Sustained-release fertilizer taking biomass granular carbon as matrix and specially used for grape and preparation method of fertilizer

Abstract

The invention discloses a sustained-release fertilizer taking biomass granular carbon as a matrix and specially used for grape and a preparation method of the fertilizer. The method comprises the following step of: compounding granular carbon which is prepared from agricultural waste biomass such as corncob, peanut shells, rice husks and an edible fungus matrix and is taken as a matrix material with nitrogen, phosphorus, potassium and other nutrient elements which are necessary to the growth and development of the grape by using the multiple micropores and high adsorption capacity of the granular carbon to prepare a granular biomass carbon-based sustained-release fertilizer special for the grape. The used biomass granular carbon is black biomass granular carbon granules formed after the agricultural waste biomass is subjected to incomplete combustion under the low-oxygen condition, has multiple characteristics similar to those of soil humus, is high in nutrient and water adsorbing and retaining capacity, can stimulate crop growth, and is high in nitrogen, phosphorus and potassium sustained-release performance, so that the sustained-release fertilizer prepared from the biomass granular carbon can effectively meet the requirement of the grape on nutrients in the whole growth period after being applied at one time, has the characteristics of increasing soil fertility, improving a soil structure, achieving high efficiency and environment friendliness, and the like, and is easily popularized and applied to grape production on a large scale.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural fertilizer production, in particular to a special slow-release fertilizer for grapes using biomass granular carbon as a matrix and a preparation method thereof. Background technique [0003] For grape production, both quantity and quality should be paid more attention to. Reasonable fertilization is an important factor to regulate yield and quality. Grapes need to supply nitrogen in a timely and appropriate amount, otherwise, insufficient nitrogen will hinder the formation of chlorophyll, reduce photosynthesis, grow thin, and produce low yield; excessive nitrogen will lead to excessive growth of branches and leaves, poor coloring of berries, low sugar content, and low quality. decline. Grapes require a large amount of potassium, known as "potassium crops". Potassium fertilizers play an important role in promoting berry ripening and coloring, and improving sugar content, flavor and ...
