摘要
采用苗龄1-4年生无患子苗木进行了造林对比试验，并且在林龄7年时分别对无患子的保存率、地径、冠幅、霜冻受害情况进行了调查，结果表明：采用苗龄4年生无患子（造林后3年后调查）的平均保存率、平均地径最高，分别为97.3%，5.9cm；平均冠幅以苗龄3年生（造林后4年后调查）的无患子最大，为3.8m。霜冻受害率以苗龄4年生无患子最低，为2.9％。
Taking the soapberry seedling whose age is 1 to 4A to conduct the afforestation comparison experiment,the article studies the preserving rate, diameter, crown width and frost victimization of the soapherry seedling when the age of stand reaches 7 years. The results indicate that the average preserving rate and diameter reach the highest when adopting the seedling age of 4A （investigation after 3A of afforestation）, which is respectively 97.3% and 5.9 cm;in terms of the average crown,soapberry whose seedling age is 3A （investigation after 4A of afforestation） is the largest, which reaches 3.8m. The lowest frost victimization rate happens in soapberry whose seedling age is 4A,which is 2.9%.
