High-phosphorus base fertilizer and processing technique thereof

Abstract

The invention discloses a high-phosphorus base fertilizer which comprises an inorganic component and an organic component. The nitrogen:phosphorus:potassium mass ratio in the inorganic component is (8-13):(27-33):(4-8). The organic component is composed of beer residues, edible fungus residues, corn flour, a composite microbial inoculant, peat soil and crop powder. The organic component and inorganic component are combined in a mass ratio of 1:(3-4) to prepare the high-phosphorus crop base fertilizer. The high-phosphorus base fertilizer is extruded by countershafts to obtain the granules with the diameter of 3-5cm; the granules have high strength and low caking tendency, can uniformly provide phosphorus for soil and crops, are safe to use without burning the seeds or roots, and have favorable yield increase effect; the application rate per mou is lowered by 9-15%; and the fertilizer efficiency is prolonged by 75-86%.

Description

technical field [0001] The invention relates to a base fertilizer, in particular to a high-phosphorus base fertilizer and its processing technology. Background technique [0002] my country is a large agricultural country. Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. [0003] When phosphorus is deficient, the crops grow slowly, are short and thin, erect, have few branches, and the leaves are small and easy to fall off; the color is generally dark green or gray green, and the leaf margins and petioles often appear purplish red; the root system is stunted, maturity is delayed, and the yield and quality are reduced. When crops are deficient in phosphorus, the symptoms generally start from the old leaves at the base o...
