椪柑高接换种的接枝方法研究

A Grafting Method of Chinese Citrus for Improving Variety Quality

通过对中间砧的不同角度、不同接芽方位、不同粗度接枝进行高接试验。结果表明:8年生枳砧普通从江椪柑高接改换从江椪柑良种少核株系,切接高度可选择在1～1.5m,切接角度0°～70°,接枝切面近靠主干一侧,并以距主干角度0°～70°且直径大于1.5cm以上的粗壮接枝开砧为优。

The different angle, grafting bud orientation and diameter of the intermediate rootstock were tested to improve the quality of Congjiang chinese citrus. The results show that the Congjiang chinese citrus with a small number of seed can be bred from the common Congjiang chinese citrus by selecting 1 ～ 1.5 cm grafting height, 0°～70° of grafting angle and cutting orientation near the side of main stem with over 1.5 cm diameter.
