| 摘要: |
| 以广西壮族自治区贺州市东潭林业科学研究所杉木（Cunninghamia lanceolata）无根组培苗为材料，进
行微扦插生根试验，初步建立杉木组培苗微扦插生根技术方法。结果表明：（1）以 50 mg/L IBA 25 mg/ L
NAA 做生根剂、黄心土做基质，生根周期缩短，生根率达 72%，为基质与生长调节剂的较优组合；（2）
在植物生长调节剂中浸泡 15 min 的吸收效果最好，生根率达 75%；（3）移栽后追施 10 mg/L NAA 的苗木
生根质量较优，生根率达 88%。 |

| Abstract: |
| The rooting of micro-cuttage experiment of Cunninghamia lanceolata was carried out by using
the rootless tissue culture seedling as the material from Dongtan Academy of Forest in Guangxi, and the method
of micro-cuttage rooting for rootless tissue culture seedling of C. lanceolata was preliminarily established. The
results were as follows: (1) The optimal combination of substrate and growth regulators was 50 mg/LIBA 25
mg/LNAA as rooting agent and subsoil of the yellow earth as substrate, the cycle of rooting was shortened and
the rooting rate was 72%; (2) The time of soaking in the plant growth regulator was better at 15 min, and the
rooting rate was 75%; (3) In the later management, the rooting quality of NAA seedling was better than that of 10
mg/L, and the rooting rate was 88%. |
