Research progress of microbial Fertilizer at home and abroad

Microbial Fertilizer is a product containing specific microorganisms, which is used in agricultural production. Through the life activities of microorganisms contained in it, it can increase the supply of plant nutrients or promote plant growth, increase yield, and improve the quality of agricultural products and the agricultural ecological environment. At present, microbial Fertilizer includes microbial inoculants, bio-organic Fertilizers, and compound microbial Fertilizers. So what is the research progress on microbial Fertilizers at home and abroad? Let's see together.

Here is the content list:

  • l Microbial agent

  • l Bioorganic Fertilizer

  • l Compound Microbial Fertilizer

Microbial agent

As early as the mid-1890s, the Rhizobium inoculant developed in Germany is the earliest microbial inoculant in the world. In the 1930s and 1940s, the United States, Australia, and other countries successively developed the rhizobia inoculant industry. According to incomplete statistics, microbial inoculants have been developed and applied in more than 20 countries and regions, especially in developed countries, the use of microbial Fertilizers accounts for more than 20% of the total Fertilizer input.

In the 1930s, the related research on soybean rhizobia in my country opened the door to the research of microbial inoculants. In the 1950s, the production and application of microbial inoculants began to take shape, and soybean rhizobia inoculation technology was widely used in Northeast China, with an average yield increase of more than 10%. In 1958, my country's agricultural development program listed bacterial Fertilizer as an important agricultural technical measure, which greatly promoted the research and application of microbial Fertilizer. From the late 1960s to the 1970s, my country set off a boom in the research, production, and application of microbial Fertilizers. Nitrogen-fixing blue-green algae Fertilizer, "5406" antimicrobial Fertilizer, VA mycorrhizal Fertilizer, biological potassium Fertilizer, and other microbial Fertilizers have been widely used. In the late 1980s, to meet the needs of agricultural development, the research on microbial Fertilizers gradually developed from a single nitrogen-fixing inoculant to a compound multi-functional inoculant and bacterial Fertilizer and derived bio-organic Fertilizers and compound microbial Fertilizers.

Bioorganic Fertilizer

Bio-organic Fertilizer has the dual advantages of microbial inoculants and traditional organic Fertilizers. In addition to high organic matter, it also contains microorganisms with specific functions. Since the mid-1980s, developed countries such as the United States and Japan have begun to pay attention to the research and application of bio-organic Fertilizers. The raw materials are mainly livestock and poultry manure, urban domestic waste, and agricultural and sideline products such as straw and bagasse are added. With the development of horizontal drum-type and vertical multi-layer livestock and poultry manure composting devices in Japan, the development of high-temperature composting systems composed of large rotary bioreactors and dynamic high-temperature composting systems composed of closed large-scale fermentation in the United States, as well as the development of microorganisms With the progress of deodorization technology, the research, and application of bio-organic Fertilizer are gradually developing towards the direction of systematization, standardization, and harmlessness. In recent years, with the continuous increase of agricultural solid organic wastes such as straw, livestock, and poultry manure, and the continuous decline in the quality of cultivated land, the pressure on resources and environmental protection is increasing, and arable land quality protection and improvement, fruit and vegetable tea organic Fertilizers to replace chemical Fertilizers and other actions have effectively promoted the development of bio-organic Fertilizers in China.

Compound Microbial Fertilizer

The compound microorganism Fertilizer integrates microorganisms, organic nutrients, and inorganic nutrients, which not only overcomes the problems of low nutrients and the slow effect of traditional microbial Fertilizers, but also meets the needs of green agricultural development, and can achieve the purpose of reducing the number of chemical Fertilizers, increasing production and improving quality. How to combine inorganic nutrients with specific living microorganisms is the key to the production of complex microorganism Fertilizers. Inorganic nutrients are a variety of salts, and high concentrations can inhibit microbial growth. By breeding Bacillus with strong stress resistance, and with an appropriate production process, the microorganisms can be kept in a dormant state before compounding, or the organic materials and microorganisms are granulated together, and the inorganic nutrients are granulated separately. Minimize the impact of adverse conditions on microorganisms.

The above is the relevant content about the research progress of microorganism Fertilizer at home and abroad. If you are interested in Fertilizer, you can contact us. Our website is https://www.sinotainuo.com/. I look forward to your arrival very much and hope to cooperate with you.
