Organic fertilizer for improving acidic soil and preparation method thereof

Abstract

The invention relates to organic fertilizer for improving acidic soil and a preparation method thereof and belongs to the field of means of production for soil improvement in the field of agriculturalproduction. The organic fertilizer is characterized by being prepared through mixing the following components in percentage by weight: 50 to 80 percent of organic material, 10 to 20 percent of potassium feldspar powder, 8 to 30 percent of calcium polysulfide and 1 to 10 percent of gamma-polyglutamic acid; a production scheme comprises the following steps: putting the organic material and the potassium feldspar powder into a mixing machine and uniformly stirring; then slowly adding calcium polysulfide and gamma-polyglutamic acid and stirring and mixing; preparing a powder product and directlypackaging; or granulating, drying and processing to obtain granular organic fertilizer. The product provided by the invention can provide potassium, calcium and a soil protection agent to the soil when the acidic soil is cultivated and fertilized; the PH (Potential of Hydrogen) value of the soil is improved, the permeability of the soil is improved and the content of organic matters in the soil isimproved. The advantages of all the components are comprehensively utilized, the product is simple to produce and the acidic soil is rapidly improved; comprehensive nutrients are provided for the growth of crops.

Description

technical field [0001] The invention relates to an organic fertilizer for improving acidic soil and a preparation method thereof, belonging to an agricultural production means for improving and repairing soil in the field of agricultural production. Background technique [0002] Acidic soil is the general term for soil with a pH value less than 7. Including brick red soil, red soil, red soil, yellow soil and dry red soil and other soil types. In the tropical and subtropical regions of my country, there are widely distributed acidic soils with various red or yellow soils. The local temperature is high and the rainfall is heavy, with the annual rainfall mostly above 1500mm. The characteristics of high temperature, rainy season, and hot and humid seasons make the weathering and pedogenesis of the soil very strong, and the cycle of biological matter is very rapid. The base is highly unsaturated and the pH is generally 4.5-6. At the same time, iron and aluminum oxides are obv...
