Over the years, in the cultivation of crops, the amount of chemical fertilizers has been increasing, the amount of organic fertilizers has been decreasing, and the utilization rate of chemical fertilizers by crops is only about 30%, and about 70% of chemical fertilizers are fixed in the soil. Or the rainwater is lost in the rivers without being absorbed and utilized by the crops, which causes soil compaction, environmental pollution, eutrophication of rivers and groundwaters, soil organic matter content, fertility decline, and the living space of beneficial microorganisms in the soil becomes smaller. The number is reduced, the disease resistance, cold resistance and drought resistance of crops are weakened, and the occurrence of pests and diseases is becoming more and more serious, resulting in a decline in the quality of crops and a decrease in yield.
The application of compound microbial fertilizers on crops can not only improve the effective utilization rate of chemical fertilizers, but also increase the fertilizer utilization rate by 10%-30%. The application test shows that: Bacillus subtilis, Bacillus licheniformis, Bacillus thermophilus production The compound microbial fertilizer has been used continuously for more than two years. The number of beneficial actinomycetes in the soil has increased by 8.4 times, and the nitrogen-fixing bacteria has increased by 39 times, thereby achieving the effects of activation, vegetable pine soil, soil fertility enhancement, and mass reproduction of beneficial microbial bacteria. After years of chemical fertilizers fixed in the soil, they are once again used for absorption and utilization by crops. At the same time, the increase of the number of Bacillus licheniformis in the soil can effectively control the soil pathogenic bacteria and root-knot nematode, and the prevention rate can be as high as 70-80%, which is equivalent to the chemical pesticide control effect. Thereby reducing the amount of chemical pesticides used, improving the quality and yield of crops and the ability to resist heavy mites.
In recent years, the application of bio-organic fertilizers and compound microbial fertilizers has become more and more widespread, especially the rapid rise of compound microbial fertilizers, which will make China's fertilizer industry enter a new era. The application of compound microbial fertilizers in agricultural production shows that the utilization of chemical fertilizers The improvement, loosening the soil, reducing river pollution, fertilizing soil fertility, reducing the occurrence of pests and diseases, and enhancing the stress resistance of crops have very good effects.
Focus: The relationship between chemical fertilizers, organic fertilizers and microbial fertilizers:
For a long time, some companies or technicians engaged in chemical fertilizers, organic fertilizers, and microbial fertilizers have always been in their own industry to compare the three, who is better than anyone else. In fact, chemical fertilizers, organic fertilizers, and microorganisms in agricultural production. There is no comparability between the fertilizers. There is no question of who replaces them. The relationship between them is like the complementarity between fish, vegetables and fruits on the table of people, complementing each other, and the compound microbial fertilizer is sufficient. The land organically combines the three to play the role of 1+1+1>3.
Functional characteristics of compound microbial fertilizer:
Fully nutritious: not only provides the required NPK and medium and trace elements for crop growth, but also provides organic and beneficial microbial active bacteria for crops.
The fertilizer effect has the effect of slow release, and improves the utilization rate of fertilizer: in the production process, some inorganic nutrients are dissolved and organically adsorbed and combined to form an organic NPK, which is not easily lost and fixed into the soil, and the chemical fertilizer utilization rate can be Increase by 10-30%, fertilizer efficiency can last 3-4 months.
Loose soil, dissolve phosphorus and potassium, and fertilize soil: After the fertilizer enters the soil, the microorganisms multiply with the help of organic matter, inorganic nutrients, water and temperature, which reduces the living space of the harmful microbial population, thereby increasing the soil beneficial microbial bacteria. The amount of microbial bacteria producing a large amount of organic acids can partially dissolve the phosphorus and potassium elements deposited in the soil for many years to be re-absorbed and used. After long-term use, the soil will become more and more loose and fertile.
The disease-preventing, insect-repellent and anti-heavy micro-organisms are dormant in the fertilizer. After entering the soil for germination and reproduction, a large amount of chitinase, extracellular enzymes and antibiotics are secreted, which can effectively lyse the spore wall of the harmful fungus, the nematode egg wall and It inhibits the growth of harmful bacteria, effectively controls the occurrence of soil-borne pests and diseases, and plays a role in preventing disease, preventing insects and resisting heavy mites.
Rooting and strong seedlings, reducing nitrite content, improving quality, increasing yield and increasing income After the microbial bacteria multiply in the soil, they produce a large amount of plant hormones and organic acids, stimulate root growth and development, enhance the photosynthesis intensity of crops, and the roots of crops are deep and leafy. Effectively increase the sugar content of crop fruits, reduce the content of nitrates and other harmful substances in crop products, improve quality, and increase crop yield by 10-30%.
Accelerating the degradation of organic matter in the soil not only provides more organic nutrients for crop growth, but also improves the stress resistance of crops; it also reduces the living space of some pathogenic bacteria in the soil.
Prospects:
According to Zhou Zeyu, director of the Technology Promotion Department of the National Agricultural Technology Promotion Center of the Ministry of Agriculture, the demand for bio-fertilizer will reach 45 million tons in the next 5-10 years, especially if the compound microbial fertilizer is pushed away quickly, the market will be large.
Huang Weiyi, a professor at Nanjing Agricultural University, believes that the combination of organic fertilizer, biological fertilizer and inorganic fertilizer has significant synergistic complementation effects.
Zhou Fayong, a researcher at the Chinese Academy of Agricultural Sciences, defines compound microbial fertilizer as a third-generation bio-fertilizer with a comprehensive function of “three-in-one†for nutrition, conditioning and plant protection.
Li Jun, director of the Quality Supervision and Testing Center for Microbial Fertilizers and Edible Fungi, of the Ministry of Agriculture, said that the compound microbial fertilizer consists of functional bacteria, organic matter and NPK, achieving “a quick fertilizer, long-term organic fertilizer, and microbial fertilizers to promote and transformâ€. The comprehensive effect has broad application prospects.
Li Jun explained that practice has proved that it is very difficult to simply promote organic fertilizer and microbial fertilizer, and that compound microbial fertilizer combines scientific, rationality and acceptability best, which not only meets the needs of agricultural production, but also conforms to the fertilizer of farmers. Habits can also be accepted by enterprises and markets in terms of price, while also ensuring the ecological protection goals pursued by the government.
Therefore, Li Jun once suggested that the compound microbial fertilizer be called “whole yuan biological fertilizerâ€.
It is understood that there are currently 950 registered enterprises in the bio-fertilizer industry, with an annual output of about 10 million tons. As of September this year, the total number of product registrations was 2,299, and the application area of ​​bio-fertilizers exceeded 200 million mu, which has become a part of the bio-industry and bio-economy. Important force.
Compound microbial fertilizer in biological fertilizer
The compound microbial fertilizer organically combines inorganic nutrient elements, organic matter and microbial bacteria, and reflects the comprehensive effects of inorganic chemical fertilizers, organic fertilizers and microbial fertilizers, which is to resolve soil compaction, repair and regulate soil, improve chemical fertilizer utilization, and reduce rivers and rivers. Pollution, reduce the occurrence of pests and diseases, enhance the resilience of crops, and improve the quality of crops and the preferred fertilizer for yield.
