摘要
在柳树引种对比试验的基础上 ,对所选出的 5个生长快、干形好、抗逆性强的品(系 )种于 1 996～ 1 998年在全省 4个气候类型区进行了区域性试验。结果表明 :J1 72、J1 94、J36 9柳除武威试点外 ,其余各点均表现出极强的速生性 ,定植 3年后最大单株高 9.9m,最大胸径 1 2 .8cm;准噶尔柳和青刚柳在武威和临夏表现出良好的速生性。 5个品系在临夏杨柳蛀干害虫为害区 ,经 1
By introducing and making comparative experiment of Salix,5 varieties of Salix,which grow fast, have good sterm form and strong resistance, have been planted in 4 climate areas of Gansu from 1996 to 1998.
