Abstract

The invention relates to a special controlled release fertilizer for chrysanthemum 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, potassium chloride compound fertilizers, etc. The special controlled release fertilizer for chrysanthemum is applied during transplantation, has advantages of saving labor and power, improving fertilizer availability ratio, satisfying request of nitrogen, phosphorus and kalium during different growth periods, applying nitrogenous fertilizer stably, and avoiding watershoots of chrysanthemum.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for sulfur-coated and modified epoxy resin-coated chrysanthemums and a preparation method thereof, belonging to the technical field of slow / controlled-release fertilizers. Background technique [0002] Chrysanthemum is one of the four season flowers and ten famous flowers in China. Known as a gentleman among flowers since ancient times, he is in various poses and with different expressions and elegant character. Chrysanthemum is native to my country and has been cultivated for more than 2,000 years. There are many varieties of chrysanthemums, which are excellent flower species for urban and rural beautification. With the development of my country's urbanization process and the increase of people's leisure time, more chrysanthemums will be needed to dress up the establishment of leisure places and festival celebrations, so chrysanthemum cultivation will have further development.
