Q:What are the types of microbial fertilizers?
rhizobia fertilizer. Can form nodules (or stem tumors) on legumes, assimilate nitrogen in the air, supply legumes nitrogen nutrition. Manufactured by strain of Rhizobium or Rhizobium.
Q:The status quo of bio - fertilizer
popular science knowledge and application of training, the application of regional agricultural technical personnel and farmers training. To the farmers to teach the correct use of biological fertilizer knowledge, through the necessary field trials demonstration, so that the majority of farmers see their application effect. In addition, let farmers know that bio-fertilizers can not replace fertilizers and organic fertilizers, on the contrary, because the bio-fertilizer itself contains less nutrients, so no adequate application of organic fertilizer and the right fertilizer can not fully show the effect. Therefore, in the application of bio-fertilizer at the same time, must not ignore the rational use of chemical fertilizers and organic fertilizer. Of course, taking into account the biological fertilizer with nitrogen or activated soil nutrients and other characteristics, appropriate to reduce the amount of fertilizer applied, not only save production costs, but also to improve crop quality, to prevent environmental pollution is also very necessary.
Q:The characteristics of biological fertilizers
Microbial proliferation, improve crop rhizosphere ecological environment. Beneficial microbial and disease resistance factors increase, but also can significantly reduce the infection of soil-borne diseases, reduce crop disease index, successive years of application can greatly ease the continuous cropping obstacles.
Q:Prospects for bio - fertilizer
Secondly, from the perspective of sustainable agriculture, organic agriculture and ecological agriculture, the application of bio-fertilizer is promising and has huge potential market. The relationship between biological fertilizers and fertilizers is not an antagonistic relationship, and is complementary to each other. Fertilizer fertilizer effect is obvious, the role of fast, in the relative lack of agricultural areas is still necessary. But with the richness of agricultural products, the strengthening of people's environmental awareness, the need for safe agricultural products, bio-fertilizer and fertilizer will gradually grow, which is a gradual development process. And bio-fertilizer raw materials can be local materials, low cost, the ecological benefits of fertilizer can not be replaced. Therefore, the development of bio-fertilizer has a broader prospect.
Q:Biological fertilizer and chicken manure that a good one
Look for what plants, potted plants suitable for bio-fertilizer, large area, suitable for chicken manure, because chicken manure is not environmentally friendly, fertilizer effect in fact almost
Q:Anhui Tongling six countries of biological organic fertilizer prices
Biological fertilizers, also known as bio-fertilizer, bacteria fertilizer, bacterial fertilizer or inoculants, etc., but most people used to call the bacteria fertilizer. Exactly, bio-fertilizer is bacteria rather than fat, because it does not contain plant growth and development needs of nutrition Elements, but only contain a large number of microorganisms in the soil through the activities of microorganisms to improve crop nutrition conditions; organic fertilizer: mainly refers to a variety of animals and plants, after a certain period of fermentation after the formation of fertilizers. Organic fertilizer contains a large number of Biological substances, animal and plant residues, excreta, biological waste and other substances, the application of organic fertilizer can not only provide comprehensive nutrition for crops, and fertilizer effect, can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity , Is the main source of green food production. Organic fertilizer prices are generally around 500-1500 per ton.
Q:The quality of the role of bio - fertilizer
Bio-fertilizer can improve soil fertility, which is its main role, such as various nitrogen-fixing bacteria fertilizer, can increase the nitrogen source in the soil, the solution of phosphorus and potassium fertilizer can dissolve the soil insoluble phosphorus and potassium, Soil phosphorus (P), potassium (K) elements of the source. In addition, bio-fertilizers can promote crop growth and improve the quality of agricultural products. A variety of bio-fertilizer into the soil, can produce different growth hormone, stimulate the growth of crops, such as "5406" actinomycetes bio-fertilizer, not only antagonize the role of pathogens disease prevention bacteria, but also secrete cytokinin Crop growth. Fungal bio-fertilizer not only in helping crops to absorb phosphorus, zinc and copper and other mineral elements have a strong role, as well as enhance the crop of water, water to improve the role of crop drought resistance. As the bio-fertilizer can produce and help the crop to absorb the use of a variety of nutrients, so the quality of agricultural products have greatly improved, can change the fertilizer produced by the "melon is not fragrant, fruit is not sweet, tea tasteless" status, The indicators to meet the green food standards.
Q:How to use bio-fertilizer and fertilizer
Biological fertilizer can be used for seed dressing, but also as a base fertilizer and topdressing use, should be used in strict accordance with the requirements of the instructions. Biological bacteria fertilizer only after entering the soil to play a role, and the growth and reproduction have a certain carbon and nitrogen than the requirements. Therefore, the bio-fertilizer to promote early application, after application of the soil to keep moist. And organic fertilizer with the application of better results, fertilizer to reduce the nitrate content of vegetables to improve the quality of vegetables have a significant effect, can be planned to expand the use of vegetables. The main effective substances in biological fertilizers are active microorganisms. Therefore, attention should be paid to maintaining the activity of bacteria in storage and transportation applications.
Q:What is the industry of bio-fertilizer technology Co., Ltd.
August 1 began to increase the camp will expand to the country. At present, most provinces and cities in OKorder and OKorder have already reformed. Technology services provided by the technical services to pay VAT, the tax rate of 6%, if meet certain conditions, some projects can be tax-free. Enterprise income tax is only 25% of the time, but if you apply to high-tech enterprises, you can get 15% tax rate, if you can get the key software business qualification, you can enjoy 10% tax rate.
Q:Which brand of bio-fertilizer is good?
Hello, friends, now bio-fertilizer is a new fertilizer in today's society, five Fuk biological bio-fertilizer, bio-organic fertilizer, fertilizer; focus on microbial fertilizer, fertilizer, bacteria, green organic fertilizer. Can improve the soil, rooting seedlings, disease prevention, water and fertilizer, improve crop yield and quality.
