The method of stacking and fermenting can stack wheat stalks on the ground, that is, laying a layer of film on the ground, spreading wheat stalks into a layer of 50 cm in height, 2 meters in width, and of unlimited length, and then spray water to spray wet. Spraying, it is appropriate to slightly drown on the ground, and finally sprinkle a layer of urea on wheat straw, which is 0.5% of the weight of wheat straw. According to the above method, three layers are laid, and one stick is inserted every 1 to 2 meters to facilitate ventilation. Check once every 20 days or so, you can turn and add water according to the actual situation. Stacking site must be selected sunny, the temperature reached 50 °C. Can also be sprayed on the wheat stalk EM bacteria, CM bacteria, enzyme bacteria 200 ~ 300 times the original liquid fermentation, each layer must be sprayed thoroughly, the basic approach ibid, but the temperature must be controlled to 35 °C ~ 38 °C is appropriate. Wheat stalks after storage are yellow-brown and fragile and can be used as basal fertilizers.
The effect of mixing with cyanamide calcium is good. Each mus mower applies 1000 to 2000 kg of chopped wheat straw and 150 to 200 kg of calcium cyanoaminate, and then deep-turns 30 cm, pouring enough water, and the temperature is high for about 30 days. 10 days after ventilation, plants can be planted. This method not only kills root-knot nematodes but also disinfects the soil. It also increases organic matter and nitrogen nutrients in the soil.
The benefits of direct furrowing are mostly in the greenhouse, along the cultivation line, digging trenches, with a furrow depth of 30 cm or more, applying more than 10 kilograms of crushed wheat straw per furrow, if combined with the application of fully decomposed organic fertilizer, fungus fertilizer or chitin Well, not only can increase the soil fertility, but also can increase the permeability of the soil, but also prevent crop root disease to prevent dead trees. In the case of no application of bacterial fertilizer, apply 68% of Jinlei suspension agent 10g per ditch, and mix with the soil to prevent vegetable seedling disease epidemic disease dead trees significantly. One should be filled with water at the time of application, and the second one should be high temperature stuffy shed for more than 15 days (except for the application of bacterial fertilizer).
The application of treated wheat straw in the greenhouse can not only increase soil organic matter and trace elements, and fertility, but also change the physical and chemical properties of the soil, enhance the respiration, absorption, synthesis and transport functions of vegetable roots, and increase vegetable yield and quality.
