Problems solved by technology

However, at present, the popularization and application of coated fertilizers has been hindered by reasons such as the high price of the coating material used, the complicated process, and the difficulty in degrading in residual soil. Therefore, a new, efficient, cheap, and biodegradable coating is developed. Osmanthus special controlled release fertilizer is very necessary

Abstract

The invention discloses a chitosan-coated controlled release fertilizer special for sweet osmanthus trees and a preparation method for the fertilizer, and relates to the technical field of controlled release fertilizers special for flowers. According to the nutrient absorption law of the sweet osmanthus trees, the method comprises the following steps of: proportioning 3 percent chitosan-coated urea, 4 percent chitosan-coated urea, 6 percent chitosan-coated urea, urea, concentrated superphosphate, potassium sulfate, zinc sulfate, magnesium sulfate, copper sulfate, borax and filler which serve as specified components, stirring and mixing the components uniformly through a stirring machine, metering, packing, and thus obtaining the controlled release fertilizer. The fertilizer has the advantages of high fertilizer nutrient utilization rate, low environmental pollution due to biodegradability of the coating and low price.

Description

technical field [0001] The invention belongs to the technical field of production of slow- and controlled-release fertilizers special for flowers, and in particular relates to a special controlled-release fertilizer for sweet-scented osmanthus and a preparation method thereof. Background technique [0002] Osmanthus fragrans (scientific name: Osmanthus fragrans, English Sweet Olive), a temperate tree species, is a famous flower variety in my country, has important ornamental value, and is also an important raw material for food industry, flavor industry, and light industry. Because "gui" and "gui" have the same pronunciation, many people in the industry believe that osmanthus is a "tree of wealth and honor" with high economic value. [0003] Osmanthus fragrans is divided into four seasons and autumn osmanthus. Four seasons osmanthus begins to bloom in September and continues until April to May of the next year. Autumn osmanthus blooms mainly in September to October, genera...
