采用夏季修剪或嫩枝扦插采条留条的方法，可以人为地使杜仲抽发扦插二次梢。本文针对这种促梢方法，就二次梢抽梢母枝对二次梢抽梢数、生长量、生根的影响展开的试验，进行了分析和讨论。其结果表明，选用顶梢、树干基部的萌条、树冠中上部外围生长健壮、生长角小的新梢作母枝，可以获得数量较多、质量较好的扦插用二次梢。 The use of summer pruning or shoot cuttings sticking method, you can artificially make Eucommia cuttings second shoot. In this paper, for this method of promoting shoots, the effects of secondary shoots shoots on secondary shoots, growth and rooting were analyzed and discussed. The results showed that the selection of top shoots, stems of the base of the sprout, the crown of the upper periphery of the robust growth of small growth angle for the shoots of young shoots, you can get a larger number of better quality cuttings with two shoots.
