Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a nitrogen-fixing microbial compound fertilizer and a preparation method thereof. Background technique [0002] In current agricultural production, fertilizers provide a variety of nutrients needed by plants, and play an important role in improving soil properties, improving soil fertility, increasing crop yields, and improving crop quality. [0003] At present, there are many kinds of chemical fertilizers on the market, and some fertilizers blindly pursue the high content of nitrogen, phosphorus and potassium fertilizers required by crops, or unreasonable fertilization, improper fertilization methods, resulting in low fertilizer utilization efficiency, reduced fertilizer efficiency, crop nutrient loss, and quality degradation. , Soil acid-base balance imbalance, soil compaction or water loss are serious, and have a bad impact on the ecological enviro...
