Soil conditioner for improving organic carbon of soil and production method of soil conditioner

Abstract

The invention discloses a soil conditioner for improving the organic carbon of soil and a production method of the soil conditioner and belongs to the technical field of soil conditioner preparation and utilization. The soil conditioner is composed of, by mass, 22-35% of humic acid, 5-12% of cow dung, 4-12% of tobacco powder, 8-20% of grass coal, 1-6% of calcium superphosphate, 1-5% of urea, 2-6% of potassium sulphate, 9-19% of calcium magnesium phosphate fertilizer, 0.5-2.5% of manganese sulfate, 0.5-2.5% of ferrous sulfate, 1-4% of zinc sulfate, 0.5-2.5% of ammonium molybdate, 3-7% of boric acid, 1-3% of BFA fungicide and 2-5% of bentonite, and the sum of all the components is 100%. According to the soil conditioner for improving the organic carbon of the soil, the organic nutrient of humic acid is taken as the main part, the soil conditioner contains rich organic matter, the content of the organic matter in the soil can be effectively increased, a soil organic carbon pool can be improved, soil nutrients are kept balanced, the microenvironment of the soil is improved, crop root growth is stimulated, and the crop quality and yield are improved.

Description

technical field [0001] The invention belongs to the technical field of soil conditioner and its preparation and application, and in particular relates to a humic acid type soil conditioner capable of increasing soil organic carbon pool and a production method thereof. Background technique [0002] Soil organic carbon pool (SOC) is the main content of soil biochemical carbon cycle research, and its composition includes the remains of plants, animals and microorganisms, excreta, secretions and their partial decomposition products and soil humus. On the one hand, soil organic carbon is an important part of soil organic matter, an important indicator to measure soil fertility, and a major factor affecting the stability of soil structure and soil productivity; on the other hand, soil organic carbon is an important component of the biosphere and atmospheric carbon cycle In part, soil organic carbon is the source and sink of the soil as the atmosphere, affecting the CO in the atmos...

Problems solved by technology

However, in agricultural production, the main purpose is only to harvest the economic organs of plants, and the harvest index is constantly increasing, and the amount of carbon returned to the soil is very small. In addition, the continuous cultivation of the soil destroys a large amount of stable organic carbon. It causes a large loss of soil organic carbon, which seriously affects the fertility and productivity of the soil. Therefore, supplementing soil organic carbon, fertilizing the soil, and establishing a soil organic carbon pool have become the prerequisites for increasing agricultural economic income.

[0004] In agricultural production, the application of chemical fertilizers, organic fertilizers and other new fertilizers is often used to increase soil organic carbon and try to build soil organic carbon pools. However, long-term application of chemical fertilizers will destroy the soil aggregate structure, resulting in soil compaction, soil acidification, and reducing the number of soil microorganisms. Sustainable use of soil; although organic fertilizers can effectively improve the physical and chemical properties of soil, they cannot meet the nutrient elements needed for plant growth in time

Therefore, it is difficult to establish a stable soil organic carbon pool
