Problems solved by technology

[0002] The emergence of chemical pesticides and fertilizers has promoted the development of modern agriculture. However, the excessive use and abuse of pesticides and fertilizers not only lead to the imbalance of soil nutrient ratio, low yield, poor quality and reduced stress resistance of crops, but also cause environmental pollution and food safety. series of questions
In order to solve this problem, people began to use the following fertilizers: 1. Organic-inorganic compound fertilizers contain both organic matter and chemical fertilizer nutrients. It has the characteristics of both organic fertilizers and inorganic fertilizers, but due to its slow nutrient release rate and It cannot meet the supply of nutrients for crops, especially the requirements for the absorption rate of nutrients during the critical nutrient growth period of crops, so it is generally used as base fertilizer application
2. Compound microbial fertilizer is based on the addition of functional microorganisms to organic-inorganic compound fertilizers, but the conventional process is either mixed with chemical raw materials and then granulated, so that the microorganisms will be killed due to high temperature during the drying process; Either it is conventionally wrapped on the surface of the particles, which causes the functional bacteria to fall off easily, and the chemical fertilizer contains more salt ions, which seriously affects the survival of microbial bacteria and reduces the activity
[0004] At present, the sources of biostimulants are relatively wide, but they are mainly used in water-soluble fertilizers and foliar fertilizers. It is rare to use organic-inorganic compound fertilizers and compound microbial fertilizers. The compound fertilizers that appear in the form of coatings are only a single amino acid. Or humic acid products, the coating technology composed of bioglycolipids, compound biostimulants, and microbial bacteria has not appeared
