Abstract

The invention provides a preparation method of a soil alkaline conditioner. The conditioner product is prepared from mixing different amounts of citric acid, lime, EDTA, fulvic acid, salicylic acid, tween, AESA and water step by step, stirring and synthesizing. By complexing salt ions and then eluviating to the deep layer of the soil, the conditioner has the advantage of fewer doses, but has multiple effects of improving the soil, promoting the eluviation of salt, improving the salinity tolerance of crops and the like.

Description

technical field [0001] The invention relates to a preparation method of a soil saline-alkali conditioner. Background technique [0002] In the prior art, soil saline-alkali improver is an effective method for improving saline-alkali land, but many improvers are only aimed at soil, and the amount of application is large, so most of them use industrial and agricultural waste, even so the total cost per unit area is high , but it has no obvious effect on improving the salt tolerance of crops. Contents of the invention [0003] The purpose of the present invention is to overcome the above deficiencies and provide a preparation method of soil saline-alkali conditioner. The conditioner is complexed by salt ions and then leached into the deep layer of the soil. The dosage is small, but it can improve soil and promote salt leaching. And improve the salt tolerance of crops and other multiple functions. [0004] The object of the present invention is achieved by the following meas...
