摘 要 ：本试验旨在针对1个早衰低产、行将淘汰的芒果老果园进行几种更新改造模式的探索性试验，以为景谷全县现存数万株芒果老果树的更新复壮作出示范和提供科学依据。自1991年采果后，对此 10 hm2 2064株的老果园分别采取轻度更新、隔行更新、强度更新与轻度修剪 4种模式，并配合以其它农艺措施（定期防治病虫害、坡改台、增施肥料）加强管理。在原有大芒果树仅保留1100株的情况下，1993年全园总产量达 44 360 kg，为改造前 1年的10倍和改造前3年平均年产量的21.65倍。几种改造模式在目前的增产效果为：轻度更新＞隔行更新＞轻度修剪＞强度更新。强度更新的嫁接株自嫁接后两年开始进人投产期。

Abstract:In order to rejuvenate aged mango trees with low output and nearly obsoletation, an experiment was carried out in Daqiaotou mango plantation, Jinggu County, which could provided some scientific data for rejuvenating thousands of aged Mango trees in Jinggu County. Since the fruits of aged mango trees were collected, four kinds of experiment modes, namely strongly rejuvenating, lightly rejuvenating, rejuvenating one every two rows of aged mango trees and lightly pruning, were carried out in the aged mango plantation with a area of l0 hm2 totally including 2064 aged mango trees.
