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 sulfur-coated and modified epoxy resin-coated controlled-release fertilizer special for chrysanthemums and a preparation method thereof, and belongs to the technical field of slow / controlled-release fertilizers. Background technique [0002] Chrysanthemum is one of the four major seasonal flowers and ten famous flowers in our country. Known as the gentleman in the flower since ancient times, he has various poses and elegant character. Chrysanthemum is native to my country and has a history of more than 2,000 years of cultivation. There are many varieties of chrysanthemums, which are excellent flower species for beautification of urban and rural areas. With the development of my country's urbanization process and the increase of people's leisure time, the establishment of leisure places and festival celebrations will require more chrysanthemums to dress up, so chrysanthemum cultivation will have further development. [0003] The ch...
