利用高接换头进行桃树换优,目前通用的方法是插皮枝接。此法操作技术复杂,费工费时,较细砧木韧皮部较薄不适于插皮枝接。2011~2013年在吐鲁番市葡萄乡木纳尔村对8年生的毛桃进行了劈接、贴芽接试验(嫁接品种为早熟的丽春油桃),效果较好。劈接成活率80%~90%,贴芽接成活率85%~95%,均比插皮枝接成活率高50%~60%。劈接和贴芽接方法如下。①嫁接于树液开始流动期(2月下旬至3月上旬)开始,适宜嫁接期为2月下旬至3月底。②良种接穗于萌芽前15~30天(1月中旬至萌芽前)采集,剪取树冠外围健壮充实 The use of high interchange peachtree replacement, the current common method is to cut the skin branches. This method of operation is complex, time-consuming work, thin rootstock phloem is not suitable for thin cuttings connected. From 2011 to 2013, 8-year-old peaches were split in buds and sprouted in buds in Muhar Village, Tujia City, Turpan City. The grafted varieties were premature Li-neeng nectarine and had a good effect. The cleavage survival rate of 80% to 90%, bud budding survival rate of 85% to 95%, than the cutaneous grafting survival rate of 50% to 60%. Cleavage and budding connection method is as follows. Grafting in the sap flow began (late February to early March) began, the appropriate grafting period from late February to the end of March. ② seed scion in the bud 15 to 30 days before (mid-January to bud before) to collect, cut crowns outside the robust
