I. High-temperature compost technology
1. Ground composting method: Select a place that is close to the water source and convenient for transportation. The size of the fertilizer pile depends on the site and the material. First, ground the ground, then spread a layer of dry fine soil on the bottom, and spread it on the ground. The layer of uncut corn stalks serves as a ventilated bed (thickness about 26 cm), then layers the material in bed, each layer is about 20 cm thick, and pours layer by layer into the human excrement (more on the lower side) to ensure the heap Within the ventilation, insert a wooden stick vertically at a certain distance before stacking so that the underside is in contact with the ground. After the stack is completed, remove the wooden stick. The remaining holes serve as ventilation holes. The composting materials include straw, human and animal waste, and fine soil. The ratio of 3:2:5, adding 2 to 5% of calcium magnesium phosphate fertilizer mixture, can reduce the phosphorus fixation, so that the calcium, magnesium, phosphate fertilizer effect is significantly improved. After mixing according to the proportion of fertilizers, adjust the moisture to 50% of the wet weight. Generally, it is advisable to use drops of the hand material. Dig 30 cm deep and 30 cm wide around the fertilizer heap to prevent soil from growing around. Loss of manure fluid. Finally, after mudlocking about 3 to 5 centimeters, the temperature rises significantly after 2-8 days of stacking, and the heap gradually sinks. When the temperature in the heap slowly falls, it is turned over, and the material that is not ripe at the edges is The internal materials are evenly mixed and re-piled. If white mycelium is found in the material, add water in appropriate amounts and then re-close it with mud. When it is half-ripe, it should be sealed tightly and used.
The signs of compost maturity: When the crop is completely decomposed, the color of the crop stalks is dark brown to dark brown, the stalks are very soft or mixed, the plant residues are not obvious, and the compost is squeezed out of the juice by hand to filter out colorless odors. .
2, fast rot composting method: the use of a variety of straw manure and other waste, add a certain amount of "fast decay agent" to regulate nutrition, inoculation of fermented microbial agents for high temperature composting. Generally every cubic meter of wheat straw (65-70 kg) requires 0.5 kg of fungi, 0.5 kg of urea, flat ground, first dig at the site of 1.5-2 meters wide, 0.3 meters deep bottom tank, the length is not limited, to the tank Within the stack of wheat straw and water, 1 kg of wheat straw should be added with more than 2 kg of water. When stacking 0.6-0.7 meters high, first spread a layer of urea, as far as possible to spread evenly, the amount is half of the total amount, the second layer of 0.4-0.5 meters high, the remaining bacteria and urea and all the same, and then heap The third floor is 0.3-0.4 meters high, artificially practical, plus enough water, and finally take the surrounding mud tightly sealed heap, 7-10 days fat heap uniform collapse, such as collapse is uneven, should be added in the prominent part of the water, 30 days after wheat straw dark brown Or muddy, that is composting compost.
