1. Raw materials are prepared to produce one ton of enzyme organic fertilizer, 300 kg of corn stalk (straw and bean stalk), 200 kg of chicken manure, 0/00 kg of rice husk/kloc-0, 0/00 kg of sawdust/kloc-0, 300 kg of pure land, 3 1 kg of enzyme, 2.5 kg of urea.
2. Composting method: Chop rice straw and bean straw into lengths of about 2cm with a straw cutter, add water and stir evenly, then mix chicken manure, rice husk, sawdust and No.3 enzyme in proportion, and then smash. If there is a big carat in the pure land, crush it. After the composting site is selected, the bottom of the pile is paved with bricks with ventilation channels at intervals of about 7-8cm, and grass curtains are laid on them. Straw is covered with a layer of 25cm straw, covered with a layer of urea (1/3 or so), covered with a mixture of chicken manure, rice husk, sawdust and enzyme No.3, and covered with a layer of 65438+. The top is sealed with a layer of soil. The bigger the pile, the better the insulation effect. Because of the low temperature, it is best to put a heat source in the pile when fermenting. One is to build an empty room with bricks in the middle of the pile, and install 100w light bulb as the heat source. It takes about 2-3 days in the early stage, and the power can be cut off when the temperature in the reactor rises to about 60℃. Second, pile 3-4 baskets of horse manure in the middle and add some hot water, which is also very effective as a heat source. ?
The general production season should be May to September. Too early or too late will affect the production effect of organic fertilizer because the temperature does not come up.
4. Precautions: 1. Temperature management, the temperature of fermentation pile is gradually increasing. Generally, after 5-6 days, the temperature in the reactor can rise to 60-65℃, and after 3-4 days, the temperature in the reactor drops slightly, and then rises again after 3-4 days. When the temperature rises to 60-65℃, it is poured out again. The second is water resources management. In the reverse process, if insufficient water is found in the pile, water should be added in time to keep the water content at about 40%. At this time, the fermented product can be held tightly by hand and can be agglomerated. ?
