Xiaoman solar terms orchid ventilation

1, there must be a gentle wind blowing.

Wind can send away dirty air and sultry airflow, and bring fresh air at the same time. Throughout the ages, orchid families have emphasized the importance of ventilation as a height related to the survival of orchids. At present, indoor decoration materials emit a lot of harmful gases, and there is also domestic pollution in the room. It is necessary to open more doors and windows to make the air convection, and set up a ventilator when necessary to ensure the indoor air is fresh, which is the primary condition for raising orchids.

2, there should be sunshine and rain (simulation)

Plants nourished by sunshine and rain can thrive, and elegant orchids cannot do without sunshine and rain. Indoor, it is not enough for orchids to receive light only by part of the sunshine from the window and changing the pot position frequently, so lighting is needed to make up the light. Frequent micro-spraying simulates rain and dew, and sprinkling water on the ground creates a humid environment.

3, pay attention to breathable hydrophobic.

A choose blue pots (tile pots, sweat mud pots, etc.) with good air permeability and hydrophobic performance. )

B choose rough planting materials for cultivation (pond stone, fairy soil, ceramsite, etc. )

Build a blue frame and lift it into the air.

4, timely watering and fertilization.

Because it is cultivated with coarse plants, water is easy to lose, so pay attention to moisturizing and avoid being too dry. It is better to fertilize with long-acting slow-release fertilizer (magic fertilizer, etc.). ), supplemented by foliar fertilization.

5. Insecticide and sterilization

Insecticide and disinfection should be carried out regularly, and prevention should be done at least once a month. We should always pay attention to the growth of orchids, prevent pests and diseases in time, and avoid spreading.

How to raise orchids

"Three-point planting and seven-point cultivation" is the experience of ancient people in cultivating orchids. The quality of conservation is related to whether orchids flourish or not, so it is reasonable for predecessors to attach great importance to this. The following details the maintenance and management methods of orchids.

I. Place

The location of orchids is very important, which directly affects their growth and development. Orchids are generally placed in the open field in spring, summer and autumn (in the open shade in summer) and indoors in winter. It is best to be outdoors in an open and humid place. There should be enough light indoors, preferably facing south. In this way, it is beneficial to orchid growth. It's best to put the basin on a wooden frame or table, not on the ground.

Second, shading

Orchids are mostly semi-negative plants, and most varieties are afraid of direct sunlight and need proper shade. Orchids can get more sunshine in the first half of April to promote their growth. Appropriate shade should be provided after the end of April. Erect leaf varieties from Xia Lan and Qiu Lan are best placed in the cool south to get more sunshine. Qiu Lan and Chunlan with drooping leaves should be exposed to the sun for two hours every day. Shade early every day from June to September. If a reed curtain is used, a dense curtain or two-layer thin curtain can be used. After 10, the weather turns cold and the sunshine is weak, so the shading of vegetables can be postponed, but attention should still be paid to shading around noon.

Third, rain protection.

Orchids can rain lightly, but we should avoid mildew rain, showers or even rainy days. In the rainy season, it is particularly necessary to do a good job of rain protection. From late June to mid-September, showers are frequent. If it rains for a short time and the rainfall is small, water it more at night to discharge the hot air in the basin, otherwise it will damage the orchid and even rot its roots and die. If the sun shines after the rain, it should be shaded in time to avoid the influence of the rising heat on the growth of orchids.

The rainy season is the stage when orchids grow leaves. If the pot soil is too warm, it will lead to bad growth of leaves or cause diseases. At this time, a small amount of plant ash can be sprinkled to adjust the humidity of the basin soil.

Fourth, water.

The flower proverb says that "dry orchids wet chrysanthemums" has some truth. Generally speaking, orchids are best to be eight points dry and two points wet. If it is too wet, it is easy to make flowers rot and die. The principle of watering should be: water when it is dry, stop when it is wet, and dry when it is suitable. When mastering the details, it is generally necessary to pay attention to watering more during the growing period (the end of May-June), watering less during the germination period (about March-April) and flowering period (about March-April), and watering less or not during the dormant period (winter). If the flowerpot is big and the orchid plant is small, water less; if the potted plant is big, water more. Water more when the climate is hot and dry, and less or no water when it is cold and humid (such as rainy season). If the roots of orchids newly dug from the mountains are sparse or broken, they should be watered less to make the soil dry, so as to avoid root rot and be conducive to pumping new leaves.

As the ancients said, the experience of "dry in autumn and not wet in winter" well summarized how Chunlan and Xia Lan watered. But in some areas in the north, orchids are not too dry because the climate is too dry in winter and early spring.

Watering time: it is advisable to water orchid leaves after sunset in summer and autumn, so that they can be dried before nightfall, or watered in the morning; It is best to water before and after sunrise in winter and spring. It is not allowed to irrigate with cold water suddenly after the sun burns, so as not to lower the soil temperature, affect the water absorption of roots and interfere with the physiological balance. The amount of watering should not be too large to inhibit the occurrence of diseases.

Watering method: water should be poured from the pot, not into the bud, so as not to cause rot.

The predecessors had great experience in watering orchids. For example, Zhao Yu put forward different watering methods according to the 24 solar terms in the Dumen Lanyi Ji, and the excerpts are as follows for your reference. However, we should pay attention to two points: first, Dumen Lanyi is based on the climate of Beijing; Second, the month in the article refers to the lunar calendar rather than the Gregorian calendar. For example, "the first month" is actually February in the Gregorian calendar.

1, beginning of spring, it rains, Chunlan has flowers, the soil should not be too dry, and it is slightly wet along the basin; Don't water the Qiu Lan Basin if it hasn't been dried to the end.

2, Jing Zhe, when the Chunlan basin is half dry (above the ground), it can be watered and wet, but it should not be too much. Qiu Lan is the same as before.

3, the vernal equinox, Chunlan has faded, avoid dampness, and moisten the basin when it is half dry.

4, Qingming, Grain Rain, don't let the pot soil be too dry, water it every five days.

5, long summer, LAN began to leave home, should be watered once.

6, Xiaoman, the pot soil can not be too dry and too wet, the spots on the leaves are too wet, and the dead tips of the new buds are too dry. Water one liter (about dry teacups) every four days to make the soil moist from bottom to top.

7, mango, dry climate, be careful not to be too wet is more appropriate.

During the summer solstice, the soil in the basin should not be too dry. In case of heavy rain, you can only endure it for one day. If it rains, the basin should be moved to a ventilated place.
