"301" compost compost selection places close to water, land, roadside flat land. To compost 10,000 kilograms of straw, it is necessary to use “301” inoculum of 0.5 kg to 1 kg and urea of ​​5 kg (alternatively, 10% of human excrement can be used instead). Stacking and rot method: First dig a groove of 1.5m to 2m in depth, 0.2m to 0.3m in depth, and an unlimited length, place the soil around the tank, and seal it with silt. The straw is piled on the side of the tank to make the straw fully wet, or the straw is first wetted in the puddle and then piled. Wet straws are generally stacked in four layers, each layer is 0.3 to 0.4 meters thick, sprinkled with “301” inoculum and urea on the top of each layer, and the ratio of the amount from bottom to top is 3:3:2. :2. The top of the pile is concave.

Propellant compost selection of places rely on water, land, roadside flat land. The rot of 10,000 kilograms of straw needed to use 1.2 kg of scavengers, and 1 kilogram of scavengers required 80 kilograms of water to dissolve. Stacking and rot method: After the straw and water are fully wetted in a ratio of 1:1.7, the dissolved rot contaminant is uniformly sprayed on the straw by a sprayer, and then the straw sprayed with the scavenging agent is smashed into a width of 1. A stack of 5 meters high and 1 meter high, lightly tapped with a spade (do not compact), take soil and mud seal, thickness of about 1.5 cm.

After “301” inoculum and propellant composting, the temperature should be checked. Generally, the stacking temperature should rise above 50°C after 3 days of stacking. Otherwise, it is mostly due to insufficient moisture in the heap and it can be used to make holes in the heap. Summer 20 days to 25 days can be a good compost, fall 35 days to 45 days.

Enzyme composting (1) Build compost pool. When large-scale centralized production is required, a standard fertilizer tank with cement is required to be constructed. The villager can simply build a compost pool by laying a plastic film on the flat ground and surrounding it with a nylon net or mat to carry out composting. The location should be close to the water source. . (2) Material preparation. Straw 10,000 kilograms, bran 120 kilograms. 20 kg of calcium magnesium phosphate, 16 kg of enzyme-enlarged bacteria, 2 kg of brown sugar, and 4000 kg of dry chicken manure. (3) Method of composting. Straw is first soaked in the compost pool so that the water content reaches 50% to 60%, then the chicken manure is spread evenly on the straw in turn, and the bran and brown sugar (finely ground) are evenly spread on the chicken manure, calcium magnesium phosphate fertilizer and Expand the enzyme bacteria and mix them evenly. Spread them evenly on bran and brown sugar. Then mix well with a fork and pick it into a simple compost pool. The bottom is about 2 meters wide, the pile height is 1.8 meters to 2 meters, the top is arched, and the top is covered with a plastic film to prevent rain.
