Q:What are the types of microbial fertilizers?
nitrogen fixation fertilizer. In the soil and many crops rhizome assimilation of nitrogen in the air, supply crop nitrogen nutrition. But also the secretion of hormones to stimulate crop growth.
Q:Fish pond water is too thin always fat up with what bio-fat
Can be applied in the fish pond organic fertilizer or phosphorus and potassium fertilizers to cultivate micro-organisms, can also be directly applied to the fishery-specific fertilizer agent. Rural areas of straw, cow dung, pig manure, weeds are also suitable for the cultivation of water, but at the same time easy to bring bacteria or parasites, should pay attention to prevention and control.
Q:Brown sugar, vegetables, water and then filial piety can make biological fertilizer do
Bio-fertilizer, the use of organic fertilizers and inorganic fertilizers, and accompanied by a variety of microbial or high-energy compounds available, very popular with farmers, the effect is more obvious, one can improve soil physical and chemical properties, enhance water retention, fertilizer performance Continuous fertilization capacity; the second is a significant inhibition of cotton, melon fusarium wilt and rice sheath blight and other diseases, enhance the resistance ...
Q:Do you have a bio - fertilizer?
Biological fertilizers in the organic raw materials if it is strictly decomposed is not burning seedlings, the root cause of burning seedlings is not decomposed organic raw materials into the soil after the microbial reproduction and metabolism of a large number of heat burns, the national standard also provides organic matter Raw materials must be wiped, but the current national standard does not detect fertilizer maturity indicators, bio-fertilizer industry quite a lot of good manufacturers in order to obtain the best interests, commonly used non-decomposed organic raw materials, such as urban sludge, Kitchen waste and other production of bio-fertilizer, so the use of bio-fertilizer in the first small batch test to test whether the fertilizer is burning seedlings.
Q:The practical significance of bio - fertilizer
the development of bio-fertilizer can reduce environmental pollution. The problem of environmental pollution caused by fertilization has been paid more and more attention. In the eutrophication of major lakes in China, the impact from agricultural pollution is even greater than that of industrial pollution. After chemical fertilizers are applied to the soil, there is a considerable part of the loss of nutrients, such as leakage, volatilization and nitrification and denitrification, which will inevitably lead to pollution to the environment, water and soil, In energy and economy is also a waste. The application of biological fertilizers such as nitrogen-fixing bio-fertilizer, not only may be appropriate to reduce the amount of chemical fertilizers (such as the application of high fertility can be reduced by 10 to 30% of the chemical nitrogen fertilizer), and because of its fixed nitrogen stored in the body, Relatively speaking, the chance of environmental pollution is much smaller.
Q:Prospects for bio - fertilizer
Bio-fertilizer production cost is low, the application effect is good, does not pollute the environment, not only after the increase in production, but also to improve the quality of agricultural products and reduce the amount of fertilizer in China's sustainable development of agriculture occupies an important position. China's growing population, people's living standards continue to improve, the quantity and quality of agricultural products put forward higher requirements. While the cultivated land is decreasing, the application rate of chemical fertilizer increases, the production cost rises linearly, the environment deteriorates and so on. These conditions provide a good development opportunity for bio-fertilizer. At the same time, the development of bio-fertilizer itself has laid the foundation for expanding the application. The world's population is soaring, and society's demand for food and fertilizer is becoming increasingly urgent. However, it is difficult to maintain the sustainable development of agriculture, and it is necessary to develop bio-fertilizers in the future because of the limited resources of the raw materials and energy sources for fertilizer production. Bio-fertilizer can not only supplement the shortage of fertilizer, and may be listed as green food and fertilizer into the commodity market, become the emerging "green industry" in agricultural production to play its due economic, social and ecological benefits.
Q:Want to open a bio-fertilizer organic fertilizer plant, what procedures are required
First registered the establishment of the company, Development and Reform Commission for the record, do EIA report, land use procedures to produce organic fertilizer but also to the soil fertilizer station testing, a temporary permit
Q:Biological fertilizer implementation standards?
Compound microbial fertilizer
Q:The role and use of terrestrial bio - fertilizer
Biomycetes are now quite mixed, if the bacteria can not reach the target or doped with harmful bacteria will lead to increased land and plant diseases. Spend money to buy real Kaopu brand. Recommended "Jin Man Tian" brand bio-fertilizer, Shandong's first specialized research bio-fertilizer research and production institutions. Shandong Vice Governor nominated technology products
Q:How is the biofeeding effect?
Bio-organic compound fertilizer is the essence of traditional organic fertilizer, combined with modern biotechnology, processing from high-tech products. Its nutrient elements are quick, long-lasting and synergistic, and have the functions of improving the quality of agricultural products, inhibiting soil-borne diseases, enhancing crop resistance and promoting crop precocity. The main features are: pollution-free and pollution-free. Bio-compound fertilizer is an effective combination of natural organic matter and biotechnology. It contains the fungicide, with the ability to accelerate the decomposition of organic matter, for the production of crops or conversion of available nutrients to provide "power." At the same time, the fungicide has the effect of improving the utilization rate of fertilizer and activating the potential nutrient in the soil.
