Chicken manure is a common agricultural waste and is often used as organic fertilizer. However, before using it, we need to do some treatment to ensure that the chicken manure is free of harmful bacteria and viruses and does not attract pests.
The following are some methods of killing insects and sterilizing chicken manure:
1.Sun disinfection
Spread the chicken manure flat in the sun to dry, so that the ultraviolet rays and high temperature in the sun’s rays can sterilize and kill insects. This method is simple to operate and is more environmentally friendly. At the same time, it can also remove the peculiar smell of chicken manure and improve the fertilizer efficiency of chicken manure. But it should be noted that the sun’s rays will reduce the nitrogen content of chicken manure, and if it rains, the drying effect will be greatly reduced.
2.Fermentation disinfection method
Put chicken manure into a large fermenter for fermentation. During this process, the salt and water in chicken manure will reach a certain concentration, which will inhibit the growth of bacteria. At the same time, heat energy is generated during the fermentation process, which can accelerate the drying of chicken manure and kill parasites. This method can completely eliminate bacteria and pests, but it requires more energy and time.
3.High temperature sterilization
Put an appropriate amount of water in the chicken manure bag, then seal it, and place it in a high temperature environment (50~60°C) for more than 24 hours. This method can not only remove the bacterial flora in chicken manure, but also reduce the content of the minimum chemical nitrogen and ammonia nitrogen contained in the ingredients. If the treatment is achieved using effective high temperature, then in general, the raw material treatment of the farming family is completed, and the harm of diseases and insect pests can be prevented.
4.Heavy metal immersion method
When using chicken manure, a small amount of heavy metals can be added to the manure, which can kill bacteria and insects to a certain extent. This method is relatively simple and cheap, but it should be noted that if the content of heavy metals in the substrate exceeds a certain range, it will have adverse effects on plant growth.
In short, when using chicken manure, it needs to be treated first to ensure the quality of the fertilizer and prevent the invasion of pests and pathogens. At the same time, we need to pay attention to protecting the environment and improving the utilization rate of resources, so as to reduce the waste of waste as much as possible.
