How to use modern equipment to induce autumn shoots

It is now the height of summer, the sun blazing like fire, and temperatures have risen to 30-38 degrees.Growing orchidsThe harshest and most difficult season has arrived. From the internet one can also see that theorchidsgrown by orchid enthusiasts are all facing severe tests,soft rotdisease, black spot disease, scale insect infestations and so on occur from time to time, bringing great losses to growers. Based on my experience: the primary task in this season is cooling down: such as shading, sprinkling water on the ground, spraying water on walls, a gentle breeze from an electric fan, placing water-retaining carpets on the balcony floor, and various other cooling measures; if conditions permit, using water curtains or air conditioning for cooling has a very notable effect. The second is watering:orchidsalthough they have fleshy roots, in summer with strong light and high temperatures, their water requirements relatively increase, and sufficient water must be guaranteed. In addition to normal watering, spray the leaves morning and evening to increase air humidity. Then there is spraying chemicals:orchidsin summer are extremely prone topests and diseases, so every 10 days spray once with chlorothalonil or thiophanate-methyl, carbendazim, mancozeb and other fungicides to prevent and control leaf anthracnose and southern blightsoft rotdisease; every half month spray once with 40% omethoate and dicofol, which can kill scale insects and mite pests. Only in this way can orchids safely pass the summer. Actually all of this is just a bit of my experience from several years ago when summer came, fighting the elements and using every available condition to grow orchids well. But now in summer my orchids lie quietly in an air-conditioned room enjoying the coolness of summer. All the above worries are rarely considered anymore, and more consideration is given to how to use technology to automatically control the temperature at 20-28 degrees and adjust the day-night temperature difference to about ten degrees, becauseCymbidium goeringiithe optimal growing temperature is around twenty to twenty-eight degrees. This has two greatest benefits: 1. In midsummer the orchids enter a rapid growth period, and by the end of Augustorchid plantshave all grown into mature seedlings. 2. Due to the coolness of summer, the plant's physiological conditioned reflex mistakenly thinks autumn has arrived, which can induce autumn shoots early and also brings great benefits to the growth of summer shoots, but what must be noted here is the control of humidity in the orchid room; relative humidity should be controlled at around 75%, and the orchid pots should not be too dry, otherwise many flower buds will be forced out [after using air conditioning, most flower buds had emerged from the soil by the end of July]. In order for orchids to safely pass the midsummer and enter the crisp, bright autumn to welcome the second growth period, let us all work together! Author: Ge Xinxing
