How to make high quality duck manure composting fertilizer?
1. In order to solve the problem of high humidity in duck dung, we must first reduce the mercury content in duck dung. The cost of using separate water harmless treatment equipment is high, the technology is difficult, and the treatment capacity is small, the cycle in the fermentation tank is long, and the old one has entered the fermentation tank before the new one comes out). Therefore, we can add wheat straw, corn straw, rice straw, rice husk powder, peanut seedling powder, sugar aldehyde residue, soybean cake, oil and other auxiliary materials with low water content.
On the one hand, it can reduce the water content of duck manure, on the other hand, it can increase the content of organic matter after fermentation composting. Straw, husk bran, cake and dregs were crushed by water drop stone crusher. After the crusher was even, straw and other auxiliary materials were mixed with duck manure at the ratio of 3:1 (high moisture content) or 1:1 (low moisture content) to start fermentation.
2. In the process of fermentation, it is necessary to constantly turn over the pile to promote the oxygen to enter into the pile body to prevent the poor air circulation and produce ammonia, so as to generate a large number of bad smell. Therefore, several thermometers can be inserted into the fermentation pile to observe and measure the composting temperature of duck manure at any time. When the temperature of duck manure fermentation pile increased to above 50c, the trough type dumper was used to turn the pile, and the pile was turned every 2-3 days to ensure that the temperature of the pile did not exceed 60C
3. The trough dumper is composed of two parts: dumper and shifting car
When the temperature of the pile decreased slowly and kept between 30-40 ℃, it indicated that the enzyme value stage began to enter the late decomposition stage. At this time, stop turning the pile and wait for the self decomposition of fermentation materials. This stage takes about 7-10 days. After fermentation, if there is caking phenomenon, you can use the previous drip mill to crush again, so as to improve the appearance quality of powdered organic fertilizer, and it is also a simple and fast method to reduce the caking hardness of duck manure.
