Problems solved by technology

However, frequent trench digging and fertilization increase the labor intensity of farmers, and at the same time cut off a large number of roots, affecting the absorption of nutrients
So far, there has not been any public report of a special controlled-release fertilizer for hawthorn that can well solve the above problems

Abstract

The invention relates to a special controlled-release fertilizer for hawthorn trees and a preparation method thereof. The special controlled-release fertilizer for hawthorn trees is prepared with sulphur resin coated compound fertilizer of different coating volumes, 3 percent sulphur resin coated ammonium phosphate, 5 percent sulphur resin coated potassium nitrate, potassium sulphate compound fertilizer, etc. The special controlled-release fertilizer for hawthorn trees is applied in one go before the budding in spring, thereby reducing the harm of fertilizations to tree roots. The special controlled-release fertilizer for hawthorn trees can meet the demand for nitrogen, phosphor, and potassium by hawthorn trees in the annual growth period, thereby increasing the production effectively.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for hawthorn and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Hawthorn is a deciduous fruit tree in the temperate zone, widely distributed in Europe, the United States and most parts of Asia. However, hawthorn is basically not used as a fruit tree in foreign countries, and it is in a wild state. my country is the origin of hawthorn, with a cultivation history of more than 3,000 years. It is mainly distributed in Shandong, Henan, Hebei, Shanxi, Tianjin, Beijing and other provinces and cities. Hawthorn is rich in nutrition, and the calcium content of the fruit ranks first among all kinds of fruits. Hawthorn also has medicinal value. In recent years, due to the development of processing industry and foreign trade, the cultivation of hawthorn in my country has been further developed. [0003] Hawthorn h...
