water quality in the north is hard, so it will be replaced in two or three years, and the long-distance transportation price is higher. In recent years, 30% local peat soil, river sand 1% and some organic fertilizers (which need to be stacked for a period of time) have grown well as potted orchids. Saprophytic soil under broad-leaved forest in northern mountainous areas, saprophytic soil composed of deciduous broad-leaved trees and culture soil containing 60% humus can all be used to cultivate orchids.

The epiphytic orchids in potted plants in northern China include Dendrobium, pig excrement beans and dictyophora indusiata. Potted plants can't use soil. Common cultivation materials are sphagnum moss, fern root (water dragon root or purple dustpan root) and a small amount of rotten leaves of broad-leaved trees, small pieces of charcoal and dried cow dung. In addition, broken bricks can also be used to pad the bottom of the pot.

Question 3: What kind of soil is used to raise orchids? It is easier to raise bluestone and fairy soil.

Question 4: What soil does the orchid use? 1. Potted soil requirements: loose and well-drained neutral acidic soil with a large amount of humus is the best, and the PH value is generally around 5.5 to 6.5. In Sichuan, Emei fairy soil and "Hong Xing brand" are mostly used to refine orchid plants, and "bamboo root mud" and humus soil under wet leaf forests in mountainous areas are more popular to cultivate orchids.

2. Location: Orchids can be cultivated outdoors and on balconies in spring, summer and autumn. It is required to choose a place with good ventilation, moist air and no environmental pollution. Just be close to the pond and the river. At least install trees or bamboo forests, install sunshade nets, reduce sunlight exposure and reduce temperature. It is best to put the basin on a wooden frame (or steel frame). If the floor is to be bricked, the balcony at home can also be bricked on a small tin can to increase the humidity.

3, proper shading: orchids are mostly semi-shaded plants, and most varieties are afraid of direct sunlight and need proper shading. Orchids can be opened in the first half of April to get more sunshine and promote their growth. In May, in addition to the sunshine at noon, it can also be basked for 6 hours; It has been cloudy all day since June. After 10, except Zhongyang, it can be fully opened for maintenance. Remember this proverb: "leafy shade is good, and more sunshine is good."

4. Rational fertilization: orchids are vegetarian, and fertilization depends on the selected pot soil and growth. Fertilization can be applied to those who grow luxuriantly and have no diseases, and fertilization or a small amount of fertilization is not suitable for those who grow poorly. A new orchid with incomplete roots needs 1-2 years to be fertilized. Generally, in June and July, when the orchid leaves and buds are about 1.5 cm long, the decomposed liquid fertilizer is applied once every three weeks (the appropriate concentration is about 10%). Don't use chemical fertilizer. If it is not suitable for fertilization in high temperature season, dilute fertilizer should be applied every 2-3 weeks from August to September. Orchids should be fertilized at night and watered in the morning, which is called "backwater".

5. Proper watering: Rainwater and spring water are better for orchids, and tap water or rice washing water should be used overnight. When you pour it, pour it from the edge of the basin, not into the bud. The amount of watering should be determined according to the temperature, the degree of dryness and wetness of the basin soil and the growth of bluegrass. Most of the leaves are watered, and the thin leaves are watered less. From April to May, the new buds haven't grown soil yet, so the soil in the basin should be dry, and the new buds will rot easily if they are too wet. June-September is the growth period of orchid buds, so it is necessary to increase the amount of watering. Water once every morning in sunny days, and it is forbidden to water in the hot sun at noon. To reduce water consumption in autumn, foliar water spraying can be used to keep the basin soil moist, and water consumption can be controlled to keep "80% dry and 20% wet" in winter.

6. Spraying in the evening: orchids are originally grown in a humid air environment, so in the dry season, in addition to shading, they must be sprayed in the evening to increase the air humidity and lower the temperature; You can also water the orchid floor (desktop), and "one cold and one hot" can stimulate the growth of orchids.

7, wind and rain: "February ghost wind" is a normal phenomenon, you can cut off dead branches and broken leaves. Orchids can rain lightly, but avoid mildew rain, heavy rain or continuous rain, otherwise the heart and leaves will rot easily. A small amount of plant ash can be appropriately sprinkled in rainy season.

