Shedding shed green fertilizer efficient doorway
Green manure is rich in organic matter, and it can promote a large number of beneficial microorganisms and improve soil structure in a short time after being turned into soil. In recent years, many vegetable farmers have realized the benefits of green manure. However, there are also many farmers who report that the effect of using green manure is not good. The survey found that there are many ways to grow green manure crops. First, choose the right type of green manure First of all, choose green manure types according to the environment of the greenhouse. For old sheds that have been planted for many years, soil problems are outstanding. In particular, large amounts of chemical fertilizers and heavy cropping are used, resulting in serious soil compaction and salinization. Green manures such as spinach and corn with strong fertilizer absorption and potassium release capacity should be selected. The indoor worms in sheds are seriously damaged, and they can be used as green manure for crops such as pyrethrum and green onions; the newly-built shed, the original cultivating layer is destroyed, the existing soil is all raw soil, and the content of soil organic matter is low. Legume green manure, such as clover, alfalfa, soybeans and so on. Second, choose the type of green manure according to the length of rest period. Summer crops grow fast, such as planting oilseed rape, garland chrysanthemum, spinach, etc., can produce tens of kilos of green manure per acre within one month, while crops such as clover, marigold, welsh onion, etc. have a relatively longer growth period, and the greenhouse is in rest period. It's generally about two months or so. Second, turn a good green fertilizer off 1. Pay attention to rollover time. In general, the suitable turning time for legume green manure is from flowering stage to flowering stage; the suitable turning time for grass manure is heading stage; the suitable turning time for cruciferous manure is upper flowering mantle stage. In addition, it should be noted that once the green manure is broken, it should immediately turn over, and it should not be allowed to dry and then turned over. 2. Note the amount of overturning. With the increase in the amount of manure overturning, the effect of fertilizing fertility gradually increases, but the number of manure burial is not as good as possible. Excessive burial, post-cultivation vegetables are prone to vegetative overgrowth, and the harmful substances produced during the decomposing process of green manure can cause vegetable root poisoning. 3. Pay attention to the method of overturning. The overturning of green manure should be carried out about 20 days before the planting of the mandible. The green manure and leaves can be cut into 10-20 cm long, sprinkled on the ground or in the ditch, and then plowed into the soil. The depth of pressure is 10-20 cm. It is advisable that the sandy soil can be deeper and the clay can be shallower. When the pressure is turned, the bottom fertilizer used by the lower quail vegetables can be turned into the soil together and watered to ensure proper soil moisture, and the green manure can be quickly rotted and decomposed. Before planting the vegetables, the soil should be deep-sweeped again to improve the soil permeability and increase the depth of the plough layer.
