| 摘要: |
| 对2～5年生马尾松实生苗、扦插苗2种苗木进行造林对比试验，试验结果显示，这2种苗木造林的保存率都超过95%。扦插苗和实生苗2年生时5个测量性状（树高、胸径、冠幅、活枝轮盘数、侧枝总数）均差异不显著；3年生时树高、胸径差异显著，其它不显著；4年生时5个性状差异均显著。即从3年生开始扦插苗早期生长量才显著高于实生苗。说明扦插林早期较实生林速生。在种子短缺的情况下，利用优良的无性系繁殖苗木，是十分有效的。 |

| Abstract: |
| lives the masson pine seedling, the cuttage seedling 2 kind of nursery stock to 2~5years to carry on the afforestation comparative trial, the test result demonstrated that these 2 kind of nursery stock afforestation's survival rate surpasses 96%. The cuttage seedling and the seedling 2 years lives when 5 survey characters (tree is high, tree diameter at chest height, crown, lives wheel disk number, lateral branch total) the even difference not to be remarkable; 3 years live when the tree is high, the tree diameter at chest height difference is remarkable, other are not remarkable; 4 years live when 5 character differences are remarkable. Namely lives from 3 years starts the cuttage seedling early growth quantity to be only then remarkable is higher than the seedling. Explains the cuttage forest early time grown directly from seed forest fast-growing. In the seed short situation, uses the fine clone reproduction nursery stock, is very effective. |
