| 摘 要： | 利用20 a生小叶杨伐根和1 a生小钻杨根桩嫁接毛白杨,进行嫁接繁殖技术研究。结果表明,伐根嫁接毛白杨的成活率是根桩嫁接成活率的231.2%;3 a生的伐根嫁接植株平均高生长量为8.2 m,是苗圃地根桩嫁接法的200.0%;平均胸径生长量为11.4 cm,是苗圃地根桩嫁接法的175.4%,两者差异极显著。该方法成本低,在低产林改造、农田防护林更新、城镇和村屯绿化、水土保持林及护路林更新改造等方面具有广泛的推广价值。

| Abstract: | Grafting techniques of Populus tomentosa was conducted with stumps of 20-yr-old Poplus simonii and 1-yr-old Populus Xiaozhuanica.The results showed that survival rate of the former was 231.2% that of the latter;Average high growth of 3-yr-old plants grafted by stump was 8.2 m,that of 200% to stump grafting in the nursery;The average growth of diameter at breast height was 11.4 cm,that of 175.4% to stump grafting in the nursery,the difference between the two is extremely significant.Due to low-cost,this method has a wide promotion value on transformation of low-yield forest,rural and urban greening,regeneration of farmland protection forest,of soil and water conservation forest and road conservation forest. |
