摘要
杨树品种不同,其适应性也不同,育苗存活率会有所不同,以此为指导,通过对83个杨树品种在同一条件下的育苗对比实验,结果表明,黑杨派高于白杨派和胡杨派;黑杨派中存活率在80%以上的达87.1%,存活率90%以上的占81.4%,存活率达100%的占72.9%;白杨派系中存活率最高的为银×新,达100%,占白杨派的8.3%,其次为银白杨90%,存活率在70%以上的只占白杨中的58.3%;胡杨派扦插成活率为0。
Different poplar species have individual adaptation and survival rate. Contrasting 83species of poplar under the same condition, the results showed that the survival rate of Aigeiros is higher than that of Leuces; Of the Aigeiros, the survival rate above 80 percent level accounted for 87. lpereent among the species of Aigeiros, above 90 percent level accounted for 81.4 percent, above 100 percent level reached 72.9 percent. Of the Leuces, the survival rate of Yin x Xin is the highest which reached 100 percent and accounted for 8.3% percent among the species of Leuces, the survival rate of Populus alba reached 90 percent, And the species whose survival rote above 70 percent reached 58.3percent only.
