柳树不同密度、插条粗度育苗对地径生长的影响大于苗高;无性系和密度处理苗木高径比差异极显著;苏柳无性系大田育苗高径比平均值在140～170间。从方便生产出发建议以地径一个指标作为柳树无性系苗木的质量标准。
The effects of different density and cuttings of seedlings on diameter growth were greater than that of seedling height. The height-diameter ratio of seedlings of clonal and density treatments was significantly different. From the point of view of the convenience of production, it is suggested that the quality standard of the willow clones seedlings be one index of the diameter.
