Soil conditioner with multiple benefits

Abstract

The invention relates to a soil conditioner with multiple benefits. The soil conditioner with multiple benefits is prepared by adopting the steps: screening 2-5 parts of biochar, 1-5 parts of polyacrylamide, 1-4 parts of potassium humate, 1-4 parts of ammonium lauryl sulfate polymer and 1-3 parts of bentonite by using a 100-mesh sieve after crushing, charging in a stirrer, pelleting by using a fertilizer pelleting machine after fully uniformly mixing, and processing into a final uniform smooth particle finished product by adopting a multistage granulated fertilizer spheroidizing machine to obtain the soil conditioner with multiple benefits. According to the soil conditioner, a soil sand claying ratio can be adjusted, the soil structure is improved, and the formulation of a granular structure is promoted; the soil water retention and holding capacity is improved, the available water supply is increased, the soil pH value is adjusted, and the aluminum toxicity damage is reduced or decreased; the saline-alkali soil is improved, the soil base saturation percentage and the cation exchange capacity are adjusted; an unbalanced soil nutrient system is conditioned, the available nutrient supply is promoted; the polluted soil is remediated, the heavy metal ion inactivation function is achieved; a soil microflora is adjusted, and the soil microorganism environment is kept good.

Description

technical field [0001] The present invention relates to a soil conditioner with multiple benefits. Background technique [0002] Soil is the foundation of agricultural planting, and a healthy soil environment is the foundation of agricultural development. In recent years, irrational tillage, over-planting, massive input of agrochemicals, and aging of ditch facilities widely exist in major agricultural areas in my country, which have led to the general thinning of the farmland soil and the serious imbalance of nutrients, resulting in soil compaction. Soil biological properties are degraded, soil acidification, gleization, and salinization are increasing, drought and waterlogging capabilities are poor, and the basic soil fertility of cultivated land continues to decline. [0003] The deterioration of soil conditions has brought many negative effects on agricultural production. For example, soil water and fertilizer retention performance is poor, drought resistance and disaste...

Problems solved by technology

At the same time, soil degradation problems such as soil acidification in the south, shallowing of the cultivated layer in North China, and salinization of cultivated land in the Northwest have become increasingly prominent. The decline in the quality of cultivated land has posed a certain threat to the stable production of grain, and it has also sounded the alarm for national food security.
