Problems solved by technology

[0005] At present, macroelement water-soluble fertilizers and inducers have been partially applied in the planting of economic crops, but macroelement water-soluble fertilizers and inducers are used separately as fertilizers and pesticides, and a small number of bio-inducers that can activate plant resistance are used as organic fertilizers. fertilizer, but its use is large, the effect is unstable, and its water solubility is poor, so it is not suitable for application in water-soluble fertilizers
At the same time, the chemical inducers are mainly fat-soluble, and the water-soluble inducers are relatively few, which also restricts the application of water-soluble fertilizers with a large number of elements.

Abstract

The invention discloses a macroelement water-soluble fertilizer capable of enhancing the disease resistance of plants and a preparation method and application thereof. The water-soluble fertilizer is prepared by evenly mixing, by mass, 4%-6% of beta-aminobutyric acid, 14.5%-24.7% of potassium nitrate, 1.0%-11.9% of monoammonium phosphate, 23.6%-38.0% of monopotassium phosphate, 31.2%-38.0% of urea, 0.4%-1.0% of boric acid and 0.2%-3.9% of microelements, wherein the microelements include one or a mixture of EDTA-Fe, EDTA-Zn, EDTA-Mn, EDTA-Cu and sodium molybdate. According to the macroelement water-soluble fertilizer and the preparation method and application thereof, water, fertilizer and pesticide integration can be achieved, the disease resistance and stress resistance of plants can be improved while balanced nutrients are efficiently supplemented to plants, pesticide damage and pesticide residues can be avoided, time and labor are saved, and operation is convenient.

Description

Technical field [0001] The invention belongs to the technical field of macroelement water-soluble fertilizer. Background technique [0002] Water-soluble fertilizer is a liquid or solid fertilizer that is dissolved or diluted by water and used for irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds and dipping roots and other purposes. Compared with traditional superphosphate, granulated compound fertilizer and other varieties, water-soluble fertilizer has obvious advantages. It can be completely dissolved in water and can be directly absorbed and utilized by the roots and leaves of crops. Its effective absorption rate is higher than ordinary Chemical fertilizer is more than doubled, reaching 80%-90%, and the fertilizer effect is fast, which can solve the nutritional needs of high-yield crops during the rapid growth period. With the drip irrigation system, the water requirement is only 30% of the ordinary fertilizer, and the fertilization oper...
