| 摘 要： | 在全光自控喷雾条件下，对不同年龄的红皮云杉硬枝和嫩枝进行了扦插繁殖。试验结果表明：在扦插繁殖中存在着明显的年龄效应和位置效应，来自于小年龄母株，树冠中下部的插穗具有较高的生根能力；用硝酸盐稀土１００μｇ／ｇ浸泡插穗３ｈ可使７年生嫩枝插穗生根率达８８．７２％，高出对照３１．９％；扦插苗移栽的最佳时间为８月中旬，扦插苗不定根数目是影响移栽成活率的重要因素。

| Abstract: | With the outside automatic mist system, the softwood and hardwood cutting propagation of Picea koraiensis in different ages was conducted. The cuttings of Picea koraiensis presents significant effects of age and position. The cuttings from younger mother trees and the lower position of crown have higher rooting ability. Rooting rate of the cuttings reached 88.72%, or 31.9% higher than control, when based ends of softwood of 7 years old cuttings were soaked 3 h in aqueous solution of 100 mg/g rare-earth chemical compounds. The optimal transplanting time for the seedlings is in the middle of August and the number of roots is an important factor that affects survival rate of cuttings. |
