摘要
以1 a生瑞典能源柳无性系为材料,进行不同嫁接时间、不同砧木、不同嫁接方法和整形可塑性试验。结果表明:嫁接成活率春季较秋季高15.1%;乡土树种旱柳和金丝柳均可做砧木,金丝柳的嫁接成活率较高,在6个无性系中,插皮接法成活率较旱柳高10.0%,带木质部芽接高6.5%;嫁接方法以改良插皮接最优,嫁接伤口愈合好,普通插皮接次之,带木质部芽接和劈接法成活率最差;柳树主枝适合于进行小于180°的弯曲造型;平茬具有复壮作用,首先促进了分枝,其次是增加了分枝基径和高的相对生长量,叶片数的增幅最小。
Different grafting time, rootstocks, grafting methods and shaping plasticity experiments were implemented with Sweden energy willow clones of one-year-old seedlings. The results showed that grafting in spring was better than in autumn. The average survival rates of all clones grafting in spring were 15.1% higher than in autumn. Local species, such as Salix matsudana and S. aureo-pendula were suitable to be used as rootstock. The survival rate of bark graft of 6 clones with S. aureo-pendula were 10% higher than S. matsudana. Equally, it was 6. 5% higher in xylem sap budding. The energy willow clones can well maintain their own characteristic just as cuttage seedling. Improved bark graft was the best method with well wound healing, bark graftage took the second place, xylem budding and cleft-grafting were the worst. The main branch of energy willow clones can be undergone a 180° curving shaping. Stumping had rejuvenation function, it firstly can promote branching, and secondly, increased the base diameter of branching and height. The increment of the number of leaves was the smallest. The research can be served as the basis for seedling cultivation of garden seedling tree of the energy willow clones and varieties resources conservation.
