摘要
[目的]选育优质丰产杨树品种品系.[方法]根据育种目标,引进青杨派、黑杨派、白杨派杨树品种品系200个品种,在对引进品种进行苗期试验的同时,选出21个苗期表现较好的苗木定植品种混交栽培试验林,通过对各品种品系生长量、干形、冠幅、侧枝粗度、冻害、病虫冻害等综合指标进行评定,筛选表现突出的优良品种.[结果]通过综合评定,14个黑杨派品种品系中,中林三北1#、78-133树冠窄,生长量大,是农田防护林的理想树种.黑杨派品种中林、中林23、54、78-8、78-133等,白杨派品种银白杨、林场银×新、银×新12#、84K、101等品种,可作为速生品种在工程造林中推广.白杨派品种84K、101、林场银×新、银×新12#生长迅速,干形通直,不飞絮,可用作城市绿化树种.[结论]该研究可为伊犁林业工程造林提供参考.
Abstract
[Objective]To breed of high quality and high yield of Populus L.[Method]According to breeding objectives, tacamahaca, black poplar,populus varieties of 200 varieties in seedling test of varieties were introduced at the same time, 21 varieties were selected to cultivate test forest,superior varieties were selected by evaluating the varieties growth, stem form, crown width,branch diameter, freezing, frost and other diseases.[Result]According to the comprehensive evaluation, Zhonglinsanbei 1#, 78-133 in 14 black poplar varieties was narrow, the growth was large, and it was the ideal species of farmland shelter forest.Zhonglin, Zhonglin 23, 54,78-8,78-133 in black poplar, Populus alba L, Linchang yin×xin, yin×xin 12#, 84K, 101 in tacamahaca were not only growth rapidly,stem form straightly,so it can be used as a city greening tree species.[Conclusion]The study can provide a reference for afforestation of forestry engineering in Yili.
