Abstract

The invention belongs to the technical field of saline-alkali soil improvement fertilizers, particularly relates to a solid-liquid synergistic saline-alkali soil conditioner, and further discloses a preparation method for the solid-liquid synergistic saline-alkali soil conditioner. According to the solid-liquid synergistic saline-alkali soil conditioner, according to the actual conditions of soil,effective measures are taken according to local conditions, carbon manure decomposed materials, humic acid and acidic residues serve as solid components, and wood vinegar serves as a liquid component. The prepared saline-alkali soil conditioner has the advantages that under different periods and soil conditions, the solid components and the liquid components are used, so that the physicochemicalenvironment of the soil can be effectively improved, the growth of plants can be promoted, and the growth and development of fruits can be promoted.

Description

technical field [0001] The invention belongs to the technical field of fertilizer for saline-alkali soil improvement, in particular to a solid-liquid synergistic saline-alkali soil improver, and further discloses a preparation method thereof. Background technique [0002] The so-called saline-alkali soil mostly refers to arid or semi-arid low-lying areas. Under the conditions of strong evaporation and high groundwater level, the soluble salt rises with the soil capillary, and the soil, especially the soil surface, accumulates a kind of soil formed by excessive salt. Types of. Due to the accumulation of salt in saline-alkali land, the salt contained in the soil affects the normal growth of crops. Among them, soil salinization or soil salinization formed due to the influence of natural conditions such as climate, topography, and soil structure is called primary soil salinization or primary salinization; Land development behavior and development activities lead to salinizatio...
