Soil conditioner for adjusting soil acidity or alkalinity and alleviating soil salinization and preparation method thereof

Abstract

The invention provides a soil conditioner for adjusting soil acidity or alkalinity and alleviating soil salinization and a preparation method thereof. The soil conditioner comprises the following ingredients (by weight): 25-65 parts of fermented spent mushroom compost, 15-45 parts of grass and wood charcoal, 5-25 parts of oyster shell powder, 3-15 parts of potassium fulvic acid, 2-10 parts of algaextract, and 1.5-11 parts of Bacillus spp. By synergism of spent mushroom compost, oyster shell powder, potassium fulvic acid and alga extract and through microbial regulation effect of the added microbial inoculant, soil structure can be remarkably improved, gas permeability of soil is enhanced, soil micro-environment is restored, quantity and types of useful bacterial colonies in soil are increased, soil acidity or alkalinity is regulated, soil salinization is alleviated, and activity of heavy metals is inactivated. Cyclic utilization of wastes such as spent mushroom compost, grass and woodcharcoal and the like is realized, and production cost is low. The invention is beneficial to large-scale industrial production and large-scale promotion and application.

Description

technical field [0001] The invention belongs to the technical field of soil conditioning and restoration, and in particular relates to a soil conditioner for regulating soil pH and alleviating soil salinization and a preparation method thereof. Background technique [0002] Soil is the foundation of human existence. The composition of soil is solid phase, liquid phase, and gas phase three types of substances, mainly including minerals, organic matter, water, air and microorganisms. Healthy soil should include about 45% of minerals, about 25% of air, about 25% of water, about 5% of organic matter and about 1% of microorganisms. However, due to the long-term state of high intensification, high multiple cropping index, and high input of fertilizers, crop cultivation on the soil has caused a series of soil obstacles such as crop yield decline, soil secondary salinization, soil acidification, and nutrient imbalance. as follows: [0003] 1. The diversity of soil microorganisms ...

AI Technical Summary

Problems solved by technology

Causes frequent occurrence of soil-borne diseases, resulting in a decrease in investment income, and with the extension of the planting period, the composition and stability of the microbial community structure and stability deteriorate year by year

[0005] 2. Soil acidification is serious

Soil acidification will also intensify the leaching of base ions such as soil nutrients K, Ca, Mg, etc., and the fixation of phosphorus will also intensify the release of toxic elements such as aluminum and manganese in the soil

In addition, soil acidification not only directly harms crops due to low pH value, but also causes damage to plants by aluminum, manganese, and hydrogen and the lack of nutrient elements P, Mo, Ca, Mg, and Fe in the soil, thereby reducing crop yields

[0007] 3. The degree of soil salinization is aggravated

When the salt content is too much, it will affect the absorption of nutrients by the crops, which will cause poor growth, decreased disease resistance, and aggravated pests and diseases, which will seriously affect the yield and quality of crops.
