1, disinfection of garden soil. Each square meter of bed soil is treated with 3-5 grams of carbendazim or methyl bromide, which can kill pathogens in soil and prevent soil-borne diseases from occurring. 2, double insulation. Placing the plastic film in the greenhouse can increase the ground temperature by 2°C. A small arch canopy can be built in the greenhouse. The temperature inside the small arch can be maintained at more than 15°C. 3, improve the way of membrane. Instead of bamboo rafts and bamboo scaffoldings with steel wire, bamboo rafts instead of bamboo rafts are used as climbing objects to reduce shading and increase photosynthetic efficiency. 4, improve irrigation methods. Using drip irrigation or subsurface irrigating instead of traditional irrigation can reduce the relative humidity of the air in the shed by more than 10% and reduce the disease. 5, use drop-free film. This kind of shed film will not condense water droplets, and the light transmittance can reach more than 98%. If you use a general film, you can use metronidazole on the film or stick to it every day to eliminate water droplets on the film and enhance light. 6, append grass ash. Spreading hay ash in greenhouses can prevent the occurrence of such diseases as damping-off and blight, and promote the robust growth of sheds. 7, increase carbon dioxide. The burning of biogas in the shed can increase the greenhouse temperature, supplement carbon dioxide gas fertilizer, and increase the yield of cucumbers, tomatoes, green peppers and cauliflower by about 30%. Where conditions permit, when carbon dioxide is compressed in the cylinder, it is loaded with a plastic tube and released into the shed. 8, set the light curtain. Set up a light curtain on the north side of the booth and hang it down to the ground to increase the light in the low-light area and increase the ground temperature by 2°C to 3°C. 9. Apply growth regulators. The correct use of exogenous plant growth hormones, such as 24-D, anti-dropping agents, etc., can promote plant growth and prevent flowering and fruit loss. 10, clever drug application. With methods such as covert application, dust application, and smog application, there are some drawbacks brought about by spray application, which is also simple and easy, and the efficacy is stable and lasting.
