Abstract

The invention discloses synergistic lignin apple special-purpose fertilizer and a preparation method thereof and belongs to the technical field of agricultural fertilizer. The synergistic lignin apple special-purpose fertilizer is composed of 200 to 600 parts of urea, 60 to 300 parts of monoammonium phosphate, 300 to 800 parts of potassium sulfate, 3 to 30 parts of lignin, 3 to 30 parts of ferrous sulfate heptahydrate, 3 to 25 parts of zinc sulfate monohydrate, 0.2 to 15 parts of boric acid and 0.2 to 15 parts of EDTA chelated calcium. The formula of the synergistic lignin apple special-purpose fertilizer is reasonably designed according to the law of apple growth. The synergistic lignin apple special-purpose fertilizer contains nitrogen, phosphorus and potassium and the trace elements needed for the growth period of the apples. Under action of lignin, fertilizer nutrient release satisfies nutrient demands in the apple growth period. The preparation method utilizes high tower spraying granulation, builds a mathematical model through a tower inner pressure field, a temperature field and particle temperature change and movement locus, realizes a metering precision and effectively controls content of lignin fertilizer biuret.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer with synergistic lignin for apples and a preparation method thereof. Background technique [0002] Apple belongs to Rosaceae, a deciduous tree, native to my country, with a cultivation history of more than 2,000 years, and is the crown of the four major fruits in the world. There are four major production areas for apples in China: the Loess Plateau, the Bohai Bay, the old course of the Yellow River and the cold and cool highlands in the southwest. Among them, the Northwest Loess Plateau and the Bohai Bay production area account for 44% and 34% of the country's total apple cultivation area, respectively 49% and 31%, the export volume accounts for more than 90% of the country. China is the world's largest apple producer and consumer, with apple planting area and output accounting for more than 40% of the world's total, occupying an important ...
