Abstract

The invention relates to a soil conditioner for adjusting soil physical and chemical properties, and a preparation method of the soil conditioner, belongs to the field of soil science, and solves the technical problem in improvement of soil structures. The active ingredients of the soil conditioner comprise the following components in parts by weight: 0.1-3 parts of N-fatty acyl amino acid salt and 0.05-1 part of a nonionic surfactant. The soil conditioner provided by the invention can improve the soil structures, reduces the soil volume weight, increases soil porosity, loosens the soil, improves the absorption of crops to nutrients, improves the utilization ratio of fertilizers, promotes crop growth, and improves crop yield; the production technology is simple, the raw materials are easy to obtain, the operation is simple, and the soil conditioner is lower in cost, safe, nontoxic, free of secondary pollution and environmental-friendly.

Description

technical field [0001] The invention relates to a soil conditioner for adjusting soil physical and chemical properties and a preparation method thereof, belonging to the field of soil science. Background technique [0002] Plants cannot grow and develop without soil. Generally, a plant fixes its root system in the soil, and can absorb water and nutrients in the soil through the root system to ensure the normal physiological activities of the plant. Soil supports plants and supplies water, fertilizer, air, and heat requirements for plant growth and development, so the physical and chemical properties and fertility of soil are of great significance to plant growth and development. [0003] At present, in the process of agricultural planting, the application of chemical pesticides and fertilizers is one of the main means to kill insects and weeds and improve soil nutrient content. Problems such as hardening and poor water and fertilizer retention capacity have caused serious ...
