慈溪已有多年种梨的历史,但由于品种老化,病虫害严重,管理粗放,经济效益低下,已有不少老梨园刨掉改种,致使梨生产出现滑坡。据统计,慈溪市1987年有梨园1684亩,到1990年仅剩1096亩,面积下降35％。 黄花梨系浙农大以黄蜜作母本,三花作父本,于1962年育成的杂交新品种。该品种具有生长强健,结果性能强,果实品质好,适应性强,管理方便等特点。慈溪于1986年在精忠缪路开始引种,投产后产品大受市场青睐和消费者的欢迎。为充分利用现有梨树资源,1989年始老梨园通过改接换种更新成黄花梨。至1993年,共改接老梨园380亩,成活率达98％。改接后第2年即投产,一般株产为20kg左右,3～4年后进入盛果期,亩产为4000kg左右。嫁接方法以枝接为主,芽接为辅,嫁接时间以春季为主,并与夏、秋季相结合。改按时需保留10％左右的老品种或将其嫁接成其他品种作为黄花梨的授粉品种。
Cixi has many years of pear history, but due to aging varieties, serious pests and diseases, extensive management, low economic efficiency, there are many old pear planing and replanting, resulting in pear production landslide. According to statistics, there were 1,684 mu of pear orchard in 1987 in Cixi City, leaving only 1096 mu in 1990 with an area decrease of 35%.

The second year after the switch that is put into production, the general strain of about 20kg, 3 to 4 years into the flourishing period, about 4,000 kg per mu. Grafting methods to stick-based, Budding supplemented grafting time in spring-based, and with the summer and autumn combined. To change the time required to retain about 10% of the old varieties or grafted into other varieties as pear varieties of pollination.
