摘要
光叶楮(Broussonetiapa pyrifera(l)vent)是具有造纸、饲料、纺织等多用途的速生、高经济价值的树种。本文通过对不同规格的光叶楮根段插穗扦插育苗试验结果进行总结和分析,阐明了根段等级与苗木平均高度、成苗率、不同时段的出芽率及初出芽期的关系,并建议生产上采用根径在0.5 cm以上的根段作插穗,可获得较高的成活率。
Broussonetia papyrifera is a kind of fast growing tree with multi-purposes for paper-making,animal feed,textile and other economic uses.Based on the experiments,different specifications for breeding of Broussonetia papyrifera by root segment cuttings were summarized in terms of cutting length,diameter,their germination rates and seedling height.The length of 0.5 cm root segment is recommended for breeding usage,which can generate higher survival rates according to the experiment.
