Biological organic fertilizer features: biological organic fertilizer nutrient elements complete, provide comprehensive nutrients for crops; With high organic matter content, bio-organic fertilizer can improve soil, improve soil physical and chemical properties, enhance soil water retention, fertilizer retention and fertilizer supply capacity, and alleviate soil compaction caused by long-term use of chemical fertilizer. Beneficial microorganisms in bio-organic fertilizer enter the soil and form a symbiotic proliferation relationship with microorganisms in the soil, inhibit the growth of harmful bacteria and transform into beneficial bacteria, interact and promote each other, and play a synergistic role in the group. Beneficial bacteria produce a large number of metabolites in the growth and propagation process, promoting the decomposition and transformation of organic matter. Can directly or indirectly provide a variety of nutrients and stimulant substances for crops, promote and regulate crop growth. Bioorganic fertilizer increased soil porosity, permeability exchange and plant survival rate, and increased beneficial bacteria, soil microorganisms and population. At the same time, the beneficial bacteria group formed in the root system of crops can inhibit the propagation of harmful pathogens, enhance the resistance to disease and reduce the disease index of repeat crops, and successive application can greatly alleviate the obstacles of continuous cropping. Biological organic fertilizer recycling agricultural waste, reduce environmental pollution, human, livestock, environmental safety, non-toxic, is a kind of environmental fertilizer.
The development trend of bio-organic fertilizer: At present, countries all over the world pay great attention to the sustainable development of agriculture, and constantly increase the development, production and application of bio-organic fertilizer. Although China's bio-organic fertilizer industry has made some progress, due to various reasons, there are still some deficiencies and need to be improved. In the future
Efforts should be made in the following three aspects in the development of bio-organic fertilizer.
1. Improve product quality: Improve the quality of biological organic fertilizer products, mainly from the three aspects of strain breeding, process optimization and development of new products. In terms of strain breeding, the mining and utilization of agricultural microbial strain resources with specific functions such as promoting root growth, transforming soil nutrients, preventing and controlling soil-borne diseases, reducing and passivating toxic and harmful substances in the rhizosphere should be increased. In addition, in order to ensure that the products in the process of processing, transportation, storage and other processes still maintain high biological activity, should strengthen the application of strong stress resistance Bacillus. In the aspect of process optimization, research and development and establishment of different solid organic waste compost utilization technology and process, according to different sources of waste, establish supporting process and technology, in order to meet the changing needs of organic waste resource utilization industry. At the same time, the process parameters are optimized to improve product quality, shorten production cycle and reduce production cost. In the development of new products, combined with the actual production, to increase innovation. The research and development of bio-organic fertilizer should be strengthened in the future. In short, it is a fertilizer containing inorganic nutrients, functional bacteria and organic matter. It can not only provide enough nutrients for crops in season, but also add beneficial bacteria and organic matter to the soil and improve the microbial flora in the soil, so that the soil with disease and slow nutrient conversion gradually becomes healthy soil and fast nutrient conversion soil. In the future, we should strengthen the research and development of the compounding technology and process of bio-organic fertilizer, so as to produce bio-organic fertilizer products suitable for different soil, different crops and different climatic conditions.
2. Standardize product management: At present, there are a wide variety of biological organic fertilizer products on the market, with rich and varied packaging and uneven quality. In view of these problems, relevant industry management departments should strengthen the detection and supervision of products, and crack down on fake and shoddy behaviors on the market.
3. Increase promotion efforts: The government, enterprises and relevant agricultural technical departments should work together to strengthen the publicity and promotion of bio-organic fertilizers. The application effect of bio-organic fertilizers can be demonstrated to farmers through demonstration, explanation and on-site guidance, so that farmers can fundamentally understand the economic and ecological benefits of bio-organic fertilizers, and improve the enthusiasm of farmers to use bio-organic fertilizers.
The minister of Agriculture and Rural Affairs said at the National Agricultural Work conference that the promotion of organic fertilizer replacement of fruit, vegetable, tea and biological organic fertilizers will help optimize the variety structure of agricultural inputs, improve soil, improve fertility and improve crop rhizosphere microflora. The zero growth of fertilizer use action plan formulated by China clearly states that "two optimizations" should be achieved in the structure of fertilizer use: optimizing the ratio of nitrogen, phosphorus and potassium to promote the coordination of large elements with medium and trace elements; Biofertilizers should be regarded as an important part of accelerating the promotion of new products, and effective measures should be taken to promote the popularization and application of biofertilizers. In the future, bioorganic fertilizer will be taken as an important measure to promote fertilizer reduction and efficiency, and the media will be fully used to increase publicity and guidance, so as to let farmers understand the efficacy of bioorganic fertilizer in improving soil, fertilizing soil capacity, improving crop quality, reducing agricultural non-point source pollution and so on, and improve their initiative in applying bioorganic fertilizer. In the future, we will continue to improve fiscal and tax policies to encourage the production and use of organic fertilizers and biological organic fertilizers, further increase support, promote the healthy development of the organic fertilizer industry, and accelerate the popularization and application of organic fertilizers.
Comprehensive above: we concluded that the development and application of biological organic fertilizer can not only create conditions for the development of green agriculture, organic agriculture, but also the organic waste "waste into treasure" to achieve resource utilization, with higher economic benefits, ecological benefits and social benefits, is to achieve a strong guarantee of sustainable development of agriculture. In the future, bio-organic fertilizer will become a hot spot in the production of fertilizer industry and the consumption of agricultural materials, and has a broad development prospect. It will be the most promising fertilizer!
