摘要:

本文是在引选育杨树无性系苗期综合评价基础上,对苗期选出的优良无性系进行造林综合评价的初步结果。经5~8a造林对比试验,并通过5项主要因素指标评价和2项次因素指标综合评价,初步选出了23个无性系。其中,建10#(P.×euramericanacv’ND182)、小黑8401(P.simonii-Baicheng×P .nigra-Aeriai8401)、白林2#(P.Nigra×P.pyramidalis)、欧美I-M (P .euramericanacl.“I-M”)、中林86-22(P.Zhonglin 86-22)、黑林1号(P.xiaohei×P.p1 5Acl.)、辽杂2#(P.simonii×Xiaozhuannica cl.Liaoza-2 )、拟青×山海关(P.nigra×P .deltoides cv.“Shanhaiguan”)、中赤黑小(P.nigra×P.simonii cv Zhongchi’)、法库1#(P.simonii×Xiaozhuannica cl.’Faku-1 )等,其生长量明显超过当地主栽树种白城41#(P.simonii×Xi aozhuannica cl’Baicheng-41)和白城2#(P.simonii×Xiaozhuannica cl’Baicheng \|2 ) ,抗寒、抗病、抗虫性、树干干型也都表现突出,适合科尔沁沙地有选择性种植和推广。

Abstract:

Since 1989,FAO project GCP/CPR/009/BEL of the Three North Shelterbelt Programme has assisted in introducting more than 650 poplar clones.This material has been stored in clonal banks,and parts of it is being tested in field clonal trials in different sites of Korqin sandy lands.This paper summarizes the preliminary results from four main trials.23 clones had been selected by multiple evaluation consisted of 5 main tactor indexes and 2 secondary tactor indexes from contrast trials based on primary aelection.The results showed that the growth increment of clones Jian 10# (P.×euramericana cv' ND182),Xiaohei 8401 (P.simonii-Baicheng × P.nigra-Aertai 8401),Bailin 2#(P.nigra × P.pyramidalis),Euro-American I-M (P.euramericana cl.“I-M”),Zhonglin 86-22(P.Zhonglin 86-22),Heilin 1#(P.xiaohei × P.p15A cl.),Liaoza 2#(P.simonii × Xiaozhuannica cl.Liaoza-2),Nixing × Shanhaiguan (P.nigra × Puplus deltoides cv.“Shanhaiguan”),Zhongchi Heixiao(P.nigra × P.simonii cv Zhongchi'),Faku 1#(P.simonii × Xiaozhuannica cl.Faku-1),etc.,was obviously beyond Baicheng 41#(P.sinonii × Xiaozhuannica cl.Baicheng-41)and Baicheng 2#(P.simonii × Xiaozhuannica cl.'Baicheng-2),which were the local main tree species.Meanwhile,cold resistance,disease and pest resistance,and stem form of these clones also behave prominently.So the above clones are very suitable for planting and extending in Korqin sandy land.
