Efficient cultivation slow-release fertilizer for late-maturing citrus and preparation method thereof

Abstract

The invention discloses an efficient cultivation slow-release fertilizer for late-maturing citrus. The efficient cultivation slow-release fertilizer comprises the following components in parts by weight: oyster shuck, polylactic acid, nanometer attapulgite powder, sticky mineral humic acid powder, edible mushroom residue, bagasse, peat soil, oil-extraction waste, zinc-rich saccharomycete, actinomycetes, gamma polyglutamic acid, amine acyl ester, rice bran vinegar liquid, a defined amount of hydrogen peroxide, a defined amount of ammonium hydroxide and a defined amount of water. According to the invention, the edible mushroom residue, the bagasse, the peat soil and the oil-extraction waste are mixed with nutrient substances and then are fermented and prepared into an enveloping slow-release fertilizer; the fertilizer is rich in fermented micro-molecule substances, is rich in nutrition, can be conveniently absorbed and utilized by plants and is capable of boosting the growth and increasing the nutrition of the citrus; the gamma polyglutamic acid, the amine acyl ester, the rice bran vinegar liquid growth regulator and the accelerant are used for boosting the metabolism of the citrus, increasing the resistance of the citrus and increasing the quality of the late-maturing citrus; and the enveloping fertilizer disclosed by the invention has the advantages of wide material source, low cost, simple preparation process and operation, obvious effect and wide application and popularization.

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 late-maturing citrus cultivation 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 im...
