南酸枣高位嫁接技术研究

Study on Top Grafting Technique of ChoerospondiasAxillaris

文章将南酸枣(Choerospondias axillaris)作为果用经济林进行研究。以5~10年生南酸枣雄株或已嫁接的南酸枣雌株为砧木,采集已选育的南酸枣优良母树的枝条为接穗,春季在离地1~2 m处用腹接法嫁接改良品种。2011~2014年在江西省崇义县连续4年嫁接89株,平均嫁接成活率达84.9%,说明可以采用高位嫁接技术对南酸枣低产低效林进行改造。

Choerospondiasaxillaris is considered as economic forest for fruit utilization. The 3-10 years of male plants or grafted female plants and the branches of the fine selectedfemale tree were used as stoekand scion respectively to improve variety with side grafting at the height of 1-2 meters from ground in spring. During the four years from 2011 to 2014, 89 plants were grafted in Chongyi County, Jiangxi Province, and the average survival rate was 84.9%. Consequently, topgraffing technique can be used to improve the Choerospondiasaxillaris forests that are of low yield and low efficiency.
