Abstract

The present invention relates to a peony specialized controlled releasing fertilizer and the preparing method. The fertilizer is obtained by recompounding the components of thermoplastic resin coated urea, thermoplastic resin coated ammonium phosphate, potassium muriate complex fertilizer and the like with different coating quantities. The peony specialized controlled releasing agent of the invention is one-time applied before the sprouting of peony in spring and the injury to the root system of the peony is avoided in multi-time fertilizing, and the fertilizer has the advantages of saving labor and force, increasing the utilization efficiency of the fertilizer, stable nutrition providing and increasing the quality of the flower.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for peonies coated with thermoplastic resin and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Peony is a traditional famous flower in China and a treasure among flowers. It has the reputation of "king of flowers" and "national beauty and heavenly fragrance". Has always been loved by the world. The cultivation of peony not only beautifies the environment, but also provides important support for my country's tourism and cut flower industries. At present, my country has formed large-scale peony production bases and parks such as Luoyang and Heze. [0003] Peony is a perennial woody deciduous flower with a certain ability to store and regulate nutrients in the body. In the annual growth cycle, it has no obvious peak of nutrient absorption. The peony pursues the quantity and quality of flowers as its go...
