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 ability to resist; third is to improve the quality of crops, especially for watermelon, sugar cane, strawberry and other fruits Sweetness is very obvious; four is to promote crop yield, the general application of bio-organic compound fertilizer than a single application of fertilizer yield of about 10%; five is to reduce the agricultural environment pollution, can produce a large number of pollution-free food. Can produce bio-fertilizer material is very much, such as livestock and poultry manure, bad slag, silt,
Q:How is the biofeeding effect?
The effect is good

Its product implementation standards: organic fertilizer NY525-2002, organic - inorganic compound fertilizer GB18877-2002, bio-organic fertilizer NY884-2004. Other products that do not meet the above criteria are not included in the financial and taxation [2008] 56 document of organic fertilizer products, should be in accordance with the existing provisions of the collection of value-added tax.
Q:What are the benefits of biological fertilizers?
to reduce the use of fertilizer and improve crop quality After the use of microbial fertilizer to improve the quality of agricultural products, such as protein, sugar, vitamins and other content on a certain role, and some can be reduced
Q:The practical significance of bio - fertilizer
Bio-fertilizers effectively utilize nitrogen or soil nutrients in the atmosphere. Therefore, the development and use of nitrogen-fixing biological resources is an important aspect of making full use of nitrogen in the air. In addition, the crop on the soil phosphorus, potassium and other mineral nutrient use capacity is poor, and phosphorus, potassium and other fertilizer utilization is also low, phosphate fertilizer season crop utilization rate of less than 20%, potash crop utilization The rate is generally below 40%. In the case of China, there is a serious shortage of phosphorus and potassium resources, especially because the potash is heavily dependent on imports. Therefore, how to convert the ineffective phosphorus and potassium in the soil into available nutrients for crop absorption and utilization, Concern, the application of biological fertilizers, no doubt to provide a prerequisite for it.
Q:Brown sugar, vegetables, water and then filial piety can make biological fertilizer do

Q:Prospects for bio - fertilizer
First of all, the development of green food industry is an urgent need for bio-fertilizer. Application of bio - fertilizer to promote the transformation of traditional organic fertilizer to fertilizer technology. Traditional organic fertilizer accumulation method is relatively backward, generally the continuation of the "circle, pit retting, people pick, Mara" production habits. Organic fertilizer production and use must be to the factory, professional, commercial direction, otherwise, organic fertilizer industry will shrink, is not conducive to the development of sustainable agriculture. The application of biological fertilizer (organic fertilizer starter) can greatly shorten the time of organic fertilizer fermentation, which is conducive to the industrial production of organic fertilizer, so that organic fertilizer to the direction of commercial development. Long-term application of bio-organic fertilizer can fertilize the soil, purify the crop growth environment, for the sustainable development of agriculture to create the conditions. With the continuous development of economy, people's living standards continue to improve, people's food quality requirements more stringent, the application of bio-fertilizer to reduce the amount of fertilizer, agricultural products can reduce the nitrate content, improve the quality of agricultural products, and effectively solve the agricultural products harmful substances exceeded Problem, so that agricultural products become a real green food.
