Abstract

The invention relates to a composite microbial organic fertilizer for saline-alkali soil improvement. The composite microbial organic fertilizer for saline-alkali soil improvement comprises Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, silicate bacterium, mould fungus, fulvic acid, amino acids and bentonite. The preparation method comprises the following steps: screening, preparing a composite microbial inoculant, concentrating the fermentation liquid, drying, and carrying out high-temperature composting rotting fermentation. When the composite microbial organic fertilizer is used for improving the saline-alkali soil, the crop yield is increased by 19-40%, the soil pH is lowered by 0.2-0.8, the electric conductivity (EC) is lowered by 0.5-0.8, the available phosphorus content is increased by 2.0-4.4 mg / kg, the quick-acting potassium content is increased by 40-68 mg / kg, and the quantity and diversity of soil microbes are obviously increased.

Description

technical field [0001] The invention relates to a compound microbial organic fertilizer, in particular to a compound microbial organic fertilizer for improving saline-alkali land. Background technique [0002] Saline-alkali soil is the main reserve resource of arable land in my country, and the development and utilization of saline-alkali soil resources has always been one of the major issues in my country's agricultural production. Large-scale improvement and utilization of saline-alkali land, increasing the area of ​​cultivated land, restoring the degraded ecological environment, and continuously improving the comprehensive agricultural production capacity are of great strategic significance for ensuring my country's food security. [0003] For a long time, there have been many methods for improving saline-alkali land, and there are also techniques for improving saline-alkali land using biology, but the effect is limited. How to improve the technical level of using biotech...
