Problems solved by technology

In addition, the use of a single regulator in crops also has obvious defects. One is that it cannot prevent and control plant physiological diseases.
The second is that chlormequat, chlorbutazone, diconazole, etc., which are popularized as chemical control, are used in small amounts and have no obvious effect; when used in large amounts, the leaves become smaller, lodging resistance does not increase production, and the cost is high. It is difficult to treat both symptoms and root causes, and it takes a lot of work.

preparation example Construction

[0041] The present invention also provides the preparation method of the water-soluble fertilizer described in the above technical scheme, comprising the following steps:

[0042] (1) mixing amino acid with water to obtain amino acid mixed solution;

[0043] (2) Mix the amino acid mixture with citric acid and medium and trace element compounds, and perform a chelation reaction at 60-80° C. for 1-2 hours;

[0044] (3) Mix the chelation reaction solution obtained in step (2) with salicylic acid and chitosan oligosaccharide, and continue the chelation reaction for 0.2 to 0.5 hours;

[0045] (4) Mix the chelating reaction solution obtained in step (3) with the surfactant, adjust the pH value of the solution to neutral acidity, and obtain a water-soluble fertilizer suitable for the integration of water and fertilizer for cotton.

[0046] In the present invention, first, a mixed solution of amino acids is prepared. Amino acid and water are mixed in proportion to prepare amino acid...

Abstract

The invention discloses water-soluble fertilizer suitable for cotton water-fertilizer integration and a preparation method of the water-soluble fertilizer. The water-soluble fertilizer is prepared from biostimulant substances and medium trace elements. The biostimulant substances comprise amino acid, salicylic acid, citric acid and oligochitosan; the medium trace elements comprise zinc, manganese,boron, iron, copper, zinc and magnesium. According to the preparation method disclosed by the invention, the biostimulant substances with various biological activities are combined with the medium trace elements by adopting an amino acid chelating technology, so that synergistic absorptivity of all the substances is greatly enhanced, disease resistance and stress resistance are effectively achieved, the growth effect of cotton is promoted and the cotton yield is greatly improved.

Description

technical field [0001] The invention relates to the fields of agricultural biotechnology and fertilizers, in particular to a functional water-soluble fertilizer with disease resistance and stress resistance for promoting cotton growth and a preparation method thereof. Background technique [0002] As one of the main economic crops, cotton has a wide planting area in my country. Cotton production is closely related to people's daily life. Improving cotton quality and increasing cotton production are of great significance to the development of our light textile industry and the improvement of people's living standards. The quality and quality of cotton are not only related to the natural conditions of soil, water and light, but also have a lot to do with the management of cotton fertilization. [0003] In recent years, great changes have taken place in the structure of fertilizers. Organic fertilizers with full nutrients have decreased year by year, and the amount of nitrogen,...
