| 摘 要： | 通过采用留植、移植、剪根移植3种不同方法培育杨大苗的试验,结果表明:3种方法培育的杨大苗质量有明显区别。留植苗在苗高、地径上有优势,但根系不好,侧根数少,主侧根过粗,起苗时易造成机械损伤,造林不易成活;而移植苗较留植苗质量有所改善,侧根数增多,起苗时机械损伤较少,造林易成活;最好的是剪根移植苗,克服了以上2种方法所有弊病,苗木质量优良,造林成活率高。

| Abstract: | In this paper,were used 3 methods of stubble,transplanting and transplanting after root prunning for culture of great seedlings of poplar.Stubble seedlings were superior in height and ground diameter to the others, but lateral root numbers were less and principal and lateral roots were thick,so were liable to mechanic injury in removing seedlings.The lateral root numbers of seedlings by transplanting were more, and mechanic injury was less.The best seedlings were that obtained by transplanting after root prunning.They overcome the above two disadvantages and have higher planting survival rate. |
