Soil conditioner capable of improving microdomain environment around saline-alkali soil cultivated land crop root system

Abstract

The invention relates to the fields of soil, organic and inorganic chemistry and the like, in particular to a soil conditioner capable of improving a microdomain environment around a saline-alkali soil cultivated land crop root system, which can reduce the salt content of rhizosphere soil, reduce the alkalization degree, improve a nutritional environment and promote the growth and development of crops. The fertilizer comprises the following components in percentage by weight: 15%-35% of aluminum sulfate, 30%-55% of phosphogypsum, 1%-5% of polyacrylamide, 10%-30% of lignite humic acid, 1%-4% of monopotassium phosphate, 1%-3% of polyglutamic acid and 0.1%-0.2% of rooting powder. By reducing the salt content and pH value of the soil around the root systems of crops in the saline-alkali farmland, increasing the organic matter content of the soil, improving the physicochemical properties such as the soil structure and the soil nutrient environment, increasing the utilization rate of nutrients such as nitrogen and phosphorus and enhancing nutrition, the soil conditioner enhances stress resistance and promotes growth and development by means of the monopotassium phosphate which is a plant growth regulator; rooting powder is used for promoting rooting, polyglutamic acid is used for promoting root system growth and development, crop nutrient absorption is promoted, crop growth and development are promoted, and the purpose of increasing yield and income is achieved.

Description

technical field [0001] The present invention relates to the fields of soil, organic and inorganic chemistry, etc., and specifically relates to a method for reducing the salinity of rhizosphere soil, reducing the degree of alkalization, improving the nutritional environment, and promoting the growth and development of crops, which has the ability to improve the micro-domain environment around the roots of cultivated crops in saline-alkali soil (roots) International) soil amendments. Background technique [0002] Saline-alkali land is an important reserve cultivated land in my country. Due to the influence of saline-alkali and other obstacles, the yield per unit area of ​​crops is not high, and the potential for increasing production is huge. The measures to improve saline-alkali land mainly include engineering, biological and chemical measures. Engineering measures are saline-alkali land control measures within the region and watershed range. After the implementation of sali...

Problems solved by technology

Because no polyacrylamide is added, the soil structure has not been improved as it should be, and the leaching effect is poor, and the effect is not good; because no rooting powder is added, the root growth is not good, and the crop yield is not high; Growth-promoting substances, root development is poor; due to the lack of addition of potassium dihydrogen phosphate, a phosphorus and potassium fertilizer, and crop growth regulator, crop growth is poor
