Special-effect amino acid compound fertilizer for pomegranate growth and preparation method thereof

Abstract

The invention discloses a special-effect amino acid compound fertilizer for pomegranate growth. The fertilizer is prepared from the following raw materials in percentage by weight: 10-20% of amino acids, 60-70% of a nitrogen fertilizer, 1-2% of zeolite powder, 2-5% of manganese sulfate, 1-2% of a water-retaining agent, 1-2% of humic acid, 1-2% of bentonite, 2-3% of compound biological bacteria, 1-6% of zinc sulfate, 5-15% of basic amino acids and 5-8% of a binding agent. The fertilizer disclosed by the invention has the beneficial effects that 1, the fertilizer contains abundant trace elements which can be used for effectively improving the soil structure, eliminating the soil hardening and enhancing the water retaining capacity of soil; 2, the fertilizer can be used for effectively increasing the yield of crops and improving the quality of the crops; and 3, the fertilizer can be used for overcoming the defect that a phosphatic fertilizer is corrosive, high in moisture absorption, easy to agglomerate and poor in scattering property and aggravates soil acidification.

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...
