63杨表现出生长期长,生长快,抗性强等优良性状.但栽植成活率特别低,为了提高63杨的栽植成活率,我们在西沙大队对63杨进行了栽植试验,取得了较好的结果.1979年3月16日栽植103株,1979年8月调查成活102株,成活率达99%.我们的做法是:1.随起随栽,使苗木免于失水和遭受冻害.2.严格按照杨树新无性系品种的栽培
63 Yang showed good growth characteristics such as long growth period, fast growth, strong resistance, etc. However, the survival rate of planting was particularly low. In order to improve the survival rate of 63 Yang, we conducted the planting experiment on 63 Yang of Xisha Brigade and achieved better Results 103 strains were planted on March 16, 1979, and 102 survived in August 1979. Survival rate was 99% .Our approach is as follows: 1. Seedlings will be protected from water loss and frost damage as they grow. In strict accordance with the cultivation of new poplar clones
