Acid soil regulator with plant nutrient function and preparation method thereof

Abstract

The invention relates to an acid soil regulator with a plant nutrient function and a preparation method thereof. The acid soil regulator is prepared by uniformly mixing basic materials and auxiliary materials, wherein the basic materials are prepared by mixing and fermenting brewer's grains, peat soil, traditional Chinese medicine dregs, soybean meal powder, straw powder, edible fungi dregs, pineapple paste, apple paste, silkworm excrement, proteolytic enzyme, nitrogen-immobilizing bacteria, rhizobium, potassium-decomposing bacteria, cellulose decomposing bacteria, antibiotic producing bacteria and water; the auxiliary materials are prepared by uniformly mixing earthworm manure, charcoal residues, urea, plant ash, lime powder, urea iron complex, and chelated zinc. The preparation method comprises the following steps of A, preparation of the basic materials; B, preparation of the auxiliary materials; C, preparation of the soil regulator. The acid soil regulator has the advantages that multiple rich and absorbable nutrients are provided for the plant growth, the problem of soil caking is effectively solved, the air ventilating property of the soil is improved, the acidity of the soilis reduced, and the fertilizer-maintaining and water-maintaining ability of the soil is enhanced. The preparation method has the advantages that the preparation method is simple, the implementing iseasy, the investment cost is low, and the preparation method is suitable for large-area popularizing.

Description

Technical field [0001] The invention relates to the field of planting, in particular to a fertilizer and a preparation method thereof. Background technique [0002] Due to factors such as soil composition, planting patterns, fertilization, climate, etc., there are many acidic soils in my country, most of which have a pH value of less than 5.5, and some are even lower. Due to years of continuous cropping and excessive application of chemical fertilizers, soil acidification has become more and more serious, which has become a major limiting factor in achieving safe food production and sustainable development. In addition, with the unreasonable large-scale application of inorganic chemical fertilizers and the increase in acid deposition caused by acid gas emissions, the area of ​​acidified soil has increased year by year, and the degree of soil acidification has been significantly accelerated. [0003] The traditional method of improving soil acidification is liming. Although the a...

Problems solved by technology

Although the application of lime can alleviate the degree of soil acidification within a certain range, due to the low mobility of lime in the soil, long-term and excessive application of lime will cause compaction of the surface soil, and excessive effective nutrients will be calcified and cannot be absorbed by crops. cause nutritional imbalance

[0004] Existing soil conditioners have certain significance for solving soil compaction, alleviating soil saline-alkali hazards, adjusting soil acid-base balance, and enhancing soil fertility and water retention, but crops cannot absorb organic matter and trace elements in soil well, making Conditioners do not provide immediate results