8. Pruning and picking flowers: In orchid cultivation, you should always cut off dead leaves, broken leaves and diseased leaves. To promote ventilation. For rare orchids, if there are too many flower buds, only strong buds are left, and it is appropriate to have 1-2 flower buds per pot. Chunlan should be picked after half a month of flowering, and rare orchids should be picked after 7 days. The leaf buds in spring thrive and create the beauty of the next year. The last flower of the preface to Sharon was cut 3 cm away from the surface of the basin one week after flowering.

9. Cold and warm: orchids have different cold resistance due to different varieties, different places of origin, so the time to enter the house in winter and the location of indoor display are also different. Hanlan, Qiu Lan and Winter jasmine grow in the south. When the temperature is 5℃, they should enter the room (or close the windows and fences) and try to put them in the sunny place in the south. But in spring and Xia Lan, it has strong cold resistance, and it can only be put indoors at 0℃ and placed in the northeast. Around noon on a windless sunny day, open the window to the south or southeast, and pull the net for ventilation. Qiu Lan is not allowed to open windows on sunny days of 1-2℃. Of course, if there is a greenhouse, you can use electro-optic heating.

10, Disease prevention and insect control: Pot soil should be disinfected (or exposed to the sun) to prevent diseases. Orchids are most prone to white silk disease in rainy and high temperature seasons, and a small amount can be brushed off with wet cloth. The basin volume can be sprayed with Bordeaux mixture or Tobuzine 500-800 times, once every 7- 10 day. Scale insects (commonly known as "blue lice") are the most common pests. During the incubation period, 1% omethoate and 1000 times 25% thiophosphate emulsifiable concentrate were sprayed once a week. It is advisable to treat both the symptoms and the root causes, and the pots and pans should be sparse to increase ventilation and reduce the occurrence of diseases. ...& gt& gt

Question 5: What soil should be used to grow orchids? Orchid roots are fleshy roots, which require loose and fertile soil, good drainage, good air permeability and strong acidity. Preparation: Add 1/3 coarse river sand and 1/3 peat soil into the mountain mud. Improving its soil characteristics is beneficial to the growth of orchids.

Question 6: What soil is better for orchid cultivation? Several aspects that should be paid attention to in orchid cultivation.

Orchid cultivation in China has a long history, and predecessors have accumulated rich experience in orchid cultivation. It is necessary to master the experience of predecessors, absorb its essence and deeply understand: cultivation environment, planting materials, watering, fertilization and pest control. It is the five links of orchid cultivation management.

1. The choice of environment is more important. Whelan mainly grows under shrubs in subtropical forests, and develops the growth habit that orchids like semi-cloudy and semi-sunny, and like moist and ventilated. As long as we master the growth law of orchids and provide or create environmental conditions close to orchids, Cymbidium hybridum is suitable for planting all over the country.

2. Use of plant materials. According to the experience of cultivation in various places, orchids can grow well no matter what plant materials (including soilless culture) are slightly acidic. The problem is that different plant materials should adopt different management methods. It is best to use pottery pots or Yixing pottery pots for flowerpots, because orchids are aerial rooting plants, and the ventilation of flowerpots is very beneficial to the growth of orchids.

3. Rational watering is the key to raising orchids. The water for watering orchids should be clean and slightly acidic, and never water sewage with germs. The method of watering varies from plant to plant. Loose mountain mud contains enough water, and granular soil and rocky volcanic rocks absorb enough water, but there is no water accumulation. After different plants were watered once, the surface of the basin was dry and the plants turned white by about one centimeter. In order to raise the temperature, water can be sprayed on the surface of the basin to increase the water content of the planting materials in the upper water-rich basin, so as to keep the bluegrass and pseudobulbs moist to a certain extent, and then the whole basin can be watered before it is completely dried.

4. Fertilization: On the basis of mastering watering, fertilization is becoming more and more important in order to promote the better growth of Poa pratensis. Organic fertilizer, that is, farm manure, should be diluted every ten days, and other inorganic fertilizers (fertilizers) should be used according to the instructions. Foliage fertilizer can be topdressing outside the roots during the growth period of orchids. Base fertilizer is also very important. When turning over the pots and changing the soil, a proper amount of base fertilizer can be added without touching the orchid roots. Too much fertilizer can easily burn orchid roots and produce black spots. If fertilized properly, it can grow strong seedlings and flowers. Orchid fertilization is generally required to be small, thin and light, and it is really thin and diligent.

