Compound microbial fertilizer special for paddy rice and preparation method of fertilizer

Abstract

The invention provides a compound microbial fertilizer special for paddy rice and a preparation method of the fertilizer. The compound microbial fertilizer is made from an organic fertilizer component, an inorganic fertilizer component, a compound microbial agent and a coating material, wherein the coating material is composed of medium chain triglyceride, a solid phase component, and an aqueous phase component. Through effective combination of organic, inorganic and microbial components, the fertilizer is abundant in organic matter components, inorganic nutrients and effective active bacteria. The fertilizer has a good yield-increasing effect-improving function, is good in slow release effect, and has a better anti-disease effect.

Description

technical field [0001] The invention relates to the technical field of agricultural microbial fertilizers, in particular to a special compound microbial fertilizer for rice and a preparation method thereof. Background technique [0002] Nearly half of the population in the world feeds on rice, which is processed from rice, and rice bears seeds that are paddy rice, which is called brown rice after the chaff is removed, and rice can be obtained by grinding the rice bran layer off the brown rice. The robustness of rice seedlings is the basis for increasing production, and the timely supply of nutrients during the growth of rice seedlings is particularly important. With the continuous growth of food demand, the use of fertilizers in agricultural production generally shows an increasing trend. However, the fertilizers currently on the market have the following problems: [0003] 1. The utilization rate is generally low, and various components that are not used by plants in time ...

AI Technical Summary

Problems solved by technology

[0003] 1. The utilization rate is generally low, and various components that are not used by plants in time will infiltrate into the soil, which will cause eutrophication of surrounding rivers and lakes, etc., leading to the deterioration of people's living environment

[0004] 2. Multiple applications are required, and the fertilizer effect is short and low

[0005] 3. Most of the special fertilizers for rice on the market are inorganic fertilizers, which can meet the growth needs of rice in a short period of time, but long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening; Some simple organic fertilizers are used. Although rich in organic matter, the release of nutrients is slow, the absorption of rice is slow, and the fertilizer efficiency is low.
