Abstract

The invention discloses an amino acid micro-fertilizer which comprises the following raw materials by weight percent: 4-6% of humic acid, 5-7% of phosphorus pentoxide, 8-12% of potassium oxide, 0.05-2.00% of sulfur element, 0.03-0.50% of boron element, 0.01-0.50% of zinc element, 0.01-0.20% of iron element, 0.03-0.50% of molybdenum element and 0.05-1.00% of magnesium element; and the amino acid content is that 35-45% of amino acid hydrolysate is complemented to 100%. According to the amino acid micro-fertilizer, waste cornifin is used as the raw material, an amino acid solution is prepared through strong acid hydrolysis; and through concentration and chelation with macroelements, secondary elements and microelements, and the obtained amino acid micro-fertilizer is free of biologic hormone, high in effectiveness of nutrient availability and comprehensive in nutrition. The amino acid micro-fertilizer is applied to crop iron-deficiency prevention in a spraying, sprinkling irrigation or broadcasting mode, has the advantages of good solubility, no sediment, no pollutant, is easy to be absorbed by crops, flexible in application mode, and remarkable in prevention and treatment effect, can prompt the absorption of crops to amino acid, phosphorus, potassium and microelements, improves the yield and quality of crops, and modifies the soil structure.

Description

technical field [0001] The invention relates to the technical field of amino acid micro-fertilizer, in particular to an amino acid micro-fertilizer for preventing and treating iron deficiency in crops and a preparation method thereof. Background technique [0002] Iron is an essential micronutrient element for plants and plays an indispensable role in plants. In recent years, due to the large-scale planting of high-yield crops, the lack of input of organic fertilizers and micro-fertilizers has caused soil nutrient imbalance, especially the development of land monoculture, the accumulation of crop root exudates, and serious leaching of soluble nutrients, resulting in iron deficiency in crops The occurrence of the disease is becoming more and more serious, which not only affects the normal growth and development of crops, but also has a greater impact on the yield and quality of crops, and can lead to the death of the entire crop in severe cases. Sugarcane, vegetables, melons...
