Abstract

The invention provides a drought-resisting and boll-protecting water-soluble fertilizer and a preparation method thereof. The drought-resisting and boll-protecting water-soluble fertilizer is preparedby mixing urea, fulvic acid, magnesium sulfate, a pretreatment material, a rooting agent and colloidal particles, wherein the pretreatment material is prepared by mixing and grinding mushroom bran, polyvinyl alcohol, potassium sulfate and monopotassium phosphate; the rooting agent is prepared by mixing sodium 2, 4-dinitrophenol, sodium p-nitrophenolate, sodium o-nitrophenolate and naphthylaceticacid; the colloidal particles are prepared by mixing pregelatinized starch, guar gum, EDTA-Zn, EDTA-Mn, EDTA-Fe, boric acid, indolebutyric acid and water at a high speed. The drought-resistant boll-retaining water-soluble fertilizer provided by the invention can realize comprehensive synergy according to the growth requirements of cotton plants in arid regions, so that the cotton plants absorb nutrients in time, physiological bolls are reduced, the humidity between cotton fields is maintained, the drought-resistant purpose is achieved, and the cotton yield is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a drought-resistant boll-preserving water-soluble fertilizer and a preparation method thereof. Background technique [0002] As a heat-loving and light-loving crop, cotton is suitable for planting in loose and deep soil. The three major cotton regions in my country are the Yellow River Basin, the Yangtze River Basin and the Northwest Inland Cotton Region. Among them, Northwest Xinjiang is currently the largest cotton producing area in my country. With the development of cotton planting towards refinement and high yield, functional fertilizers have become the key to ensure sustained high yield. Xinjiang is an arid or semi-arid area, and water and nutrients are the two limiting factors for cotton production. When cotton enters the flowering and boll stage, buds and bolls will fall off, which will affect the yield of cotton. There are many influencing factors th...
