在吉林省双辽黑钙土型沙土上建立品种杨基因收集圃并进行适应性栽培试验,结果表明:在88个品种(系)中,苗期(1 a生)成活率大于对照白城小黑杨(85.3%)的有10个品种,分别为晚花杨(94.0%)、新生×小黑52杨(91.3%)、白城41号杨(88.7%)、83-25杨(87.4%)、莫斯科加拿大杨(86.7%)、加×美杨(86.7%)、88-04杨(86.7%)、98-33杨(86.7%)、黑林2号杨(86.7%)、小×钻杨(85.6%)。半轮伐期(12 a生)保存率大于对照白城小黑杨(85.33%)的有2个品种,分别为7915501杨(91.67%)和白林3号杨(87.50%);与对照表现持平的有1个品种,即新生×小黑52杨(85.33%)。
The cultivation of Yang gene in Shuangliao Chernozem-type sandy soil in Jilin Province was carried out and the adaptive cultivation experiment was conducted. The results showed that in 88 varieties (lines), the survival rate of seedlings (1 year old) was greater than that of control Baicheng black There were 10 varieties of Yang (94.3%), 91.3% of Xinyang black, 88.7% of Baicheng 41, 87.4% of 83-25 of Yang (85.3%), (86.7%), 88-04 Yang (86.7%), 98-33 Yang (86.7%), Heilin 2 (86.7%), 85.6%). There were two varieties with semi-rotation (12 a) survival rate greater than that of the control (80.33%), which were 7915501 poplar (91.67%) and Bailing No.3 poplar (87.50%), respectively. Compared with the control There are 1 varieties, that is, newborn × black 52 Yang (85.33%).
