摘要
灌木柳是国外用于生物能源林培育的主要品种之一,收集了20多种生物量较高或适应性较强的灌木柳树种质资源,根据适应性和生长性状互补的原则选择杂交组合,开展了人工杂交330个组合,通过多年连续的测定,筛选了一批子代无性系用于区域性试验,优选了3个高产无性系,分别是2345、52-2和20,他们的生长量均超过目前生产品种的30%以上。
Shrub willow is the mainly variety used for cultivating bioenergy stands. For selecting high bio- mass willow varieties which could he applicable for short rotation coppice willow in China, more than 20 species of shrub willow germplasm with high biomass or strong adaptability were collected. According to its characteristics of growing and adaptability, about 330 crosses were taken, a batch of its progenies were selected for regional experiment after seedling-test for consecutive years. We have got three clones with high biomass through the experiment, and their increments are all more over 30 % than those of the current cultivars＇.
