Abstract

The invention discloses a special controlled-release fertilizer for sulphur resin coated chestnut and a preparation method thereof. The special controlled-release fertilizer for sulphur resin coated chestnut is prepared with 4 percent sulphur resin coated compound fertilizer, 3 percent sulphur resin coated compound fertilizer, 3 percent sulphur resin coated urea, 5 percent sulphur resin coated potassium sulphate compound fertilizer, etc. The special controlled-release fertilizer for sulphur resin coated chestnut is applied in one go before the budding in spring, thereby reducing the harm of fertilizations to chestnut roots. The special controlled-release fertilizer for sulphur resin coated chestnut can meet the demand for nitrogen, phosphor, and potassium by chestnut in the annual growth period, thereby increasing the production effectively.

Description

technical field [0001] The invention relates to a method for producing a special controlled-release fertilizer for crops by using a sulfur-added resin coating, in particular to a special controlled-release fertilizer for chestnuts coated with sulfur and a resin coating and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Chestnut fruit is rich in nutrition, sweet in taste, and also has therapeutic effects, and is deeply loved by people all over the world. However, due to the spread of chestnut blight and the shrinking planting industry of European chestnut and American chestnut, the cultivated area tends to decline. Although Japanese chestnuts have increased slightly, their disease resistance and nut quality are not as good as those of Chinese chestnuts. Chestnut is the original fruit tree of my country, and it has a long history of cultivation, more than 6,000 years ago. With the research ...
