Efficient slow-release fertilizer capable of promoting strawberry growth and development and preparation method thereof

Abstract

The invention discloses an efficient slow-release fertilizer capable of promoting growth and development of strawberries. The fertilizer is prepared from the following components in parts by weight: oyster shell, graystone nanocellulose, carbon aerogel, activated nano yellow subsoil, silkworm excrement, bean cake dregs, peanut dregs, distiller's yeast, wine-related yeasts, urease inhibitors, ammonium bicarbonate, vegetable amino acids, compound sodium nitrophenolate, dicyandiamide, honey, brassinolide, a proper amount of hydrogen peroxide, a proper amount of ammonium hydroxide and the like. The silkworm excrement, the bean cake dregs, the peanut dregs and the distiller's yeast are adopted to match with a plant growth regulator, thus the coated slow-release fertilizer is prepared by fermenting, the fertilizer contains rich organic matters and is nutrient-rich, a coat film layer capable of supplying oxygen and dynamically regulating pores is adopted, the fertilizer effect time is long, nutrients can be released for a long time, cell viability of the strawberries can be improved, plant growth and development are accelerated, root and seedling growth is improved, the yield is increased, the ability of tolerating adversity is enhanced, efficient cultivation is realized, and the fertilizer can be widely applied and popularized.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a high-efficiency slow-release fertilizer capable of promoting the growth and development of strawberries 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, ...
