First, double coverage: in the greenhouse to cover the film or add a small arch. Covering the film can increase soil surface soil temperature by 2°C. Adding a small arch can keep the temperature of the vegetable growing environment above 15°C.
2. Disinfection of garden soil: Use 3-5 grams of carbendazim or methane bromide per square meter of bed soil to kill pathogens in the soil and prevent the occurrence of soil-borne diseases.
Third, to improve the way of membrane: Use bamboo wire instead of bamboo, bamboo film, plastic rope instead of bamboo sticks as a climbing object, can reduce the degree of shading and improve photosynthetic efficiency.
Fourth, improve the way of irrigation: the use of drip irrigation or submerged irrigation under the film instead of the traditional flood irrigation, the relative humidity of the air within the shed can be reduced by more than 10%.
Fifth, the use of non-dropping film: This plant will not aggregate water droplets, the light rate of up to 98%. If you use a general film, you can apply metronidazole or daily cleaning on the film to eliminate water droplets on the film and enhance light.
6. Scraping wood ash: In the greenhouses, hay ash is often thrown in, which can prevent the occurrence of damping-off diseases, blight and other diseases, and promote the healthy growth of vegetables.
7. Increase carbon dioxide. The burning of biogas in the shed increases the temperature of the shed and adds carbon dioxide gas.
Eight, set the light curtain. The light curtain is set on the back wall of the booth and the vertical floor is at the bottom to enhance 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 hormone can promote plant growth and prevent flowering and fruit drop.
X. Ingenious application of drugs. The use of dust, smoke and other methods of application, there is no lack of spray application of the humidity of the defects, but also simple and easy, and the drug efficacy is stable and lasting.
