Abstract

The invention discloses a multifunction soil conditioner and a preparation method thereof. The multifunction soil conditioner takes leonardite as a main raw material, and is produced by a biochemical extraction process of about 120 days. The soil conditioner provided in the invention can effectively improve the soil environment, help aerobiont growth, shield salt in high-alkali or high-sodium soil, improve the effectiveness of plant nutrition, and stimulate root growth and depth extension. The soil conditioner disclosed in the invention can improve saline-alkali soil, improve soil breathability and water retention, stimulate formation of organic matters, and increase the number of beneficial microorganisms in the soil. In addition, the soil conditioner has the advantages of low dosage and convenient use, thereby greatly saving labor force and reducing cost.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a multifunctional soil conditioner and a preparation method thereof. Background technique [0002] With the continuous deepening of my country's reform and opening up, the pace of the country's urbanization process has accelerated, and the effective agricultural land area has a tendency to gradually decrease. Due to the increase in population, the demand for agricultural products is also increasing, and the contradiction between food supply and demand is becoming increasingly prominent. In order to obtain higher yields in agricultural production, in addition to implementing measures such as adjusting the planting structure and increasing the multi-cropping index of cultivated land, a large number of chemical fertilizers and pesticides have been used in cultivation, resulting in varying degrees of acidification, salinization, and structural changes in the cultivat...
