Abstract

The invention relates to a special controlled release fertilizer for poinsettia and a preparing method thereof. The fertilizer is obtained by compounding modified epoxy resin coated urea with different coating amount, modified epoxy resin coated ammonium phosphate, modified epoxy resin coated potassium nitrate, modified epoxy resin coated sulphate-potassium magnesium, diammonium nitrate, etc. The special controlled release fertilizer for poinsettia is applied during transplantation, has advantages of saving labor and power, improving fertilizer availability ratio, and satisfying request of nitrogen, phosphorus and kalium during different growth periods.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for poinsettia coated with modified epoxy resin and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Poinsettia is native to Mexico and is an ornamental flower. It is green and red, dazzling and intoxicating. The poinsettia has a long flowering period, starting from December, and the bracts and flowers can last until February and March. It is not only a good ornamental flower, but also one of the cut flowers. In Europe and America, poinsettia is an indispensable flower variety for Christmas decoration, so it is also called Christmas flower. In southern China, poinsettias can be planted in the ground. On both sides of the Yangtze River and the area north of it, potted plants are often used for the convenience of overwintering. In recent years, the planting of poinsettia in my country has gradually incre...
