Subacidity organic fertilizer for rice planting and preparation method thereof

Abstract

The invention discloses a subacidity organic fertilizer for rice planting. Raw materials of the subacidity organic fertilizer comprises animal faeces, rice hull ash, a subacidity auxiliary, seaweed powder, brown rice residues, soybean straw, ferric citrate, ferrous sulfate, potassium chloride, ammonium dihydrogen phosphate, ammonium chloride, sulfuric acid, urea formaldehyde, zinc sulfate, urea, potassium nitrate, ferrous sulfate, calcium superphosphate, copper sulfate, water-soluble silicon, potassium humate, coal dust, perlite, coconut shell flour, lignin, EM fungicide, a modified adhesive and a modified controlled release formulation. The invention further discloses a preparation method of the slightly acid organic fertilizer for rice planting. According to the invention, the prepared slightly acid organic fertilizer for rice planting can provide rich nutrient substances for each stage of rice growth, is high in release efficiency of the nutrient substances, can improve alkalinity and acidity of rice planting soil, provides a more suitable growth pH value for rice and effectively improves yield and quality of rice.

Description

technical field [0001] The invention relates to the technical field of rice planting fertilizers, in particular to a slightly acidic organic fertilizer for rice planting and a preparation method thereof. Background technique [0002] Rice is the main food crop in my country. Rice is generally planted in multiple stubbles. The organic and inorganic fertilizers applied to the planting soil will cause the planting soil to become alkaline. However, the pH requirement of rice to the planting soil is 6-7, which is weakly acidic. However, most of the current rice planting areas cannot meet this requirement, and most of the organic fertilizers currently on the market are weakly alkaline, and the slow-release performance of nutrients cannot meet the actual needs of rice planting, resulting in reduced rice production and poor quality. Therefore, there is an urgent need to design a kind of slightly acidic organic fertilizer for rice cultivation to solve the problems in the prior art. C...
