Rice special composite microbial fertilizer and preparation method thereof

Abstract

The invention belongs to the field of microbial fertilizers, and particularly relates to a rice specific composite microbial fertilizer, a preparation method and an application thereof. The rice composite microbial fertilizer is prepared from the following raw materials: 25-40 parts of an organic fertilizer, 5-10 parts of a nitrogen fertilizer, 4-8 parts of a phosphate fertilizer, 3-6 parts of a potassium fertilizer, 1-5 parts of trace elements, 12-35 parts of a composite microbial fertilizer inocula, and 3-10 parts of compound microbial pesticide inocula. The method adopts a microbial fertilizer technology and a microbial pesticide technology, the rice compound microbial fertilizer is prepared by a high-efficiency preparation process, the fertilizer is uniformly applied in the rice fieldbefore the rice seedling transplanting, the waterflooding treatment is carried out for 1 to 4 weeks, the soil fertility can be effectively improved, the use of inorganic fertilizers is reduced, and the soil environment of rice fields is improved, at the same time, the fertilizer can improve plant growth rate and quality, enhances rice resistance, reduces the occurrence of rice diseases, and increases yield increase and income increase.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a compound microbial fertilizer for rice and its preparation method and application. Background technique [0002] Rice is one of the most important food crops in the world, and more than half of the world's population feeds on rice. Rice planting area accounts for about 20% of the world's total grain planting area. With the continuous growth of food demand, the use of fertilizers in agricultural production generally shows an increasing trend, while the utilization rate of fertilizers in my country is only about 30%. At the same time, blindly increasing and partial application of chemical fertilizers not only increases the cost, but also destroys the soil structure, nutrient balance and microbial diversity, resulting in poor growth of rice, difficulty in improving yield, and decline in rice quality. In particular, frequent rice diseases have seriously affected fa...

AI Technical Summary

Problems solved by technology

Organic fertilizers have a longer fertilizer effect, can increase and renew soil organic matter, improve soil physical and chemical properties and biological activity; microbial fertilizers can increase the number of beneficial microorganisms in the soil, and strengthen crops' absorption and utilization of soil water and nutrients, but these fertilizers are not very effective. Well solve the problem of soil nutrient balance and rice healthy growth
