What should be paid attention to in summer: strengthen ventilation, carefully apply water and fertil

Now it's raining and it can't stop at all. Although it's still holding the tail of spring, Xiao Bian thinks that the temperature is as good as summer. When it comes to summer, we have to mention the maintenance of orchids in summer. In this paper, some senior flower friends for orchid summer maintenance and management of some experience and summary, these valuable experience is worth learning.

How to maintain orchids in summer? What orchids should be paid attention to in summer? It is a great test of orchid cultivation skills of flower growers. In the summer of high temperature and high humidity, if the management is not good, it is easy to cause diseases of orchid grass. If it is lighter, the growth of orchid grass is not good. If it is serious, it will cause seedling collapse. Therefore, we should pay attention to the following points in summer

1、 Careful watering: for watering orchid grass, the individual is in line with the principle of not dry, not watering, watering necessary thoroughly. And after watering, strengthen ventilation, as soon as possible to dry the water of the new grass center leaf. When watering, try to avoid higher temperature. It's usually before sunrise in the morning or after ten o'clock in the evening

2、 Ventilation is very important: in hot summer, only by strengthening ventilation can we reduce the temperature of orchid room. Of course, if there is air-conditioning equipment, air conditioning can be used to cool down, but ventilation is indispensable. Otherwise, the long-term enclosed space will make the orchid easily suffer from diseases. In addition, after watering the orchid grass, strengthen the ventilation, and dry the water on the leaf surface as soon as possible, especially the water in the central leaf of the new bud, so as to avoid the occurrence of soft rot as far as possible. I always think that what many orchid elders said, ventilation is the first thing to discuss, is not random nonsense, it's a famous saying accumulated by their long-term orchid cultivation.

3、 Careful fertilization, avoid turning basin: Summer fertilization and turning basin, I think it is a big taboo to raise orchid. Because of the high temperature in summer, Langen is in semi dormant state. If fertilized, the roots will not absorb and transform nutrients. It is easy to cause fertilizer damage to burn the roots. Therefore, fertilization is counterproductive at this time. As for turning the pot, the previous small environment has been destroyed after turning the pot. It takes half to a month or even longer for the roots to adapt to the new environment, that is, to lay the pot, which is prone to stiff buds and fallen seedlings.

4、 Proper shading: in fact, many orchid producing areas of Lanyou can find. In summer, if there is a place where orchid grass grows, there are many leaves on the top of orchid grass. When people walk in, it's very cool. It can be seen that the leaves not only block the sun, but also absorb a lot of heat. Therefore, as our orchid farmers, it is a necessary work to simulate the natural shading way for orchid. Because now we use the sunshade net is black, although it can block the sun, but because it is black, it absorbs more heat. Under the sunlight, the temperature near the sunshade net is higher. Therefore, when individuals shade orchid grass in summer, they should use several layers of sunshade net with a certain distance between them. In order to achieve the purpose of shading and cooling.

5、 More observation: once the disease is found, it should be dealt with immediately, so as to reduce the loss to the lowest level.
