Soil conditioner, preparation method thereof and method for conditioning salinized soil on afforestation lands

Abstract

The invention relates to the technical field of salinized soil conditioners and in particular relates to a soil conditioner, a preparation method thereof and a method for conditioning salinized soil on afforestation lands. The soil conditioner is obtained by the following preparation method: uniformly mixing a required amount of desulphurization gypsum, humic acid, magnesium sulfate, water-soluble polymers and solid acid. By adopting the soil conditioner and an application method of the soil conditioner, the pH value, alkalinity and total salt content of the salinized soil can be reduced, the conditioning cost of the salinized soil is reduced and the conditioning effects of the salinized soil are effectively improved, thus improving the soil texture and fertility and then increasing the seedling survival rate. The soil conditioner and the method have the function of accelerating agricultural development and ecological shelter forest construction of salinized regions.

AI Technical Summary

Benefits of technology

This patented technology helps prevent or decrease acidification caused by salt water used for growing crops during rainwater irrigation systems that use sea water instead of freshly mined seawater (salt). By reducing these factors, this new system reduces harmful impact on plants' roots while still maintaining good quality vegetations at their best level.

Problems solved by technology

This patented technical solution involves improving the quality and quantity of salty ground by reducing its alkality with respectable levels of mineral elements like calcium chloride, magnesia, silica, silt lime clay, ammoniacal phosphorus, nitrogen, iron oxides, manganese, chromite, copper, zinc, etc., while also addressing issues related to soil salification caused by low pH values and strong negative ion content.
