Switching to vegetable greenhouses or using some small techniques can improve the growth conditions of vegetables in the greenhouse and increase their yield and quality. 1. Garden soil disinfection. Each square meter of garden soil is treated with 3 to 5 grams of carbendazim or methyl bromide, which can kill pathogenic bacteria in the soil and prevent the occurrence of soil-borne diseases. 2, double layer coverage. Covering the mulch or adding a small arch shed in the greenhouse, covering the mulch can increase the temperature of the soil surface by 2 °C, and adding a small arch shed can keep the temperature of the vegetable growing environment above 15 °C. 3. Improve the filming method. The use of iron wire instead of bamboo rafts, bamboo frame film, and plastic rope instead of bamboo rafts as climbing objects can reduce the opacity and improve the photosynthetic efficiency. 4. Improve irrigation methods. The drip irrigation or submerged drenching method can replace the traditional flood irrigation, which can reduce the relative temperature of the air in the shed by more than 10%. 5. Use no drip film. No dripping film will not condense water droplets, and the light transmittance can reach 98% or more. If a general shed film is used, it can be applied to the shed film or the daily cleaning can be carried out to eliminate water droplets on the film and enhance the light. 6, sprinkle grass ash. In the greenhouse, the hay ash is often sprinkled, which can inhibit the occurrence of diseases such as vegetable collapse and blight, and promote the healthy growth of vegetables. 7. Add carbon dioxide. The burning of biogas in the shed not only increases the temperature of the shed, but also supplements the carbon dioxide gas. 8. Set up the reflective screen. A reflective screen is placed on the back wall of the shed to enhance the light in the low light area and increase the ground temperature by 2-3 °C. 9. Apply a growth regulator. Proper application of exogenous plant growth hormone can promote plant growth and control the fall and fall of fruit. 10. Clever use of pesticides. The application method of dust, smoke, etc., has no spray application method to increase the relative humidity of the air in the shed, and is simple and easy to operate, and the effect is stable and lasting.
