【摘要】 84K毛白杨较难生根 ,硬枝插条育苗 1年只能繁育 1批苗木 ,而且需要的种条多。为了提高苗木的繁育速度和产量 ,适应当前造林绿化的需要 ,在弥雾条件下进行嫩枝插条育苗获得了成功 ,并生产了大量苗木 ,插条生根平均成活率达 91 3% ,移植平均成活率达 87 5 % ,平均保存率达 86 6 %。每 15～ 2 0天即可繁育 1批苗木 ,1年可以繁育 6～ 7批苗木。并总结出快速繁育 84K毛白杨的嫩枝插条育苗技术。更多还原

【Abstract】 The breed 84K of aspen is difficult rooting. It can breed only one batch of nursery stocks per year by stem cutting which need many stem cuttings. We get success in twig cuttage in water fog. This way fits to current afforestation need, which can produce more nursery stocks. The rooting average ratio gets to 91.3%, the surviving average ratio of transplant 87.5%, and the conservation average ratio 86.6%. We can get a batch in 15～20 days, and get 6～7 batches per year. In this article, the technology of fast breeding with twig cuttage is summed up.更多还原
