A kind of composite organic microbial bacterial fertilizer and its manufacturing method

Abstract

The invention discloses a composite organic microbial fertilizer and a preparation method for the same. The composite organic microbial fertilizer comprises 5-30 parts by weight of humic acid, 10-30 parts by weight of crop straw carbon or 20-30 parts by weight of rice husk meal, and 10-30 parts by weight of animal waste. The preparation method comprises the following steps of: crushing the crop straw carbon or rice husk meal to be 80-100 meshes, crushing the humic acid to be 80-100 meshes, and drying and sterilizing the animal waste by heating, and mixing the materials in the proportioning ratio aforementioned, and using the mixture as a carrier material for the future use; and taking 3-5 parts by weight of mixed biological agent, uniformly mixing and stirring the mixed biological agent with 800-900 parts by weight of the standby carrier material, adjusting the humidity to be 20-30%, placing in a pit and hermetically fermenting for 48-60 hours at a temperature of 10-50 DEG C, taking out and granulating under a water content of less than 18%. The fertilizer is remarkable in the effects of suppressing soil-borne disease and promoting growth on continuous cropping fields of facility strawberry and the like, and achieves a yield increasing rate of 10-30%; and blossoming and fruit yielding are advanced, and the yield increasing rate achieves 10-30%.

Description

technical field [0001] The invention relates to a fertilizer and a production process of the fertilizer, that is, a composite organic microbial bacterial fertilizer and a manufacturing method thereof. Background technique [0002] The role of biology in agriculture has been gradually recognized by people. At present, more than 70 countries in the world have produced, applied and promoted microbial fertilizers. At present, there are 250 enterprises in my country with an annual output of about hundreds of thousands of tons of microbial fertilizers used in production. Although this cannot be compared with the output and amount of chemical fertilizers in the same period, it has indeed begun to play a role in agricultural production, and has achieved certain economic and social effects, and has initially formed a formal industrial production stage. With the deepening of research and the need to continuously expand the development of new varieties, microbial fertilizers have now ...

Problems solved by technology

Some bacterial fertilizers have many strains, but carrier materials are hard to come by

For example, many bacterial fertilizers use coal gangue as a carbon source carrier, but their auxiliary nitrogen source carriers are limited to wheat bran, chicken manure, etc., with few sources, and it is difficult to meet the needs of agricultural production.
