Silicon-rich organic fertilizer and preparation method thereof

Abstract

The invention discloses a silicon-rich organic fertilizer and a preparation method thereof. The silicon-rich organic fertilizer comprises, by weight, 5-8 parts of diatomite, 5-10 parts of straws, 20-40 parts of Equisetum ramosissimum, 3-8 parts of corncobs, 10-20 parts of bean stalks, 5-7 parts of EDTA, 3-5 parts of calcium superphosphate and 0.5-0.8 parts of a fermentation inoculant. The microbial aerobic fermentation allows abundant silicon element in the straws, the Equisetum ramosissimum and the corncob raw materials to be converted into water-soluble effective silicon which can be easily absorbed by plants. Diatomite in the organosilicon fertilizer has porousness and extremely physical adsorption and ion exchange performance, and is a good soil improver. The silicon fertilizer is applied to make crops have the advantages of strong disease resistance, high output and high silicon content.

Description

technical field [0001] The invention belongs to the field of fertilizers and provides a silicon-rich organic fertilizer suitable for crops. Background technique [0002] Silicon is the second most abundant element in the earth's crust and soil, and its content is second only to oxygen. It mostly exists in the form of silicate crystals or precipitation, and the effective silicon content that can be absorbed and utilized by plants is relatively low. Silicon is an indispensable trace element to maintain the normal life activities of the human body. The human body absorbs silicon mainly through the conversion of silicon in food. After food containing silicon enters the digestive tract, it is easily absorbed by the intestinal wall and transported to the whole body through lymph and blood. various organizations. Silicon has positive effects on plant growth such as stress resistance. Studies have shown that silicon can improve rice quality, yield, lodging resistance and heavy meta...

[0005] Chinese Patent No. CN200910012060.4 discloses a method for preparing silicon fertilizer from fly ash containing silicon dioxide. This method has the advantages of realizing waste recycling and environmental protection, but the preparation process is complicated, and the silicon dioxide in fly ash has It is difficult to dissolve in water, so it is difficult to quickly transform and be absorbed by plants, thus affecting the silicon-rich effect of crops

The ecological silicon fertilizer provides silicon to crops through biological silicon particles, but excessive application of washing powder in the silicon fertilizer will easily cause soil and water pollution, which is not conducive to ecological balance
