In winter, there are many yellow crops and fallen leaves. In addition, a large number of crop straws are recycled. After the capture of fish and shrimp ponds, a large number of pond muds are cleared. If these abundant raw materials are used for composting, sufficient fertilizer can be produced for the spring plowing of the following year, which will not only save costs, but also It is conducive to doing a good job in environmental sanitation and has many advantages. One, stacking method. Ground composting should be selected in the leeward place. When stacking, the ground should be leveled and solidified, and a layer of 3-4 inch thick dry pond mud or dry fine soil should be applied to absorb the infiltrated fertilizer solution. Spread a layer of chopped straw, garbage, weeds, etc., 25-30 cm thick, mixed with some excrement of humans and animals, and then disperse about 2%-3% of the raw lime, splashing liquid fertilizer, sewage, etc. , spread out about 7cm thick thin pond mud, pit mud or gravel. Afterwards, the raw materials are added one by one in turn, layer by layer, and the stack height is about 2 meters, and the width is 3 meters. The length depends on the number of materials. When stacking, the lower layer should be loosened, and the upper layer should be pressed and compacted one by one. In this way, the permeation conditions are good, perishable, and the fertilizers are easy to store and not easily lost. After stacking, use pond mud or thin mud to paste to reduce evaporation of moisture, facilitate heating and heating inside the heap, ferment and decompose, in order to facilitate ventilation and add water, use straw to grow 2 meters thick at the beginning of stacking, roughly 10 centimeters thick In the rod bundle, a bundle of stalks is erected as a stomata from the bottom up every 1 meter or so, and then the stomata can be slowly poured into the water after adding water or liquid fertilizer. Second, add water to promote maturity. Dry in winter, with large evaporation. If moisture is insufficient, microbial activity is inhibited, straw and other debris inside the compost will not be easily rotted, and some water and sewage or sewage will need to be frequently added during the stacking process to make the material inside the heap expand and promote microbiological activities. Fermentation maturity. When composting and adding water, it is better to microscopically display moisture at the bottom of the heap. Third, turn over and promote uniform. During the winter, the compost must be turned 2-3 times during the stacking period. The time for turning each pile must be controlled within a few days after the high temperature in the pile. And add manure, sewage, human and animal dung and so on. When turning, the stacking objects above and around are turned into piles, and the piled materials in the original stack are turned around and covered in the upper layer, so that all the compost materials are ripe and uniform. Fourth, the application method. The compost that has been completely decomposed and bred is generally brown. All the materials are rotted and odorous, rich in organic matter, high in fertility, and long-lasting in fertilizer efficiency. In the coming year, the spring can be used as a basal fertilizer. The application method can be applied as a strip or hole, and the amount of mu is 2000-2,500 kg. It can also be spread evenly on the ground before plowing, then turned into the soil, and then evenly transferred through the depression or paddy fields to make the fertilizer and soil. Integrate, reduce the loss of fertilizer, improve the fertility of the soil, and lay a good foundation for seizing the harvest of crops.
