| 配置５个轻基质配方，用黄心土作为对照，采用３个不同规格的育苗容器，开展樟树
（Cinnamomum camphora）轻基质配方筛选和容器规格育苗技术研究。试验结果表明：苗木移栽 5 个月后，
苗木保存率在 96.0%~99.7% 之间。叶绿素 SPAD 值以配方 3 号（泥碳土 : 珍珠岩 : 松树皮 = 6:3:1）最好，
配方 1 号（泥碳土 : 珍珠岩 : 椰丝 =6:3:1）次之。苗木移栽 10 个月后，苗高生长最好的基质是配方 3 号，
比对照好；地径生长最好的基质也是配方 3 号 , 但比对照差；地上枝叶鲜重生长最好的基质是配方 3 号，
比对照略好；地下根系鲜重生长最好的基质是配方 1 号，配方 3 号次之，比对照好。综合苗高、地径及
地上枝叶鲜重和地下根系鲜重 4 个生长指标，５种基质配方中配方３号表现最好。３种不同规格育苗容
器中，12 孔的育苗容器培育的苗木苗高、地径、枝叶鲜重、根系鲜重均优于 15 孔和 28 孔的。因此利用
泡沫育苗架培育樟树１年生轻基质苗木宜采用泥碳土添加珍珠岩、松树皮作为育苗基质，选用 12 孔育苗
架作为育苗容器。 |

| Abstract: |
| Five light matrix formulations were allocated and yellow soil was used as check. Three seedling?raising frames with different specifications were used to study the light matrix formulation and container-size for
seedling-raising technology of camphor. The results showed that five months after transplanting, the preservation
rate of seedlings ranged from 96.0%-99.7%. matrix No.3（peat soil: perlite: pine bark=6:3:1）of chlorophyll
SPAD value was the best, matrix No.1 was the second, matrix No.2 was the worst, and the CK was the highest.
Ten months after transplanting, the best matrix for seedling height growth was No.3, which was better than the
CK, and the best matrix for ground diameter growth was No.3, but worse than the CK. The best growth of fresh weight of branch and leaves above ground was matrix No.3, which was slightly better than the CK. The best
growth of fresh weight of underground roots was matrix No.1, and matrix No.3 was the second, better than the
CK, Four growth indices of comprehensive seedling height, ground diameter, fresh weight of aboveground branch
and leaves and fresh weight of underground roots, among the five matrix formulations, matrix No.3 performed
the best. In three specifications of containers, the seedling height, ground diameter, branch and leaf fresh weight
and root fresh weight of 12-hole container were better than 15 and 28 holes. Therefore, peat soil with perlite, pine
bark as seedling matrix and 12-hole seedling shelves as seedling container are suitable for cultivation of 1-year-old camphor seedlings in light matrix. |
