Biological water flushing fertilizer and preparation method thereof

Abstract

The invention provides a biological water flushing fertilizer. The biological water flushing fertilizer is prepared by mixing a microorganism strain and an organic fertilizer, wherein the microorganism strain is obtained by carrying out strain liquid fermentation on bacillus subtilis, brevibacillus laterosporu and bacillus mucilaginosus; the biological water flushing fertilizer is composed of the following components in percentage by mass: 10%-20% of the microorganism strain, 20%-30% of humic acid, 30%-60% of calcium nitrate or phosphorus nitrate, 5%-10% of boric acid, 5%-12% of magnesium sulfate, 5%-8% of ferrous sulfate, 1.5%-5% of organic matters, 2%-6% of sulfur powder, 0.5%-1.0% of bentonite and 1%-5% of an inductive agent. The preparation method comprises the following steps: liquid fermentation of the strain, adsorption of fermented strain liquid, and preparation of the biological water flushing fertilizer. According to the biological water flushing fertilizer, the nutritional value of fertilizer raw materials is obviously improved and the fertilizer effect is rapidly improved; the fertilizer utilization efficiency effect and the effect of preventing diseases and increasing the output are improved. Meanwhile, the soil physical and chemical properties are also improved; the hardening is eliminated, the soil is loosened, the pH value of the soil is adjusted and the soil structure is improved.

Description

technical field

[0001] The invention relates to fertilizer production technology, in particular to a biological flushing fertilizer and a preparation method thereof. Background technique

[0002] Fertilizer occupies a very important position in my country's grain production. The fertilizers currently on the market can be classified into two categories, one is chemical fertilizers, and the other is compound fertilizers that combine chemical fertilizers and organic fertilizers. Long-term use of chemical fertilizers will reduce soil fertility, reduce fertilizer utilization, destroy soil structure, and cause soil compaction. In addition to nitrogen, phosphorus, potassium and trace elements, compound fertilizer also contains organic matter. The central purpose of these fertilizers is to provide comprehensive chemical elements, but no consideration is given to improving the micro-organisms and micro-nutrient structure in the soil environment.
