摘要
以钻天柳为研究对象,通过不同对比试验,观察其对钻天柳幼树成活率及生长的影响。结果表明:应用S2-0营养杯苗造林比应用S1-1床播苗造林效果好,成活率可达98%;在春季和雨季分别运用营养杯苗造林,其成活率均达到98%以上,而且对钻天柳幼树生长影响差异不大;钻天柳适宜在河流两岸的沙壤土上造林,其4龄幼树高生长和径生长比在壤土上造林分别提高94%和62%。
In this paper, the analysis on and Growth of sapling Chosenia arbutifolia were done through the different com- parative trials. The result of test showed that, the effect of use two years nutrition cup seedling afforestation was better than use one add one year＇s bed planting seedling afforestation, survival rate was 98%. The survival rate were all above 98% u- sing nutrition cup seedling afforestation in spring and rainy season, and the effect differences of sapling Chosenia arbutifolia growth wasn! obvious. The afforestation of Chosenia arbutifolia was fit on the silty loam than on the loam. The four years of sapling Chosenia arbutifolia＇s high growth and diameter growth on the silty loam were increased by 94% and 62% than on the loam.
