1. The use of manure should be thoroughly decomposed. After being decomposed, manure decomposes quickly, which is good for plant absorption. Three common methods of manure decomposing:
One is to decompose manure in combination with high temperature and stuffy sheds. The summer shed can be combined with the high temperature stuffy shed to decompose manure, and the process of decomposing and fermentation is also a process of improving the soil. During the fermentation process, the microorganisms in the soil can promote the formation of soil aggregate structure.
The second is boring outside the shed. There is enough time to naturally pile and ferment, and when the time is short, you can use biological decomposing agent when the pile is dull and decomposed.
The third is to use bacterial agents for rapid fermentation. Commonly used are ETS flora, etc., which can shorten the fermentation time.
2. Choose different manures according to different soil quality. Some greenhouses have high sandiness and serious water leakage and fertilizer leakage. Therefore, pure chicken manure or pure pig manure should be selected for manure. This manure has high purity and high nutrient content because of the comparison of manure It is sticky and heavy, and has a good improvement effect on the sandy soil that leaks fertilizer and water.
3. After the manure is used, a large amount of manure is concentrated in the soil of 10~15 cm on the surface. Although it is mixed with the soil, the manure is still relatively concentrated. Even the decomposed manure is used in such a large amount and the depth of plowing. Under shallower conditions, it will also affect root growth. Therefore, deep plowing should be carried out after applying manure, and the plowing depth should exceed 30 cm.
4. Note that the combined use of manure contains comprehensive nutrients, but the total amount does not reach the absorption and utilization of crops. Therefore, the combined use of manure and chemical fertilizers can reduce the impact of chemical fertilizer residues on the soil, while ensuring the nutrients in chemical fertilizers It can be absorbed and used by crops in time.
The combined use of manure and biological bacterial fertilizer can accelerate the decomposition of manure and accelerate the rate of soil improvement. The substances in manure can promote the reproduction of biological bacteria and consolidate the protection and growth-promoting effects of beneficial bacteria on the root system.
Manure has a certain effect on soil improvement, but the effect is relatively slow. Therefore, products containing mineral-source humic acid, seaweed extract and other biological stimulants are more effective.
