Problems solved by technology

Although the use of microbial amendments to improve saline-alkali soil is still in the experimental stage, most of the amendments have poor improvement effects, and the application cycle is long, generally taking 2 to 3 years. However, for farmers, this method is more practical. Further research is required

Abstract

The invention discloses a microbial saline-alkali soil conditioner as well as a preparation method and application thereof, and belongs to the technical field of soil improvement. The improver comprises a carrier and compound microorganisms, the carrier comprises the following components in percentage by mass: 10-15% of attapulgite powder, 8-12% of humic acid and the balance of organic fertilizer, and the compound microorganisms comprise bacillus subtilis, actinomycetes and paenibacillus mucilaginosus. Compared with the prior art, the conditioner has the advantages that the conditioner is applied to saline alkali soil to be improved, the application amount is 150 kg/mu, the conditioner is applied to a crop growth cycle, the soil pH can be effectively reduced by 0.1-0.5 unit, and the soil bulk density is reduced by 10%.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a microbial saline-alkali soil improver and its preparation method and application. Background technique [0002] Saline-alkali land includes: primary salinization, secondary salinization and various alkalization soils. Saline-alkali land is a "pure land" that has not been polluted by chemical fertilizers and pesticides, and has low heavy metal content. Therefore, defining saline-alkali land as a reserve arable land resource, that is, a strategic reserve resource of arable land, is of great significance for ensuring national food security and ecological security. Under the actual conditions of lack of reserve cultivated land resources, it is very important to carry out the process of directional cultivation, conservation and tending from saline-alkali land (reserve cultivated land) to cultivated land. [0003] Regarding the improvement of saline-alkali soil, the overall...
