As the saying goes, all the year round lies in spring, which is the vigorous growth period of flowers blooming. So what? Let me tell you!

First, the managem

As the saying goes, all the year round lies in spring, which is the vigorous growth period of flowers blooming. So what? Let me tell you!

First, the management of orchids in spring pays attention to moistening, penetrating, thinning and applying.

Pay attention to the word "moist", grasp the word "transparent" and pay attention to the word "sparse", but still pay attention to the word "scattered" and pay attention to the cold.

In spring, the water content of plant materials in the basin should be kept moist, and it must be watered thoroughly every time, but remember not to be excessively moist because it needs to be moist. This is a no-no!

When watering, don't water the seedlings to avoid wet buds. When soaking, the water must be one or two centimeters lower than the material level in the pot to avoid soaking buds. This is a no-no!

When fertilizing, it should be proportioned in proportion, and each fertilization should be sufficient to prevent seedling injury and bud injury! Be sure to go back to the water to prevent fertilizer damage!

Sunshine needs to be sufficient, but it still needs to be scattered, especially when the climate is prominent and high temperature, don't be careless! Spring does not come out: pay attention to the cold! In spring, the earth's atmosphere rises and everything begins to wake up and grow. People have a physiological proverb: spring covers autumn without covering it. In spring, we should guard against strong winds and cold spring! But on sunny days and when there is no wind or breeze, you can open the window to get some air.

Second, adjust the sunshine, temperature and ventilation of the blue room to the most suitable state in spring. For the window of the blue room, the sun comes out to open and the sun goes down to close * * * because the place is suitable * * *. Due to the large temperature difference between day and night in early spring, opening the window as soon as the sun comes out in the morning to let in fresh air and warm wind is conducive to the recovery and growth of orchids. Closing the window when the sun goes down can prevent the orchid from being hurt by the cold at night.

Put the orchids that haven't blossomed together, leave her alone, but let them see more sunshine, keep the orchid pot moist, and let her blossom as soon as possible. For orchids that have blossomed, fertilizer should be applied every 7- 15 days after the flowers wither, and the concentration of fertilizer can be slightly higher, because at this time, new roots have grown and new grass has not come out, which will not hurt roots and buds. Once a month in early spring, twice a month in late spring and once a month after late spring, killing insects and preventing orchids. Bluegrass metabolism, yellow leaves should be trimmed in time.

Third, winter goes and spring comes, and Yong Zhen is renewed. After the spring return, all kinds of animals and plants wake up in the spring thunder. At this time, I would like to remind You Lan of the pests in your Orchid Garden, such as scale insects, red spiders and small snails. , should be destroyed anywhere around your orchid garden, including walls, floors, orchids, flower pots, flower stands, roofs, etc.

The vernal equinox is the most vigorous period of germ growth of various plants. The spring buds of orchids cultivated in greenhouse are half long, and the spring buds cultivated outdoors have emerged from the topsoil. This is the best time to kill insects and sterilize, and the immature buds should be prevented from being infected with bacterial diseases and black spot in advance. It is very important to kill insects and sterilize in spring.

The end of the dormancy period of orchids at the vernal equinox is also the best time to change pots and plant them separately.

Common sense of orchid conservation in spring

First, the blue room management

Orchids should appropriately increase the ventilation of orchid rooms with the increase of temperature; For those who have not changed the pot within one year, it is necessary to change the pot quickly. The process of changing pots is also a kind of management, removing rotten roots and leaves, the ramet of this ramet. Orchids need to be cultivated with coarse plant materials with good permeability and drainage, and the coarse plant materials are mostly a mixture of perlite, small stones, fine bark and coarse bark.

Second, fertilization.

During this period, increasing fertilizer supply properly has a great effect on the growth of orchids. However, we should pay attention to implementing the principles of "thin fertilizer and diligent application" and "rather less than more". Fertilization of orchids can be divided into root fertilization and leaf fertilization. It is best to use slow-release fertilizers for root fertilization, such as inorganic fertilizers such as "Haokangduo" and organic fertilizers such as "bone powder phosphate fertilizer" and "orchid organic fertilizer". It is best to choose liquid fertilizer for foliar fertilization, such as "liquid flower treasure" and "multiple roots and multiple buds", to avoid that the solid fertilizer is not fully dissolved and attached to the orchid leaves, resulting in leaf burns. If it is not good for the roots, or if you want to grow more buds, you can choose "multiple roots and multiple buds", dilute them in proportion and then water the roots or spray the leaves. Fertilization is best carried out after watering and leaf drying. Root fertilization is generally once every six months, and foliar fertilizer can be once every five to seven days.

Third, water.

Although the air humidity is relatively high in spring, we should pay attention to watering enough water to strengthen the roots of orchids and keep enough fresh air in the orchid pots. Watering must be thorough every time, to ensure that there is water flowing out from the bottom of the orchid pot, and to wash off the plant substances and air pollutants on the orchid leaves.

The watering time of orchids in spring can be flexibly mastered. The general principle is that the closer the water temperature is to the temperature, the better, and the temperature should be kept above 10 degrees.

The watering interval depends on the plant materials, and the selected plant materials can be once a day or once every two or three days. If the selected plant materials are dense, they can be used once every seven or eight days.

After each watering, it is best to strengthen ventilation and dry the orchid leaves.

Fourth, the prevention and control of pests and diseases.

A year's plan starts with spring. If a thorough prevention can be done during this period, it will have a multiplier effect on the prevention and control of orchid diseases and insect pests throughout the year. Orchid pests and diseases are insects, such as aphids, beetles, red spiders and so on. A genus of fungi, such as carbon maggot and black spot. You can choose "quick killing" in disposable small bottles for killing insects, and "Tobuzin" in bottles made in Japan for sterilization. Make a full spray at different times. Spray thoroughly, not only the leaves and back of orchids, but also the upper and lower parts around the orchid room, orchid racks and orchid pots. On the third day after each spraying, insects, bacteria and residual pesticides must be thoroughly doused with clear water.
