The first step of cow manure organic fertilizer is fermentation
With the rapid development of cattle industry, manure pollution has become a major problem. According to relevant data, in some places, the environmental pollution caused by cow dung is as high as twice as much as that of industrial pollution. In fact, cow dung has many uses. In the past, it can be used as the base fertilizer of crops after direct fermentation. Now, manure can be turned into treasure, and organic fertilizer production equipment can be processed into organic fertilizer, so as to obtain higher quality How to process cow manure into organic fertilizer?
1. One bag (200g) of cow dung composting starter and 3kg rice bran (straw powder, sawdust, wheat bran and rice bran) were made into strain mixture for standby.
2. The mixture of the above-mentioned bacteria is evenly sprinkled into 2-3 cubic meters of composting cow dung, and the moisture content of the whole material is maintained at about 50-60%. The moisture standard of the material is as follows: pinch it into a ball, there is a watermark, no dripping, and it will disperse when you let it go. If possible, you can set a canopy on the pile or cover it with a layer of plastic film to prevent rain from getting wet.
3. The organic fertilizer machine must be even and thorough when turning over the pile. The low-level special materials should be turned into the middle and upper parts of the pile as far as possible, so as to fully mature. After turning the pile once, it will be turned over once a week. However, when the temperature exceeds 70 ℃, the pile must be turned over immediately. Otherwise, a large number of beneficial microorganisms and fermentation bacteria will be killed, which is not conducive to fermentation and maturity.
The processing of cow manure into organic fertilizer can effectively reduce the pollution it brings, and to a certain extent, it also has great help to the production, so we must carry out organic fertilizer treatment on cow manure to play a greater role.
Organic fertilizer production line can be made into: spherical granular, cylindrical, flat spherical. The granulator equipment used varies with the particle shape. Disc granulation, drum granulation, agitator granulation, the materials produced by these three pelletizing methods are spherical; the organic fertilizer produced by the double roller granulator is flat spherical, etc., and there are many kinds of pelletizers for you to choose from.
