银白场是南疆营造用材林最优良树种之一,在阿克苏地区生长良好.但大面积造林时,用扦插育苗方法供应苗木,比较困难.几年来,扎木台林场和自治区林科所试验小组以大田生产和小面积试验相结合方式,进行了银白杨扦插育苗.三年来大田生产基本上是失败了,惟有小面积试验,因用不同扦插季节和插穗的冬藏处理,成活率显著提高.1960年秋及1961年春计扦插64亩,成活最低者为13.54%,最高者为57.5%(每亩扦插30,000株,成活17,250株).至1961年9月,苗木生长健壮,
Yin Bai field is one of the finest species of timber in southern Xinjiang, which grow well in Aksu region, but it is more difficult to supply nursery stock by cutting propagation when large-scale afforestation.For several years, the experimental group in Zamutidai Forest Farm and Autonomous Region Field production and small-area test, the poplar cuttings were planted and the field production was basically failed in the past three years, but the survival rate was significantly increased in the small-area test because of the winter cuttings with different cutting seasons and cuttings. In the autumn of 1961 and the spring planting of 64 mu, the lowest survivor was 13.54% and the highest was 57.5% (30,000 cutting per acre and 17,250 surviving plants). By September 1961, seedlings grew well,
