Abstract

The invention relates to foliar fertilizer for improving wheat powdery mildew resistance and a preparation method thereof. The foliar fertilizer is prepared from sodium bicarbonate, dipotassium hydrogenphosphate, potassium silicate, riboflavin, sucrose, fulvic acid, chitin, phytosterol, trace elements, a chelating agent, a wetting agent, a dispersant and water. The preparation method comprises adding water into a reactor, heating the water to 50-80 DEG C, adding trace elements and a chelating agent into the water, stirring the mixture for a reaction to obtain a solution A, cooling the solution to 40-50 DEG C, adding sodium bicarbonate, dipotassium hydrogenphosphate, potassium silicate, fulvic acid and a wetting agent into the solution, stirring the solution for a reaction to obtain a solution B, cooling the solution to 30-40 DEG C, adding remaining materials into the solution, stirring the materials for a reaction to obtain a solution C, cooling the solution C to the room temperature, filtering the solution and collecting the filtrate to obtain the foliar fertilizer. The foliar fertilizer can improve wheat resistance to powdery mildew, has good permeability, water-absorbing quality, water-retaining property, strong complexation and chelation ability and surface adsorption ability, improves a fertilizer utilization rate and promotes wheat growth.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a foliar fertilizer for improving wheat powdery mildew resistance and a preparation method thereof. Background technique [0002] Wheat powdery mildew is one of the important wheat diseases caused by powdery mildew graminearum, which can manifest symptoms throughout the wheat growth period. The pathogen can infect the aboveground organs of wheat plants, but mainly the leaves and leaf sheaths. After the wheat leaves are infected, the respiration intensity increases and the photosynthetic efficiency decreases, resulting in a decrease in dry matter accumulation. Mildly diseased fields reduce production by 5% to 10%. Field production was reduced by more than 20%. Wheat powdery mildew is one of the three major diseases that occur widely and seriously in the world. In recent years, it has occurred and prevailed in nearly half of the wheat fields in China, especially in...
