Organic fertilizer is an important source of fertilizer for agriculture. Composting is made of common plant wastes and other wastes, which are added with chicken manure, pig manure, cow dung and other manure for composting and fermentation.
Firstly, straw raw materials (Also available weeds, leaves, garbage and other containing cellulose, hemicellulose, lignin substances) are cut into 6-7cm long by crop straw crusher, mixed with 500kg of straw, 300kg of horse manure, pig manure, cow manure and 100kg of human manure and urine, and then stacked into a rectangular material pile with a height of 1.5m and a width of 5m. Finally, 700-800kg water is poured, and a layer of 3-6cm thick fine soil is covered on the compost surface to keep heat, water and fertilizer. After about one week, the stacking temperature will rise to about 60-70℃ (the time of low temperature consumption will be longer). After 10 days, the fermentation compost tipping machine can turn the compost once and replenish the water; after the second rise of stacking temperature in 10 days, carry out the second turning and replenish the water. The sign of compost maturity is that the material turns black brown and the odor is eliminated. The surrounding area is tightly sealed with soil to keep nutrients in reserve.
The compost can be made into powder organic fertilizer or finished granular fertilizer. In terms of effect, the value of organic fertilizer particles is higher. The organic fertilizer granulator is used to make the compost into particles to improve the practicability of the fertilizer.
How to use organic fertilizer
The application of organic fertilizer can increase the soil fertility, and supplement a large number of soil microbial flora, and bring long-lasting and stable nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and other organic fertilizers to crops, which is conducive to the growth of crops. In production practice, because different crops need different fertilizers, in addition to the application of compost, it is also necessary to apply inorganic fertilizers such as nitrogen, phosphorus, potassium, in order to better play the fertilizer effect. In the batching stage of the organic fertilizer manufacturing process, NPK and other inorganic fertilizers can be mixed to increase the fertilizer effect.
