Preparation method of compound amino acid cheated nano-selenium leaf fertilizer

Abstract

The invention relates to a preparation method of a compound amino acid cheated nano-selenium leaf fertilizer. The preparation method comprises the following steps: (1) performing enzymatic hydrolysis on blood cell protein powder by using compound enzyme; (2) adding 3wt%-5wt% of sugar alcohol into enzymatic hydrolysis liquid, and reacting at 50-70 DEG C for 1-2 hours to obtain reaction liquid; (3) adding nano-selenium, and reacting at 45-65 DEG C for 1-2 hours to obtain initial liquid; (4) adding 5wt%-6wt% of nano titanium dioxide into the initial liquid, reacting at 45-55 DEG C for 0.5-1 hours, heating to 90-95 DEG C, and keeping the temperature for 10-20 minutes to form a final product. The leaf fertilizer prepared by adopting the method is rich in high-activity oligopeptide and free amino acid, easy to absorb by crops and quick to transport in the crops, and selenium and sugar alcohol can be quickly and completely dissolved; the problem of difficult absorption of the leaf fertilizer is solved, the growth speed of the crops is greatly increased, the disease resistance of the crops is greatly improved, and the quality of the crops is improved.

Description

technical field [0001] The invention relates to the field of preparation of foliage fertilizer, in particular to a preparation method of compound amino acid chelated nano-selenium foliage fertilizer. Background technique [0002] Foliar fertilizers are often used in agriculture to quickly supplement the nutrients needed by plants. Because of their convenience, quickness, better absorption effect and less waste than root fertilization, various nutritional or functional foliar fertilizers have gradually entered the market in recent years. However, in recent years, most of the foliar fertilizers produced in China have low effective content and single function, and most of them are to supplement trace elements for crops, and have single nutritional components. The Chinese patent with the patent number CN101891520 disclosed a kind of amino acid foliar fertilizer on August 29, 2012, which is made from the following materials in terms of mass percentage: 30%-50% plant amino acids, ...

Problems solved by technology

However, in recent years, most of the foliar fertilizers produced in China have low effective content and single function. Most of them are to supplement trace elements for crops and have single nutritional components.

The Chinese patent with the patent number CN101891520 disclosed a kind of amino acid foliar fertilizer on August 29, 2012, which is made from the following materials in terms of mass percentage: 30%-50% plant amino acids, 1%-5% compound nitrophenol Sodium, 15% -25% urea, 5% -10% ferrous sulfate, 5% -10% borax, 3% -5% copper sulfate, 0.5% -1% ammonium molybdate, 1% -2% manganese sulfate, 4% -8% zinc sulfate, 10% -20% organic silicon and the balance of water, the foliar fertilizer stimulates the activity of enzymes in crops, improves the photosynthetic efficiency of crops, accelerates the absorption and operation of internal nutrients, and increases the content of chlorophyll , increase the accumulation of stem matter and sugar content, improve crop quality, enhance crop resistance to drought, disease resistance, stress resistance and immunity, etc., all have obvious effects, but there are also deficiencies, for example, a single mixture of multiple elements to make a concentrated solution , mixed with water, the element utilization rate is not high, the effect is not stable enough; after absorption, the transportation efficiency in the crop is low, etc.
