Biofertilizer capable of decomposing insoluble phosphorus and preparation method

Abstract

The invention discloses a fermented fertilizer capable of decomposing insoluble phosphorous and a preparation method of the fermented fertilizer. The fermented fertilizer is composed of shale or mountain soil, dry chicken manure, bone meal, fish scrap, bean cake, starch or brown sugar, and enzyme bacteria according to a certain ratio. The preparation method comprises the steps of: A. preparing raw materials: preparing shale or mountain soil, dry chicken manure, bone meal, fish scrap, bean cake, starch or brown sugar, enzyme bacteria and water; B. mixing: dissolving brown sugar or starch with water, spraying to a mixture of shale or mountain soil, dry chicken manure, bone meal, fish scrap, bean cake and enzyme bacteria, mixing and stirring uniformly, adjusting the moisture content to 40-45%, stacking into a chevron, and covering with ventilating cloth; C. overturning: beginning overturning after 48h of the production day or the temperature in the stack is more than 50 DEG C, and then overturning 1-2 times every day; D. fermenting: finishing fermentation within 7d; E. drying: spraying on cement land at a thickness of 15cm, and airing; F. inspecting; and G; packaging. According to the Biofertilizer provided by the invention, fermentation microorganisms are used for decomposing water-insoluble phosphorus into water-soluble phosphorus, thereby being beneficial to crop absorption, saving resources and protecting environment.

Description

technical field [0001] The invention belongs to the technical field of biological agriculture, and more specifically relates to a biological fertilizer that can decompose insoluble phosphorus, and also relates to a preparation method of a biological fertilizer that can decompose insoluble phosphorus, which is applied to the decomposition of fermented microorganisms in agricultural production. It can decompose non-water-soluble phosphorus (animal bone meal, insoluble phosphorus in soil, etc.) into water-soluble phosphorus, so as to facilitate crop absorption and increase crop yield. The bio-fertilizer is a high-efficiency and environment-friendly field bio-fertilizer, which is suitable for various field crops, gardening, tree planting, etc. Background technique [0002] In our country and even in the world, the phosphorus element in fertilizers has always come from limited phosphate rock resources. Due to the food problem for the survival of a large number of people, the limi...

Problems solved by technology

[0007] Since most of them use organic materials as raw materials, they do not have the function of dissolving phosphorus, nor can they provide sufficient phosphorus.
