摘要
沙柳是防沙固沙、水土保持的优良灌木树种,也是重要的工业用材树种。自1996年~2000年,历时5a,对4个种源区92个优树进行田间试验,通过生物学特性,形态特征和经济性状的观测,及方差、相关、通径等多元统计分析;遗传多态性的筛选,选择了生长快、抗性强、生物量大、高产优质的Ⅴ-Ⅰ、ⅩⅣ-13、Ⅲ-01、ⅩⅣ-08、达采等7个优良无性系,为西部生态环境建设提供理论依据和物质基础。
Salix psammophila is a kind of good shrub, which can be used to resist wind, preserve natural environment and climate. It is also an important industrial material. From 1996 to 2000, during these 5 years,field experiment was done on 92 good trees of 4 seed source areas. The biological character, morphological character and economic character were observed. By using the method of variance analysis, relevance analysis and sifting the genetic diversification, 7 clones such as Ⅴ-Ⅰ、ⅩⅣ-13、Ⅲ-01、ⅩⅣ-08, Dacai were chosen as good clones. These clones grow fast,have strong hardiness,large biotic quantity,high production and good quality. The result provides theoretic and substance basis for ecology and environmental construction of the west.
