Bamboo charcoal soil conditioner and preparation method thereof

Abstract

The invention discloses a bamboo charcoal soil conditioner which is prepared from the following raw materials in parts by weight: 2-4 parts of bamboo charcoal powder, 1-2 parts of bamboo liquid, 4-6 parts of humic acid, 2-3 parts of urea, 5-10 parts of biological straw, 5-10 parts of sawdust, 2-4 parts of organic fertilizer, 4-6 parts of mixed mineral powder and 10-20 parts of water-retaining agent, the biological straw is a mixture of corn straw, soybean straw and wheat straw, and the mixing ratio is 1.5: 1: 2; the mixed mineral powder is a mixture of ground phosphate rock and potassium mineral powder according to a mixing ratio of 3: 2. The bamboo charcoal soil conditioner prepared from bamboo charcoal, bamboo liquid, humic acid, urea, biological straw, sawdust, organic fertilizer, mixed mineral powder and the water-retaining agent is used twice every year and can effectively adsorb heavy metals in soil, passivate the activity of the heavy metals, improve the granular structure of the soil, loosen the soil and promote the growth of microorganisms in the soil, pesticide residues and harmful substances in soil are degraded, so that the soil ecological environment is adsorbed, and the soil quality is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a bamboo charcoal soil improver, and simultaneously the invention also relates to a preparation method of the bamboo charcoal soil improver. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic substances, water, air, microorganisms, etc., and can grow plants. Composed of organic matter produced by body decomposition, soil organisms (solid phase matter), water (liquid phase matter), air (gas phase matter), oxidized humus, etc., solid matter including soil minerals, organic matter and microorganisms are sterilized by light inhibition After the nutrients, etc., the liquid substance mainly refers to soil moisture. Gas is the air that exists in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are interrelated and re...

AI Technical Summary

Problems solved by technology

[0003] Soil is the foundation of plant growth. Excessive use of soil will reduce the content of nutrients in the soil. Pollutants such as waste gas and wastewater discharged from industrial production will increase the content of heavy metals in the soil. Sprayed pesticides will remain in the soil, which will damage the Soil is seriously polluted
