Chicken manure fast-rotation technology
The chicken manure fermentation method commonly used in the countryside is piled up to allow it to naturally ferment for 4-6 months, so that the odor emits a polluted environment. If chicken manure is fermented with microbial straw rapid decomposer, it can be decomposed in 20 days and it is odorless, odorless and harmless. The compost is soft and yellow-brown. The upper part is pale-white hyphae, and the organic matter can rise to about 48%. Most of the nutrients are present. In the inorganic state, crops are easily absorbed. Now this method is described as follows: 1. Fermentation of dried chicken manure: The chicken manure is first laid flat on the ground (the outdoor cement or land can be) and is in long strips, and is watered at 35% of the weight of chicken manure. 1 kilogram per kilogram of chicken manure and speeding agent (due to the small amount of fast decomposing agent, it is difficult to spread evenly, you can add rice bran or wheat bran to make premix), add 15 kg of superphosphate (for deodorization), add grass powder Or peat 100 kg. Then the compost was tipped over twice and piled into a stack of about 1 meter high, 1.5-2 meters wide and of unlimited length, and several holes were drilled in the top of the pile. Finally, the fertilizer stack is covered with a rectangular plastic cloth, and the plastic cloth is connected with the ground, and a heavy material is pressed every 1 meter so that the film is both ventilated and prevented from being swelled by a strong wind. In the summer and autumn seasons, the membranes are ventilated once and for all (1-2 hours). If the weather is fine, it can be covered in the early morning and the following morning. After 3-4 days of stacking, the stack temperature can rise to 60-70°C. After stacking for 10 days, the stacking can be performed once. The stacking can be cooked for 20 days, and the fertilizer content can be increased to eliminate harmful insects and become an excellent green environmental protection fertilizer. 2, wet chicken manure fermentation: first on the ground to lay a layer of straw powder (rice bran, grass powder, peanut shell powder, peat can), and then spread the wet chicken manure on the top, according to the heap material heavy sprinkled 0.1% urea, according to Each ton of 15 kg of superphosphate was sprinkled in and ground in a premix of 0.2% fast rot (2.5% for fast rot, plus bran or rice bran premixed). The moisture content of the fertilizer heap is controlled at about 50%, and the straw powder can be used to adjust the humidity, and it is appropriate to disperse it with a hand and a group and from a height of 1 meter. Turn the compost over twice and pile it into a stack that is 1.5-2 meters wide, 1 meter high, and has an unlimited length. Use a club to create ventilation holes. Cover with a plastic sheet to keep warm, moisturize, and keep fertilizer. Other management of dry chicken manure fermentation should pay special attention to ventilation.
