Abstract

The invention discloses a saline land improver and a preparation method thereof. The preparation method comprises the following steps: (1) dissolving water-soluble calcium, inorganic nutrients, and a water-soluble surfactant into deionized water, mixing, and stirring to obtain a water phase (I); (2) adding an auxiliary surfactant and an oil-soluble surfactant into an organic solvent, mixing, and stirring to obtain an oil phase (II); (3) in the presence of an initiator and an inert gas atmosphere, carrying out polymerization reactions among the water phase (I), the oil phase (II), and membrane-coated monomers to obtain reversed-phase microcapsule suspension emulsion. The provided saline land improver can improve the buffering performance of soil, reduce the soil pH value, effectively reduce the sodium ion concentration in plant cells, and improve the salt resistant performance of crops.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a saline-alkali soil improver and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for various types of soil affected by the saline-alkali components in the soil, including saline soil, alkaline soil, and a variety of salinized and alkalized soils, as well as soil types that commonly coexist with desert soils and have salt crusts. Saline soil refers to the soil type after a large amount of neutral salts have accumulated to a certain concentration (the salt content is greater than 0.5%-2%, the salt composition is different, and the lower limit of the salt content is different). The main salt components are sodium chloride and sodium sulfate. Alkaline soil is that under the influence of sodium bicarbonate, sodium carbonate, etc., the soil properties deteriorate after the sodium ion reaches a certain value in the exchan...
