Abstract

The invention relates to the technical field of soil remediation, in particular to a saline alkali soil remediation agent and a remediation method. The soil remediation agent comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 60-90 parts of desulfurized gypsum, 5-20 parts of sawdust, 2-10 parts of zeolite, 5-10 parts of honeycomb briquette ash, 50-100 parts of citric acid residues, 5-10 parts of river sand, 80-100 parts of diatomite, 5-20 parts of seaweed residues, 10-30 parts of charcoal, 60-80 parts of shrimp shells and 1-5 parts of polyaluminum ferric silicate. The component B is prepared from the following components in parts by weight: 10-50 parts of humic acid powder, 10-14 parts of trace element fertilizer and 2-10 parts of microorganism mixed bacteria liquid. According to the saline alkali soil remediation method, the saline alkali soil remediation agent is added into saline alkali soil for remediation, theremediation method is simple, comprehensive remediation of the saline alkali soil can be guaranteed, and the soil activity is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a saline-alkali soil remediation agent and a remediation method. Background technique [0002] Saline-alkali land is an important class of land resources, which can be found in arid and semi-arid regions on all continents of the world. As of 2000, the total area of ​​saline-alkali soil in the world is about 1×10 9 hm 2 . In our country there are 0.99×10 8 hm 2 The saline-alkali land is mainly distributed in Inner Mongolia and the western part of Northeast China, Yinchuan Plain, Xinjiang, Shanxi Basin, North China Plain, and Tibet. Due to high salt content, high pH value and sodium adsorption ratio, poor air permeability, easy compaction, and low fertility, saline-alkali soil inhibits crop growth and affects the sustainable development of agriculture and the expansion of newly-added cultivated land. Therefore, the remediation of saline-alkali soil has always been a ...
