Problems solved by technology

However, for microbial fertilizers, there are certain shortcomings in the selection of these materials: (1) the water solubility of the materials is poor, so the effect of dissolving the fertilizer in water after coating is poor, and the solution is turbid; (2) it has a stimulating effect on microorganisms and the survival rate is low; (3) ) The cost is high; (4) The coating is uneven, and there are bumps on the surface of the fertilizer
[0005] Foreign coated fertilizers have been produced and applied for many years, but the price of coated materials is generally 2 to 3 times higher than that of conventional fertilizers due to the complexity of the coating materials used or the production process, so that most of the coated fertilizers are only used in areas with relatively high economic value. In the production of high flowers, vegetables, turf, etc.

Abstract

The invention provides hardening-preventing microorganism coated fertilizer. The hardening-preventing microorganism coated fertilizer comprises a hardening preventing agent, compound fertilizer and a coating agent; the weight ratio of the hardening preventing agent, the compound fertilizer and the coating agent is (20 to 50) to (2000 to 4000) to (40 to 80); the hardening preventing agent comprises hardening preventing oil, carbon powder, urea and potassium humate; the coating agent comprises feather protein powder, mountain flour and fungicide and is used for improving disease resistance of crops and the yield of crops.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to an anti-hardening microbial coated fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an important means of production for increasing crop yield and harvest. In recent decades, due to the widespread application of chemical fertilizers, my country's grain production has doubled. However, the long-term partial application of chemical fertilizers in farmland has deteriorated the soil structure, unbalanced nutrients, and drastically reduced microbial populations, resulting in low fertilizer use efficiency and a decline in the quality of agricultural products. [0003] Applying biotechnology to develop and develop microbial fertilizers is one of the needs and choices for the sustainable development of modern agriculture. It has a history of nearly 50 years in China. It can not only fix the nitrogen in the atmosphere, dissolve the fixed mi...