5. Pest control: Pests are easy to prevent, but fungal diseases are difficult to treat. If pests such as scale insects are found in bluegrass, they can be sprayed according to the instructions, and it is best to use them together, 2-4 times a year. General bacterial diseases can also be treated as black spots. According to the instructions, fungicides such as chlorhexidine, methyl butyl mustard and chlorothalonil can be used. During the growth period of 15-20 days, regular cross treatment and preventive spraying can be carried out. If Balasi soft rot (rotten coccidiosis) is found, it is an incurable disease of orchids. Once found, it can be removed in time. Therefore, when buying bluegrass, we must pay attention to the fact that we must buy diseased grass with lower price at home, which will affect other valuable bluegrass.

At present, with the increasing demand for orchids at home and abroad, the trend of orchids is quite promising, especially fine products, treasures and rare products. Therefore, the orchid market and the potential market of orchids are very broad, and there is still great room and prospect for the development of orchids. Therefore, we must correctly face, adapt and adapt to this gratifying situation. Fully protect the increasingly depleted orchid resources, master the growth habits of orchids, and make your own bluegrass better.

Question 7: What kind of soil should orchids use? In fact, it doesn't matter much what soil you use. The most important thing is to keep the soil breathable. In this case, some sawdust and ochre can be selected as substrates, but it is best to use humus, that is, the soil after leaf cutting, dried in the sea, or mixed with sawdust and other substrates.

Question 8: What kind of soil humus is used for orchids and the black soil on the top of forest land on the mountain? The soil is slightly acidic and very fertile, which is very suitable for orchid planting. Its disadvantage is that the soil is too fine, and the fine soil will be gradually lost with the erosion of water or rain, which is easy to get sick and needs disinfection before use. Using humus soil alone is easy to attract small insects, so humus soil is generally used in conjunction with other materials. Sandy soil is mainly used to benefit water, keep good drainage in the basin and have certain water storage function. There are many kinds of plant materials on the internet. In order to find suitable planting materials for orchids, we must constantly explore and accumulate experience, and then cultivate high-grade orchids from ordinary grass. Here I tell you that the planting materials of orchids mainly achieve the following points: the planting materials must be breathable, the drainage roof must be determined, and there is a certain water storage function. If the fertilizer is moderate, it must not be reapplied. Just grasp the timing of watering. I hope these are helpful to you! ! !

Question 9: What is the best soil for growing orchids? How to prepare the soil for planting orchids: moist, fertile and rich in humus.

Appropriate blue soil preparation tips are as follows:

Preparation of humus soil from red soil and mountain foundation soil. Humus soil 60%, red soil and mountain foundation soil 20%, humus soil 70%, and red soil 30% mixed with humus soil.

Using field soil and vegetable garden soil to prepare humus soil. 50% is humus soil and 50% is field soil and garden soil. Because both field soil and garden soil are mature soil, the foam is loose and the composition can be aggravated.

Preparation of humus soil and rotten wood soil. Rotten wood mainly refers to rotten oak and rotten wood. Mixed preparation is appropriate. It can also be prepared separately. This preparation must add soil, especially red soil, and can choose field soil, garden soil and mountain soil. Plus the ingredients should be above 20%.

The mixture of humus and sand can be sand or sea sand. River sand, stone sand. Choose coarse sand and use less fine sand. Rotten soil accounts for 60-70% and sandy soil accounts for 40-30%.

Blue soil can be prepared in advance or temporarily, and it is better to prepare in advance than temporarily. When preparing, the materials are mixed together in proportion with an iron pot or barrel pot, and an appropriate amount of water is poured in to moisten the prepared soil, and then the soil is covered in a bag, so that the soil species are fully harmonious and pests in the soil are eliminated.

Question 10: What is the best soil for potted orchids? Four soils for growing orchids:

1, humus soil, red soil and mountain land preparation:

Humus soil 60%, red soil and mountain foundation soil 20%, humus soil 70%, and red soil 30% mixed with humus soil.

2. Preparation of humus soil, field soil and garden soil:

50% is humus soil and 50% is field soil and garden soil. Because both field soil and garden soil are mature soil, the foam is loose and the composition can be aggravated.

3. Preparation of humus soil and rotten wood soil:

Rotten wood mainly refers to rotten oak and rotten wood. Mixed preparation is appropriate. It can also be prepared separately. This preparation must add soil, especially red soil, and can choose field soil, garden soil and mountain soil. Plus the ingredients should be above 20%.

4. Preparation of humus soil and sandy soil:

You can use sand and sea sand. River sand, stone sand. Choose coarse sand and use less fine sand. Rotten soil accounts for 60-70% and sandy soil accounts for 40-30%.
