Abstract

The invention discloses a special functional biological sustained-release fertilizer for blueberry, and belongs to the technical field of agricultural fertilizers. The fertilizer is prepared from compound microbial inoculum and an inorganic fertilizer, wherein the compound microbial inoculum consists of microbial strains and a culture medium; the inorganic fertilizer consists of ammonium sulfate, potassium sulfate, monoammonium phosphate, humic acid, ferrous sulfate and EDTA chelated trace elements. The special functional biological sustained-release fertilizer for blueberry is prepared according to nutritional characteristics and fertilizer requirement law of blueberry by combining the disease treatment strategy based on the soil micro-ecosystem, contains microbial inoculum and pre-treated humic acid, is reasonable in nutrition proportion, integrates the functions of preventing and treating soil borne diseases, increasing the crop yield, improving the crop quality and improving the soil micro-ecology, has a high fertilizer utilization rate, and has remarkable economic, social and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for functional biological slow-release blueberries. Background technique [0002] Blueberry is a berry shrub with high economic value, belonging to Rhododendronaceae and Vaccinium. The blueberry fruit is blue, nearly round, and the flesh is delicate. The unique anthocyanins, safflower, folic acid, ellagic acid and other substances in the fruit have anti-aging, improve eyesight, soften blood vessels, and reduce the incidence of cancer. Function, known as "21st century functional health berries", and is listed by the International Food and Agriculture Organization as one of the five health foods for human beings. [0003] Blueberries are shallow-rooted plants with thin, underdeveloped roots and no root hairs. It likes soil that is acidic, soft, loose and breathable, and rich in organic matter. Generally, the soil pH is required to be 4.5-5.5,...
