One kilogram of fecal fermentation bacteria liquid can ferment 400 kilograms of feces

Chinese farmers have a tradition of using organic fertilizers and attach great importance to their use. In developed countries such as the United States, Western Europe, and Japan, ecological agriculture and organic agriculture are emerging. They attach great importance to the use of organic fertilizers and stipulate organic fertilizers as the main source of fertilizer for the production of green food. The most important thing about applying organic fertilizer is to increase the organic matter in the soil. Although the content of organic matter only accounts for a few percent to a few percent of the total amount of soil in the cultivated layer, it is the core component of the soil and the main material basis of soil fertility. Organic fertilizers have a very important impact on soil structure, nutrients, energy, enzymes, moisture, aeration and microbial activity in the soil.
Organic fertilizers contain a large amount of nutrients needed by plants. They supply nutrients to plants relatively slowly and for a long time, and have a long-lasting effect. Organic fertilizers also contain a variety of trace elements. Since various nutrients in organic fertilizers are relatively complete, and these substances are completely non-toxic, harmless and pollution-free natural substances, this provides necessary conditions for the production of high-yield, high-quality, pollution-free green food. Organic fertilizers contain a variety of sugars, and the application of organic fertilizers increases various sugars in the soil. With sugars and the large amount of energy released during the degradation of organic matter, soil microorganisms have energy for their growth, development, and reproduction activities.
Livestock and poultry manure contains various active enzymes secreted by the animal's digestive tract, as well as various enzymes produced by microorganisms. The application of organic fertilizers greatly increases the enzyme activity of the soil, which is beneficial to improving the soil's absorption performance, buffering performance and stress resistance. The application of organic fertilizers increases the organic colloids in the soil, cements the soil particles into a stable aggregate structure, improves the physical, chemical and biological properties of the soil, and improves the soil's water retention, fertilizer retention and air permeability properties. Create a good soil environment for plant growth.
Organic fertilizer decomposes in the soil and transforms into various humic acid substances. It can promote enzyme activity, substance synthesis, transportation and accumulation in plants. Humic acid is a polymer material with a high cation substitution capacity and good complexing and adsorption properties for heavy metal ions. It can effectively reduce the poisoning of heavy metal ions to crops and prevent It enters the plant. This is very beneficial to the production of pollution-free, safe and hygienic green food.
However, the use of organic fertilizers also has low nutrient content, is not easy to decompose, and cannot meet the requirements for high crop yields in a timely manner. The accumulation and use of traditional organic fertilizers are also very inconvenient. Organic wastes such as human, livestock and poultry manure and garbage are dirty, rotten and smelly substances. They contain many pathogenic microorganisms or are mixed with certain poisons. They are important sources of pollution. It is especially worth noting that with the development of modern animal husbandry, , feed additives are used more and more widely. Feed additives often contain a certain amount of heavy metals. These heavy metals are excreted with animal feces, which will seriously pollute the environment and affect human health.
