Problems solved by technology

The chemical fertilizers currently used are mainly quick-acting fertilizers, which dissolve quickly after being applied to the soil, and the nutrient concentration in the soil is too high in a short period of time, especially nitrogen fertilizer, which is not good for high and stable cherry yields.
The current solution to this problem is to increase the frequency of fertilization and reduce the amount of fertilizer used each time, which has brought two problems. One is to increase the labor intensity of farmers; the other is to dig trenches and fertilize during the growing season of cherries. Root system, which is not conducive to the absorption of nutrients
There is no report on the special controlled-release fertilizer for cherries and its preparation method at present

Abstract

The invention relates to a special controlled-release fertilizer for cherry and a preparation method. The special controlled-release fertilizer can be prepared by the ingredients of thermoplastic resin-coated potassium nitrate, epoxy resin-coated compound fertilizer, thermoplastic resin-coated urea, potassium sulphate compound fertilizer and diammonium phosphate. The special controlled-release fertilizer for cherry can be fertilized with organic fertilizer combining with deep soil turning before winter; the topdressing is unnecessary; and the yield result is better; the utilization of fertilizer can be increased with labor saving.

Description

technical field [0001] The invention relates to a method for producing a special controlled-release fertilizer for crops by using a thermoplastic resin coating, in particular to a special controlled-release fertilizer for cherries coated with a thermal resin and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] There are more than 60 countries in the world to plant and produce cherries, mainly concentrated in Europe and America. By 2003, the world's cherry cultivation area was nearly 400,000 hectares, with an output of more than 1.7 million tons. In recent years, my country's cherry cultivation has developed rapidly. The current cultivation area is 26,000 hectares, with an output of 120,000 tons. The price of cherries is high, and the cultivation and management are easy. It is a high-profit crop in the planting industry. At the same time, big cherries are also my country's advantageous expor...
