Problems solved by technology

Predecessors have done a lot of research work on the improvement of salinization. Among them, the improvement of salinization by water conservancy engineering measures is better, but the problem is that the fresh water resources in the Hexi Corridor are scarce and it is difficult to promote it on a large scale; the improvement of halophytes is a development direction, but the cultivation of halophytes is difficult and takes a long time
Chemical measures to improve salinization are an important measure, but only focus on the improvement effect of a single improver on salinization

Abstract

The invention relates to a saline soil modifying agent. The modifying agent is prepared as follows: mixing a trophic factor, a water-retaining agent, aluminum sulfate, sulphur and polyvinyl alcohol according the weight ratio of (0.45-0.60):(0.002-0.02):(0.11-0.14):(0.28-0.36):(0.008-0.05) to obtain a mixture, and adding a bio-organic fertilizer into the mixture and mixing, wherein the weight ratio of the mixture to the bio-organic fertilizer is 1:(33-35). According to the saline soil modifying agent, the cyclic utilization of resources is promoted, the value is increased, saline ions are leached, the physicochemical properties of saline soil are effectively improved, a granular structure is formed, the power of hydrogen of saline soil is reduced, and the technical support is provided for the development and the utilization of saline soil resources.

Description

technical field [0001] The invention relates to the field of agricultural soil, in particular to a saline soil improver. Background technique [0002] my country's saline-alkali land is mainly distributed in the North China Plain, Northeast Plain, Northwest inland areas and coastal areas. China currently has 33.82 million hectares of salinized land, and the salt content is composed of Na + , Ca 2+ , Mg 2+ These 3 cations and Cl - , SO 4 2-　 , HCO 3 - , CO 3 2- These 4 anions make up NaCl, CaCl 2 , MgCl 2 , Na 2 SO 4 , CaSO 4 , MgSO 4 , NaHCO 3 , Ca (HCO 3 ) 2 , Mg(HCO 3 ) 2 , Na 2 CO 3 , CaCO 3 , MgCO 3 A total of 12 kinds of salts, the toxic effects of various salts on plants are as follows: Na 2 CO 3 >NaHCO 3 >NaCl>CaCl 2 >MgSO 4 >Na 2 SO 4 . Predecessors have done a lot of research work on the improvement of salinization. Among them, the improvement of salinization by water conservancy engineering measures is better, ...
