1.The use of manure should be thoroughly decomposed
The decomposition of manure is decomposed fast and is beneficial to the absorption of plants. At the same time, most of the bad eggs and weeds seed will die in the high temperature anaerobic environment at 60-70 degrees.
There are three commonly used methods to decompose manure:
1)The first is to combine the manure and decayed manure with high temperature sheds. The summer fallow period is long, can be combined with the high temperature disinfection of manure composting, composting process and soil improvement. In the process of fermentation, the microorganisms in the soil are very active, which can promote the formation of soil aggregate structure.
2)The second is the stuffy outside the shed. Have enough time to natural retting fermentation, and the time is short in maturity of pile boring using bio inoculants.
3)The third is to use the bacteria to quickly ferment. The common ETS bacteria can shorten the fermentation time.
2.Choose different manure according to different soil quality
Some greenhouses have large sandy soil and serious leakage water and fertilizer. Therefore, pure chicken manure and pure pig manure should be chosen for manure, the purity of this manure is higher and nutrient content is higher, because the fecal quality is relatively sticky, which can improve the sand land leaking fertilizer and water.
Clay should applying manure with high organic content and mineral elements content of less, such as sheep manure, cow dung or containing sand, rice husk, straw manure, pig manure and other physical properties, can improve the cohesive soil, improve the permeable ability. This is also very suitable for manure to improve the salinization of soil compaction serious greenhouse soil.
3.When manure is used, it should be deeply turned over
A lot of manure is concentrated in the soil of 10-15cm. Although the soil is mixed, the manure is still concentrated. Even if the manure has been decomposed, it will also affect the root growth if the amount is so large and the tillage depth is relatively shallow. So when manure is used, the depth of the manure should be deeply turned over, and the general depth of plowing is more than 30cm.
