The accumulation method of farmyard manure is divided into ordinary compost and high-temperature compost. 1, the common compost fermentation temperature is low, and the composition of the decomposition process is not large, the required composting time is longer. 2. High-temperature compost is mainly based on raw materials containing many fibers, and the appropriate amount of horse dung and human urine are added, and the fermentation temperature is higher. There are two methods for high-temperature composting: (1) High-temperature composting on the ground: First, plow 15-20 cm thick chopped straw (about 5 cm) on the ground, and pave corn or stalks into a well-shaped aeration ditch. After the bundles of corn stalks are placed, they are put into the compost materials, and the mud is sealed after the heap is piled. The erected ventilation stalks are pulled out and become ventilation holes. (2) Semi-pit type high-temperature compost: The pit is round (or square), and the stalk column is placed in the trench to facilitate ventilation. The bottom of the pit is covered with a layer of straw, and the thickness is about 3 cm. Spread the chopped compost material to a depth of about 60 cm. Then, dilute the horse manure, human urine and manure mixture (horse excrement, 100 kg of human waste, 250 kg of water) and 4% lime and water.
