Ground composting
First compact the ground, then spread a layer of dry fine soil on the bottom, and then lay a layer of uncut corn stalks on it as a ventilation bed (about 26 cm in thickness), and then layer the materials in the bed, each layer thick About 20 centimeters, and poured into the human fecal urine layer by layer (more on the next few). In order to ensure the ventilation in the heap, insert a wooden stick at a certain distance vertically before stacking so that the lower surface is in contact with the ground. After the stack is completed, remove the wooden stick. Composting materials include straw, manure urine and fine soil, the ratio of which is 3:2:5. Adding 2-5% calcium magnesium phosphate fertilizer mixture to the batching can make the calcium magnesium phosphate fertilizer effect significantly improved. After mixing according to the proportion of fertilizer, adjust the moisture to 50% of the wet weight, dig a trench about 30 cm deep and about 30 cm wide around the heap, and soil around. Finally, close the mud heap by 3-5 centimeters and turn it over 2-8 days after stacking. Mix the material with poorly cooked edges and internal materials and re-pile it up. If white mycelium is found in the material, , Add water in an appropriate amount, and then re-close it with mud. When it is half-ripe, squeeze and seal it.
Rapid roticide composting
Using a variety of straw manure and other waste, adding 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) needs 0.5 kg of fungicide, 0.5 kg of urea, and piled on flat ground. First dig 1.5-2 meters deep and 0.3 meters deep in the bottom of the site, and the length is not limited. Within the stack of wheat straw and water, 1 kg of wheat straw should be added with more than 2 kg of water. When the stack is 0.6-0.7 meters high, first spread a layer of urea, spread as much as possible, the amount is half of the total amount, the second layer is 0.4-0.5 meters high, and the remaining inoculum and urea are thoroughly mixed and refilled. The third layer 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.
Summer high temperature compost improves soil fertility
Summer high-temperature compost is one of the main contents of improving soil fertility, and it is also an important way to return straw to the field. At present, it has entered the summer high temperature and rainy season, it is the favorable opportunity for high-temperature accumulation.
