Q:Shaanxi hundred generations of cocoa fertilizer bacteria bacteria bio-fertilizer why is wet?
Any factory can produce organic fertilizer can not be wet, which does not meet the production standards, is not conducive to organic fertilizer to save, you can contact the manufacturers, if you really have to produce it is wet, basically do not fly
Q:Do you want to make bio - fat
However, the production of bio-fertilizer is not just a biological carrier can be made, the need for a variety of beneficial bacteria, which is good for the crop of microorganisms to fermentation, You can buy some fermented bacteria with bacteria slag used to ferment the fermentation.
Q:Can bio - fertilizer replace organic fertilizer?
One of the views that it is highly efficient, as it can be fertile, and even threatened to completely replace the fertilizer; another view that it is not fertilizer. In fact, these two are biased. The rational application of bacteria fertilizer seed dressing or the application of microbial fertilizer, crop yield increase effect, but also the benefits of fertilizer can not reach. Therefore, we think it is fertilizer, but also with the traditional fertilizer and organic fertilizer from the concept or connotation are different.
Q:How about the effect of halving the biological fertilizer?
The use of fertilizer by half the amount of fertilizer with half the amount, and the effect is still very good, is a good product, like a ~
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:The status quo of bio - fertilizer
Production enterprises must continue to improve the production conditions, formula, technology, equipment, improve the quality of workers. Pay attention to the on-the-job training of employees, cooperate with institutions of higher learning, cooperate with the Institute of Agricultural Sciences to improve the comprehensive strength of enterprises, strengthen basic research efforts, develop product quality standards and produce stable high quality products.
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:Biological fertilizer implementation standards?
NY 411-2000 Nitrogen fixation fertilizer
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.
Q:How is the biofeeding effect?
Bio-organic fertilizer mechanism and effect of the main features of bio-organic fertilizer: containing microbial flora, bacteria adapt to the environment, easy to play the advantages of flora, nutritional function, rhizosphere promotion effect is good, high fertilizer. Rich in organic nutrients, inorganic nutrients, small size, easy to use, to meet the requirements of large-scale production. Rich in physiologically active substances. Safe and harmless Bio-organic fertilizer fertilizer mechanism of organic fertilizer fertilizer efficiency is beneficial microbial fertilizer efficiency, efficient organic fertilizer fertilizer effect generated by the interaction. 1. Improve the soil structure Organic fertilizer is the best soil improver, can promote the formation of soil aggregate structure, improve the physical shape of the soil, mainly due to increased non-capillary porosity, large water stable aggregates increased in improving the soil structure At the same time, the permeability of the soil ventilation enhanced. 2. increase the soil nutrients organic fertilizer contains nutrients necessary for nutrient growth, nutrient characteristics of a large amount of organic matter adsorption, nutrient is not easy to lose, the second is nutrient complete, easy to break down, easily absorbed by crops. Application of organic fertilizer not only to add the soil nutrients, while the nutrient cycle from the perspective of the nutrients absorbed from the soil to be recycled to reduce the deficit of soil nutrients. Organic fertilizer in the addition of nutrients at the same time, but also the activation of soil nutrients, organic fertilizer decomposition of organic acids or some organic groups with iron, aluminum chelate or complexation, reduce soil fixation of phosphorus; organic fertilizer decomposition, especially Decomposition under flooding conditions can improve the soil reducibility, so that iron and aluminum are reduced and increase the solubility of phosphorus
