芒果劣种树不同改接换冠方法对比研究

Comparison Study on Different Grafting Change Method of Poor Quality Mango

对芒果劣种树改接换冠的不同树体状况、不同嫁接方式、方法进行了对比试验观察,指出针对不同树体状况和不同改接目的应采取的改接换冠方法。结果表明:高位换种和低位换种均可取得较好的效果。从短期效益看,高位换种+断根处理效果更好;但从长远效益看,低位换接更便于树体的更新和管理。改接换冠同时进行根系更新对树龄较大的果树尤为重要。

Comparison trial observation was conducted to different the mango trees conditions with canopy renewal, different grafting methods, pointed out that for the different trees and different aims to grafting trees. The results showed that high-level and low-level renewal could be achieve better results. From the short-term efficiency, high renewal＋root cutting achieved better results ;however, from a long-term efficiency,low-level renewal made it easier for tree-update and management. To renewal the crown plus root cutting was particularly important to update the older fruit trees.
