Microbial fertilizer is not a panacea and needs to be treated rationally
Q: A plant protection station in its experimental field concluded that the use of microbial fertilizers reduced the use of pesticides by 20% to 30%, reduced soil-borne diseases in melons by 30%, and increased production by 15% to 18%; and reduced the use of chemical fertilizers by 40%. Under the circumstances, the same output can be achieved and the taste is greatly improved. Is this data credible? Why is there such an effect? A: This problem is very representative. We need to have an objective and comprehensive understanding of microbial fertilizers. Microbial fertilizers do have unique advantages: it can promote the conversion of materials and energy and recycling, can degrade waste, increase soil fertility and activity, improve crop quality, and contribute to food safety and environmental protection. However, microbial fertilizers can only reduce the application of chemical fertilizers and pesticides to a certain extent. Microbial fertilizers supply limited nutrients. Even rhizobia can only provide 1/3-1/2 of the nitrogen needed for crops, and cannot replace chemical fertilizers; microbial fertilizers The effect of fertilizing and improving soil needs to be based on rich organic materials, and it cannot replace bulk farmyard fertilizers; the plant protection role of microbial fertilizers is mainly to suppress harmful bacteria and increase crop disease resistance, but it has no direct killing effect on fulminant diseases and insect pests. Replace pesticides. Therefore, it is necessary to further test the authenticity and reliability of the experimental field data, and it cannot be concluded prematurely, let alone exaggerating the experimental effects of microbial fertilizers. Q: In the production, some farmers use microbial fertilizer but have no effect. Why is that? A: Microbial fertilizers are new types of fertilizers, and it is necessary to pass three levels to obtain good application effects. The first is the quality of the product: The microbial fertilizer products on the market are mixed. When purchasing, you must check the relevant product licenses. If necessary, you can do a simple comparison test. The second is the transport preservation. The live microorganisms are effective and cannot be used as microorganisms. Fertilizer and chemical pesticides mixed, can not allow direct exposure to sunlight for a long time; the third is a reasonable application of Guan: Before using microbial fertilizers should carefully read the product instructions, after the application of timely summary of lessons learned, and continuously improve the application effect. Q: Microbial fertilizers can control disease and increase production. So, is it fertilizer or pesticide? Answer: Most microbial fertilizers prevent or reduce the occurrence of pests and diseases to a certain extent by increasing crop disease resistance and inhibiting pathogens. However, it cannot directly kill pests and diseases and is therefore not a pesticide. Q: Experts suggest that the use of microbial fertilizers requires the promotion and guidance of grassroots technicians. This is to say that the operation of microbial fertilizers is very complicated? A: It is necessary to strengthen grassroots technical personnel's propaganda and technical guidance on farmers' use of microbial fertilizers. This is not how complicated the operation technology of microbial fertilizers is. It is because China started late in the development and utilization of microbial fertilizers. Farmers do not As familiar as conventional fertilizer, there are even many misunderstandings. Q: The spring of microbial fertilizers has come. Does this have anything to do with the farmers? A: Our government now pays more attention to ecological civilization, development of ecological agriculture, and emphasis on food safety. Fertilizer production, marketing, and application units also place greater emphasis on the development and use of microbial fertilizers than ever before. From this point of view, it makes sense to say that the spring of microbial fertilizers has come. However, it is acknowledged by the world that, if no fertilizer and pesticide are applied at all, crops will be reduced by 30%-40%. Microbial fertilizers and fertilizers, pesticides, and organic fertilizers are still used together.
