Saline-alkali soil conditioner

Abstract

The invention relates to a composition for improving soil, in particular relates to a saline-alkali soil conditioner. The saline-alkali soil conditioner is prepared by mixing the following components by weight percent: 20%-35% of sulfur powder, 20%-30% of humic acid, 5%-10% of bentonite, 20%-25% of magnesium sulfate heptahydrate, 8%-12% of calcium superphosphate, 1%-2% of zinc sulfate heptahydrate and 2%-3% of boric acid. The saline-alkali soil conditioner can be used for regulating acid-base level of the soil, and effectively supplementing microelements in the soil, improving the nutritional deficiency symptom of crops, chelating harmful heavy metal elements in the soil, reducing saline and alkali degree, promoting the soil to form a granular structure, improving root growth environment of crops, enhancing saline and alkali resistance of crops, disease resistance and cultivation of resilience, reducing the harm of saline and alkali to plant roots, and releasing the effective phosphorous solidified by the soil, increasing soil fertility, holding water and saving fertilizer so as to finally and completely improve the soil, recover the soil fertility, increase both production and income and improve crop quality and utilization rate of the fertilizer.

Description

technical field [0001] The invention relates to a soil improvement composition, in particular to a saline-alkali soil conditioner. Background technique [0002] In the existing market, the conditioning products for soil improvement have a single effect, and the method of adding organic fertilizer or bacterial fertilizer is mostly used to achieve soil improvement, which cannot fundamentally change the growth environment of crops, resulting in repeated occurrence of saline-alkali, and the effect of improving saline-alkali land is not good. Obviously, it cannot meet the needs of agricultural planting. [0003] In areas with good water source conditions, the improvement of saline-alkali land is carried out by means of matching irrigation and drainage, storage of light salt and pressing salt, and irrigation and washing of salt. However, due to the limitation of water source conditions, it cannot be realized in many areas of our country. Contents of the invention [0004] 1. Te...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to address the above-mentioned problems in the prior art, and to provide a soil conditioner for saline-alkali soil, which effectively solves the problem of the single effect of conditioning products in the existing market on improving soil, and more organic fertilizers or fungi are used. The method of using fertilizer to improve soil cannot fundamentally change the growing environment of crops, resulting in repeated occurrence of saline-alkali, and the effect of improving saline-alkali land is not obvious, and the product is not targeted and cannot meet the needs of agricultural planting.
