摘要
从1983年起,对毛白杨、河北杨的扦插繁殖育苗及其机理进行了研究,研究出“多代循环繁殖新方法”,无需任何处理,也无需地膜覆盖,使大田育苗成活率稳定在80％左右;同时研究出快速、简便、繁殖系数高的优树根萌条培育新技术,为毛白杨、河北杨优树的无性系测定、无性系育种和无性系造林创造了条件。
A new circultion method of vegetative propagation of Populus tomentosa and Populus hopeiensis have been studied and developed for 6 years. This method. of propagation does not need any chemical treatment and plastic cover on the nursery bed for cuttings. The survial percent age of cuttings of the two poplars species steadily keeps 80％ or over. And a new root shoot-suckers-reproduction method has been made. The successful propagation of the poplars provided much progress for clonal test, clonal breeding and clonal afforestation of the selected trees of the two poplar species.
