摘要
通过对樟子松实生苗及其与彰武松的嫁接苗生长对照,研究了樟子松嫁接彰武松的可行性,表明樟子松嫁接彰武松成活率平均为77.3%,嫁接苗在嫁接后1a、2a高度生长分别高于樟子松实生苗36.0%和44.0%,在嫁接后9a,高度和地径生长分别高于樟子松82.0%和47.0%,以樟子松为砧木嫁接彰武松可以在北方推广。
Seeded plant of Pinus sylvestnis var. mongolica Litv. were compared with the grafted seed- ling with Pinus densiflora var. Zhangwuensis in terms of their growth. The result showed that the grafted seedlings would reach 77.3%, the height growth at 1 a and 2 a is 36.0% and 44.0% over the seedlings of Pinus sylvestnis var. mongolica Litv. After 9 years, the height growth and stem growth were 82.0% and 47.0% over, indicating the seedlings with Pinus sylvestnis var. mongolica Litv. as the stock is suitable for north China,
