Abstract

The invention relates to a special controlled-release fertilizer for sulphur resin coated fast-growing poplars and a preparation method thereof. The special controlled-release fertilizer for sulphur resin coated fast-growing poplars is prepared with sulphur resin coated urea of different coating volumes, sulphur resin coated ammonium phosphate, potassium nitrate compound fertilizer, etc. The special controlled-release fertilizer for sulphur resin coated fast-growing poplars is applied in one go for all after leaf falling in autumn, thereby saving manpower and strength and enhancing the planting level of fast-growing poplars. The special controlled-release fertilizer for sulphur resin coated fast-growing poplars can meet the demand for nitrogen, phosphor, and potassium by fast-growing poplars in the annual growth period, thereby increasing the yield effectively.

Description

technical field [0001] The invention relates to a sulfur-added resin-coated fast-growing poplar special controlled-release fertilizer and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Poplar grows fast, has strong adaptability, is easy to reproduce, has high wood yield and short rotation period, and is an ideal tree species for building fast-growing and high-yield timber forests. Poplar is also widely used in plain greening and shelterbelt construction. At present, my country's poplar plantation area is about 6 million hectares. The supply of virgin forest timber in my country is decreasing day by day, and the consumption of timber for civilian use, packaging industry, and papermaking industry is increasing year by year. The construction of ecological engineering and sand prevention and control projects require a large amount of poplar afforestation. Therefore, in the next period of time...
