Special control-release fertilizer for resin coated bagasse and preparation thereof

Abstract

The invention relates to a special controlled-release fertilizer used for sugarcane and a manufacturing method thereof. The fertilizer is made by compounding 6 per cent thermoplastic resin-coated potassium nitrate, 7 per cent thermoplastic resin-coated potassium nitrate, 5 per cent thermoplastic resin-coated ammonium phosphate, 4 per cent thermoplastic resin-coated urea, 5 per cent thermoplastic resin-coated urea, 6 per cent thermoplastic resin-coated urea, 8 per cent thermoplastic resin-coated urea, potassium sulfate compound fertilizer, etc. The special controlled-release fertilizer used for sugarcane of the invention is manured once before sowing the sugarcane and the dressing is avoided; the invention has a good effect on increasing yield and can raise the utilization ratio of the fertilizer and save labor.

Description

technical field

[0001] The invention relates to a method for producing a special controlled-release fertilizer for crops by using a thermoplastic resin coating, in particular to a special controlled-release fertilizer for resin-coated sugarcane and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique

[0002] Sugarcane is an important raw material for sugar production. In 2003, the world's total sugar production was 145.6 million tons, of which 70% was made of sugarcane. my country is an important producer of sucrose. In 2002, the planted area of ​​sugarcane was 121 hectares, ranking third in the world. Sugarcane is also a high-yield bioenergy crop with high biomass and high sugar content, which can be used not only for sugar refining, but also for direct production of alcohol. With the continuous development of science and technology, as an important energy crop, sugarcane has great development potentia...
