Abstract

The invention relates to a soil remediation type multifunctional biological fertilizer and a preparation method thereof, comprising the following steps: respectively fermenting the strain of Paenibacillus polymyxa and the strain of Bacillus pumilus to obtain a first fermentation liquid and a second fermentation liquid liquid; adsorbing the adsorption carrier with the first fermentation liquid and the second fermentation liquid, respectively, to obtain the first mixture and the second mixture respectively; mixing the first mixture and the second mixture to obtain the first mixture The three mixtures are then mixed with inorganic nutrients to obtain a soil remediation multifunctional biological fertilizer. The soil remediation multifunctional biological fertilizer is applied to the soil of soil-borne diseases and secondary salinization to cultivate crops. The soil of the present invention Restorative multifunctional biological fertilizers can reduce the application amount of conventional fertilizers, effectively improve the utilization rate of conventional fertilizers, improve the soil environment to a large extent, have better control effects on crop diseases, and greatly improve the quality of crops .

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a soil remediation type multifunctional biological fertilizer and a preparation method thereof. Background technique [0002] The problem of soil quality degradation in my country's facility vegetable fields is becoming more and more serious, such as nutrient imbalance, soil acidification, soil secondary salinization, soil-borne diseases, soil heavy metal pollution, etc. continuous development. Therefore, research on soil degradation and restoration in vegetable fields is particularly important. [0003] Soil secondary salinization in facility vegetable fields refers to the increase in soil salinity in protected areas due to unreasonable application of fertilizers, inappropriate cultivation and management measures and other human factors during the production of vegetable crops in facility vegetable fields, thereby affecting crop yields. and quality phenomena. So...
