Problems solved by technology

In addition, due to the use of chemical fertilizers and pesticides by humans, the beneficial bacteria in the soil have been severely damaged, and soil fertility has degraded. If more chemical fertilizers and pesticides are applied year after year, there will be no good harvests.

preparation example Construction

[0033] According to one aspect of the present invention, the present invention also relates to the preparation method of the above-mentioned microbial granular fertilizer, comprising:

[0034] Grind soluble potassium salt and / or sulfate minerals into powder, mix with microbial bacteria powder and coagulant, add water to form a paste, mix well, granulate and then dry.

[0035] Preferably, the above-mentioned preparation method of microbial granular fertilizer, the granulation is carried out below 60°C;

[0036] Optionally, the temperature of the granulation is 0°C to 50°C; 4°C to 40°C, or 6°C, 10°C, 20°C, and 30°C can also be selected.

[0037] The coagulant used in the present invention is liquid silica gel, which is often exothermic during solidification. The adsorption heat of silica gel often increases the temperature, so it is necessary to try to cool it.

[0038] Lower temperature can prevent microorganisms from dying during coagulation and granulation.

[0039] Prefera...

Abstract

The invention relates to the field of fertilizers, in particular to a microbial granular fertilizer and a preparation method thereof. The microbial granular fertilizer comprises, by weight, 3-8 partsof microbial flora powder, 7-15 parts of soluble potassium salt and / or sulfate minerals and 3-5 parts of coagulators. The microbial granular fertilizer can rapidly build microbial profitable strains and improve crop yield.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a microbial granular fertilizer and a preparation method thereof. Background technique [0002] In the modern agricultural production system, due to the limited amount of mineral nutrients that the cultivated soil can provide for crops to absorb during the growing season of crops, it is one of the fundamental measures to ensure crop yields to provide an appropriate amount of mineral nutrients to crops through fertilization. Tens of millions of tons of fertilizers are applied to farmland globally each year. [0003] Chemical fertilizers have laid a material foundation for the production and development of modern agriculture and ensuring human food security. However, the low utilization rate of chemical fertilizers and the resulting high environmental risks have always been a major problem plaguing the world. Therefore, all countries in the world are actively exploring methods and appro...
