Abstract

The invention relates to a soil remediation type multifunctional biological fertilizer and a preparation method thereof. The preparation method comprises the following steps: fermenting a paenibacillus polymyxa strain and a bacillus pumilus strain separately to obtain a first fermentation liquor and a second fermentation liquor; respectively adsorbing the first fermentation liquor and the second fermentation liquor with an adsorption carrier to correspondingly obtain a first mixture and a second mixture; and mixing the first mixture with the second mixture to obtain a third mixture, then, mixing with inorganic nutrients to obtain the soil remediation type multifunctional biological fertilizer. The soil remediation type multifunctional biological fertilizer is applied to soil with soil-borne diseases and secondary salinization to cultivate crops. According to the soil remediation type multifunctional biological fertilizer, the application amount of conventional fertilizers can be reduced, the utilization rate of the conventional fertilizers is effectively increased, the soil environment can be improved to a great extent, the prevention and treatment effect on crop diseases is good,and the quality of crops is improved to a great extent.

Description

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