摘　　要：对塔河地区钻天柳营养钵幼苗生长情况进行分析的结果表明,播种20天后苗高、地径和根长呈阶段性生长,30~40天苗高和根长的生长速度最快,9个月苗高生长呈显著差异,地径和根长生长差异不显著,个体间苗高差异较大,造林前应做进一步选优。The analysis of the growth of seedlings in the nutrient bowl of Chosenia arbutifolia in the Tahe area shows that the seedling height,ground diameter and root length grow in stages after sowing for 20 days,and the seedling height and root length grow fastest in 30-40 days At 9 months,there was a significant difference in seedling height growth,but there was no significant difference in ground diameter and root length growth.There was a large difference in seedling height between samples.Further optimization should be done before planting.
