Abstract

The invention relates to a fertilizer special for carrot and the preparation method thereof, which is prepared with sulphur resin coated urea, 4 percent of thermoplastic resin coated urea, 3 percent of thermoplastic resin coated ammonium phosphate, 3 percent of thermoplastic resin coated potassium nitrate, diammonium phosphate, etc., compound preparations. The fertilizer special for carrot of the invention is adopted once applied fertilizer before the carrot is sowed, thereby enhancing the fertilization effect, saving manpower and efforts, meeting the requirement for nitrogen, phosphor and potassium by carrot in the annual growth period, delivering a stable nitrogen fertilizer supply and being beneficial to a high yield and yield increase of carrots.

Description

technical field [0001] The invention relates to a carrot special fertilizer produced by using sulfur-coated urea, thermoplastic resin-coated urea, thermoplastic resin-coated ammonium phosphate and thermoplastic resin-coated potassium nitrate and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Carrot is a traditional vegetable in our country. It is rich in sucrose, glucose, dietary fiber, etc., especially carotene, which has a good therapeutic effect and has always been known as "little ginseng". Carrots are easy to cultivate, high in yield, durable in storage and good in economic benefits, and are very popular among growers. With people's increasing emphasis on healthy food and the gradual shortage of labor resources in our country, carrot is a promising vegetable. [0003] Fertilization is an important factor affecting yield and quality in carrot cultivation in addition to variety and water. At present, due to t...
