1. When the plastic bag is decomposed, place a plastic tube with a length of 7 to 8 meters and fasten one end with a thin rope, and place it between the rows of vegetables. Load 150-200 kg of chicken manure from the other end, and leave an appropriate gap in the bag and not be too full. Then, pour water into it, the amount of water is suitable to submerge the chicken manure, and then tie the mouth tightly to ferment, and it can be completely decomposed in 5 to 6 days. Note that both ends of the plastic tube must be fastened tightly, so that the water in it does not flow out. If you want to speed up the rate of decomposing and prevent incomplete decomposing, you can add a decomposing agent with high fertility. This method is simple and easy to operate, fast to decompose, and will not cause gas damage to the vegetables in the shed.

2. Pile the chicken manure to be decomposed naturally on the cement floor or on the mud floor covered with plastic film, and pile the chicken manure into long stacks with a height of 1.5 to 2 meters and a width of 1.5 to 3 meters. The length of the stack depends on the size of the site and the size of the chicken. Depends on how much feces. Add an appropriate amount of water (about 55%), and then cover it with a plastic film, so that the compost naturally heats up to above 50°C, killing pathogenic bacteria and parasite eggs. Note that the dung heap should not be too airtight, so as to avoid lack of oxygen, and microorganisms cannot multiply in large numbers. You can mix a certain amount of sawdust, chaff or straw, wheat, corn and other crop stalks when they are decomposed, and make the film and the dung heap have a certain gap. In order to improve air permeability, supplement oxygen, and promote the rapid and massive reproduction of microorganisms. Adsorbents such as superphosphate, zeolite, and raw soil can also be sprinkled into the chicken manure to absorb the odor generated during the fermentation process.

3. The biological preparations are decomposed as above, but before decomposing, spray decomposing agents such as antibacterial 968 with high fertility on the chicken manure, and then compost or turn it into the soil to quickly deodorize and decompose. Using this method to decompose chicken manure is fast and effective.

4. Earthworm treatment Put specially raised earthworms into the device for holding chicken manure, and expel the earthworm manure through digestion, which can be directly used as fertilizer without fermentation. This method can save energy and utilize the natural ecological cycle to make chicken manure harmless, but the treatment amount is small, and the treated chicken manure has a high water content.

5. Decomposition pond in the greenhouse. Build a pond with a volume of about 2 cubic meters at the west end of the greenhouse near the shed mouth, put chicken manure in, add a biological decomposing agent with high fertility, and then irrigate the vegetables. However, when decomposing in the greenhouse, be careful not to conduct it in the severe winter and under the condition of limited ventilation in the grate in cloudy and snowy weather, so as to avoid excessive accumulation of harmful gases such as ammonia gas generated during the decomposing process in the greenhouse, causing gas damage. This method is mainly aimed at the release of heat and carbon dioxide during the decomposing process of chicken manure, which are most needed by vegetables in the shed in winter, which can be said to serve multiple purposes.
