Using modern equipment to induce autumn buds

It is the height of summer, the sun is burning, and the temperature has risen to 30-38 degrees. The worst and most difficult season for raising orchids has come. From the Internet, we can also see that the orchids raised by orchids are facing severe tests, such as soft rot, black spot, beetle disease and so on, which have brought great losses to the farmers. According to my experience: the first task of this season is to cool down: various cooling measures, such as sunshade, ground sprinkling, wall spraying, fan blowing, carpet storing water on the balcony floor, etc., conditional use of water curtains, air conditioning cooling effect is very significant. The second is watering: although the orchid is fleshy root, but in the summer with strong light and high temperature, the demand for water is relatively increased, and sufficient moisture must be ensured. In addition to normal watering, foliar spraying should be carried out before and after morning and evening to increase air humidity. There is spraying: orchids are extremely prone to diseases and insect pests in summer, and fungicides such as chlorothalonil or methyl thiophanate, carbendazim, mancozeb and other fungicides can be sprayed every 10 days to control the occurrence of leaf anthracnose and white silk soft rot. 40% omethoate and triclofenac are sprayed every semimonthly, which can kill shell insects and mites. Only in this way can Lan spend the summer safely. In fact, all this is my experience of making use of all available conditions to raise orchids when summer comes a few years ago. And now in summer, my Laner lies quietly in the air-conditioned room to enjoy the cool summer. All the above concerns are less considered, and more considerations are given to how to use technology to automatically control the temperature at 20-28 degrees and the temperature difference between day and night to about 10 degrees, because the best growth temperature for spring orchids is about 20 to 28 degrees. The two biggest advantages of this are 1. Laner enters a period of rapid growth in midsummer, and bluegrass has grown into seedlings by the end of August. two。 Due to the coolness of summer, the physiological conditioned reflex of plants is mistaken for autumn, which can induce autumn buds in advance and bring great benefits to the growth of summer buds, but what we should pay attention to here is the humidity control of the orchid room. the relative humidity should be controlled at about 75%, and the orchid pot should not be too dry, otherwise many flower buds will be forced out [after using air conditioning, most flower buds are unearthed at the end of July]. In order to let the orchid safely through the midsummer into the crisp autumn ushered in the second growth period. Let's work together!
