摘要
利用不同接穗和砧木进行红松针叶束嫁接试验的结果表明:选用樟子松、赤松为砧木进行嫁接,成活率略低于红松同砧嫁接,萌芽率和成苗率显著高于同砧嫁接。当年生针叶嫁接效果最好,不同无性系对成活率影响显著。采穗宜选用树龄60年以下的母树,在树冠中、上部采穗,可以获得较高的萌芽率和成苗率。
The results of grafting experiments of Pinus kordiensis needle fascicle with different scions and rootstocks showed that the grafting rate of Pinus sylvestris and Pinus densiflora were used as the rootstock.The survival rate was slightly lower than that of the red pine and the anvil.The germination rate and seedling rate were significantly higher than that of the same anvil.The best coniferous grafting effect in the same year,Different clones had significant effects on the survival rate.For the ears,the mother trees with the age of 60 years or less should be used.In the canopy and the upper part of the canopy,higher germination rate and seedling rate can be obtained.
