A kind of special compound microbial fertilizer for rice and preparation method thereof

Abstract

The invention provides a special compound microbial fertilizer for paddy rice. The compound microbial fertilizer comprises the following components: an organic fertilizer component, an inorganic compound fertilizer component, bentonite and a compound microbial component; the compound microbial fertilizer contains 10-15% of nitrogen, 4-8% of phosphorus, 6-10% of potassium, 25% of organic matters and 2-18 hundred million c f u / g of compound microorganisms. According to the invention, comprehensive nutrition required by the growth of the paddy rice can be met; the quality of the paddy rice is improved and the increase in both yield and income is realized; moreover, the soil fertility of the rice field can be improved, the soil environment of the rice field is improved, and the occurrence of rice diseases is effectively prevented.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special compound microbial fertilizer for rice and a preparation method thereof. Background technique [0002] At present, due to the long-term and large-scale use of chemical fertilizers in my country, soil compaction, soil fertility decline, groundwater pollution, biological activity decline, soil organic matter content is extremely low, and the quality of agricultural products has declined. In order to solve this problem, there are various types of fertilizers on the market, such as organic-inorganic compound fertilizers, organic compound fertilizers, and microbial fertilizers. Organic fertilizers have a longer fertilizer effect, can increase and renew soil organic matter, and improve soil physical and chemical properties and biological activity. Microbial fertilizer can increase the number of beneficial microorganisms in the soil, and enhance the absorption and util...

Problems solved by technology

However, due to the long-term emphasis on yield and unreasonable use of chemical fertilizers and chemical pesticides in rice production, the existing rice planting model has been greatly affected, soil fertility has declined, and the quality and safety of rice products have also attracted much attention.

[0004] At present, there are many organic fertilizers and microbial fertilizers applied to rice. Organic fertilizers and microbial fertilizers can effectively improve the soil environment and increase soil fertility. However, the nutritional components of pure organic fertilizers and microbial fertilizers are not very comprehensive, and a large amount of inorganic Fat to use with

Also have many companies to be researching organic and inorganic biological fertilizer now, as the invention patent of CN102701884A of Chinese Patent Publication No., disclose a kind of biological compound fertilizer containing organic and inorganic components and its preparation method, this product nutritional labeling is more comprehensive and sufficient, but In the actual production process, the loss of microorganisms is relatively large, and it is not easy to preserve, the content of effective bacteria is too low, and the effect is limited.
