High-efficiency slow-release fertilizer used for fragrant fruit lotus root and preparation method thereof

Abstract

The invention discloses a high-efficiency slow-release fertilizer used for fragrant fruit lotus root. The fertilizer contains the following ingredients: oyster shell, sulphited castor oil, cane sugar, white carbon black, serpentine powders, rice hull ash, grapevine powder, plant deodorizing bacteria, saccharomycetes, ganoderma lucidum, butanedioic acid, nitrogen humate, black pepper extract, grape seed extract, Brassinosteroid, aproper amount of hydrogen peroxide, a proper amount of ammonia water, etc. By fermentation of serpentine powders, rice hull ash and grapevine powder in cooperation with nutrients, a coated slow-release fertilizer is prepared. The fertilizer itself is rich in organic matter and mineral elements, has rich nutrients, and has no peculiar smell. With the adoption of a coating layer capable of oxygen supply and dynamic regulation of pores, the fertilizer has long time of fertilizer efficiency, can release organic matter for a long time, and can promote metabolism of lotus root, promote growth and development of lotus root and inhibit infectious microbes in the growth environment. By the use of the fertilizer, quality of lotus root is guaranteed, oxidation resistance and brittleness are enhanced, and high-efficiency cultivation is realized. The fertilizer can be widely applied and promoted.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a high-efficiency slow-release fertilizer for fragrant fruit lotus root and a preparation method thereof. Background technique [0002] As an important agricultural material, chemical fertilizers have played a pivotal role in increasing food production. Although my country has a large amount of fertilizer, its fertilizer use efficiency is far lower than that of developed countries in the world. In my country's traditional fertilizer fertilization, the utilization rate of nitrogen fertilizer is 30% to 35%, the seasonal utilization rate of phosphorus fertilizer is 8% to 20%, and the utilization rate of potassium fertilizer is about 50%. Most of the nutrients are lost in the air and groundwater with leakage and evaporation. , not only waste serious, but also cause soil, air, groundwater and other environmental pollution. Therefore, modifying fertilizers to improve f...
