Hawthorn tree is long-term growth, without management, until the mid-70s, only gradually into a park, strengthen the cultivation and management, have conducted some research work. However, the law of the absorption of hawthorn fertilizer, fertilizer technology and did not conduct in-depth study, has not been reported in the country. Extensive production of fertilizers, more sets of apple tree fertilization methods, has a certain blindness, tree growth and development are not coordinated, low yields, poor quality of fruit, can not meet the needs of people’s lives and economic development.
