摘要
以P-15A杨、I-214杨和沙兰杨为材料进行试验研究。通过对其生物产量的调查、材性指标的测定和经济效益的计算资料进行分析研究,我们认为所研究地区进行杨树短轮伐期栽培以生产造纸原料是适宜的。选择速生杨树品种、确定合理的造林密度和轮伐年限是提高其生物产量、保证用材质量和良好效益的根本措施。
By surveying the biomass, determining the wood property and examining the economic benefits of plantations of poplar hgbrids P-15A, 1-24 and Sacrau, it was found suitable that short-rotation culture of poplats is used to produce pulpwood in the region where we made the investigation. selecting fastgrowing hybrids, adopting rational spacing and rotation age are the basic measures to increase biomass and guarantee both wood quality and good economic benefits.
