According to the survey, there are 25% of vegetables with serious pesticide residues, which seriously endanger people's health. Resolving pesticide residues and improving the quality of agricultural products are imminent. The main cause of pesticide residues is the use of large amounts of chemical fertilizers to produce nitrates, heavy metals, and other harmful substances in vegetables, causing soil compaction and depletion of soil and increasing pests and diseases; successive applications of pesticides cause serious pesticides in soil and agricultural products. Residues, the resistance of pathogens will also be strengthened. The pathogenic bacteria in the eyes have accumulated over time, causing more and more soil-borne diseases and insect pests. Therefore, the amount of pesticides is getting larger, the toxicity is getting higher and higher, and the pesticide residues are getting worse. We believe that the use of biofertilizer is an effective method to solve the problem of pesticide residues, and it is an effective method for treating the symptoms and treating the disease. It not only has good fertilizer effect, but also reduces the harmful residues such as nitrates and heavy metals caused by the heavy use of chemical fertilizers in agricultural products. , Suppression and killing of pathogens and pests, and thorough disinfection of the soil, elimination of pathogenic bacteria and the spread of pests, is the best measure for the production of agricultural products. Only the elimination of pathogenic bacteria in the soil environment can fundamentally reduce pests and diseases, reduce the use of pesticides or pesticides, and completely eliminate pesticide residues. In addition, bio-fertilizers, especially bio-organic fertilizers, have the following advantages: First, they are highly efficient, long-lasting, and non-polluting. Bio-fertilizers are bio-products that are manufactured using biotechnology, and have specific fertilizer effects on crops, including active microorganisms, microbial metabolites, and transformants. Can play a good fertilizer effect, its core is a beneficial active microorganisms, harmless to humans, livestock, crops; Second, improve the soil, promote the formation of aggregate structure, automatically balance the soil pH, the desertification land and saline land The transformation has a good effect; the third is to save energy and protect the environment, part of the raw materials for biological fertilizer is some animal waste, crop straw, variable waste for the treasure, save a lot of energy, and eliminate two major sources of pollution.
