At the moment, vegetable farmers who cultivate winter-season vegetables have to start preparatory work before planting. So what needs to be done before vegetable greenhouses are used?

Modulating nutrient soil Nutrient soil is prepared from fertile garden soil, decomposing circle fertilizers or composts that have been prepared in advance. Peat soil can also be used as a condition. The above fertilizer is supplemented with some fully cooked manure and calcium superphosphate. The formula is: 6 kinds of loamy soil not planted with the same kind of vegetables, 4 parts of decomposed farmyard fertilizer, plus 20 to 25 kg of farmyard manure per cubic meter of mixed soil, 1.5 kg of compound fertilizer, 50% of carbendazim powder 0.08 Kg, superphosphate 2 kg, sieving heap, cover the film, stuffy for a while to use.

Prepare seedbeds with nutritious soil seedlings or sowing seedlings. The nutritious soil can be spread directly on the seedbed. A few days before sowing, the original soil in the seed bed was excavated to about 10 cm, the bottom was laid flat, and 12 cm thick nutritious soil was filled in and laid out again. Melons and legumes are generally not divided into seedlings in the nursery process, and nutritious earthworms should be used to grow seedlings. Nutritious soils can be filled with nutrients and nutrients can be densely packed on nursery beds. Sealing to prevent running after sowing. High temperature stuffy shed disinfection high temperature boring shed disinfection, and with the disinfection of drugs can effectively kill a variety of bacteria. About 15 days before the use of greenhouses, spray more than 10% of dust on the floor of the shed, 1 kg per mu; then deepen the soil and close the greenhouse; apply 45% chlorothalonil smoke agent and spray 1 kg per acre. After smoking, continue to close the greenhouse, the use of sunlight to form a high temperature inside the shed, to make a boring shed; 7 to 10 days after the high temperature boring shed, available 50% carbendazim WP 800 times solution to the skeleton in the greenhouse, the ground, the wall Spray it again. Preparation of fertilizers and fertilization for proper application of organic fertilizers on ridges is beneficial to the high yield and quality of vegetable crops, but the applied organic fertilizers must be fully cooked, otherwise they are prone to burning. The organic fertilizer that is to be applied to the greenhouse is moistened with water for 50 to 60 days in advance, piled up, covered with a plastic film, fully fermented, and then applied after decomposition. In the cold season, it is best to do it in a greenhouse or other hot places. The fertilized fertilizer can be spread in the greenhouse, and then deep-turned, leveled, and ridged. (Chen Ligang)
