Abstract

The invention discloses a special-effect amino acid compound fertilizer for kudzu root growth, which is prepared from the following raw materials in percentage by weight: 10-20% of amino acid base solution, 60-70% of nitrogen fertilizer, 1-2% of zeolite powder, 2-5% of manganese sulfate, 1-2% of humic acid, 2-3% of composite biological bacterium, 1-6% of zinc sulfate, 5-15% of basic amino acid and 50-60% of phosphate fertilizer. The compound fertilizer contains abundant minor elements, can effectively improve the soil structure, eliminates soil hardening and enhances the water retention capacity of soil; the compound fertilizer effectively enhances the crop yield and improves the crop quality; and the compound fertilizer promotes the growth intumescence of the kudzu root rhizome, and enhances the puerarin content in the rhizome and the blooming rate.

Description

technical field [0001] The invention relates to a compound fertilizer containing amino acid and a preparation method thereof, belonging to the field of agricultural fertilizers. Background technique [0002] At present, most of the phosphate fertilizers used are industrially produced phosphate fertilizers. The content of free acid is too high, which has the disadvantages of being easy to be damp and easy to agglomerate. At the same time, it can only be used as base fertilizer, and the utilization rate is only 10%-20%. The utilization rate is the lowest among all chemical fertilizers. Excessive free acid content in phosphate fertilizer will fix the mineral elements in the soil. Long-term large-scale use will lead to soil acidification and compaction, and the loss of nitrogen, phosphorus and potassium in the soil, resulting in a decline in land fertility, hindering the growth of farm crops, and reducing yield and quality. At present, problems such as soil acidification, comp...
