摘　　要：造林前,对毛白杨苗木进行裸根晾晒试验。结果表明,主、侧根绝对含水率分别为120.2%～152.4%,149.8%～180.3%时,是造林成活的最佳含水率。在裸根晾晒条件下,苗木侧根失水最快,梢部失水缓慢,其顺序为:侧根>干基>主根>干中部>稍部。当裸根晾晒超过8d,主、侧根绝对含水率低于65%时,50%的苗木死亡,50%的苗干干枯。An experiment of sun baked naked root of Populus tomentosa stock was conducted before plantation. It showed that when absolute water content of central root was 120.2%～150.4% and that of side root 149.8%～180.3%,the platation showed best effect. In condition of sun baked naked root, the side root water-loss was the fastest, the top of the stem was the slowest. When naked root was baked over 8 days and root water content was below 65% ,half of the stock died out.
