| 摘 要： | 以草炭土、珍珠岩、蛭石、椰糠、松林下土、山地红壤作为思茅松育苗的轻型基质原料，研究6种基质不同配比对思茅松幼苗生长特性的影响。结果表明:基质重量、幼苗保存率和苗高可有作为评价优良轻基质配方的重要指标；草炭土∶蛭石∶松林下土按4∶1∶5的比例配置成的基质育苗效果较好，思茅松幼苗保存率、苗高、地径、主根长和侧根数分别比对照高出9.46%、6.53 cm、0.12 cm、6.42 cm和13条，而单位基质重量则比对照轻233 g，该比例可以在思茅松容器培育优先考虑的轻基质配方，基质重量与幼苗保存率之间有显著负相关。

| Abstract: | Six kinds of light substrates, such as turfy soil, perlite, vermiculite, coconut tree branny, understorey soil of pine forest and mountain red soil were mixed with different proportions to culture the seedlings of Pinus kesiya var. langbianensis and to find out the influences of the substrates on the quality of the seedlings. Weight of substrate, seedling survival rate and seedling height were used as indices for the selection of optimal ratios. Satisfactory results were achieved for the substrate with a proportion of lime: vermiculite: pine forest soils=4∶1∶5, by which the seedling survival rate, height, ground diameter, main root length and number of lateral root were 9.46% , 6.53 cm, 0.12 cm, 6.42 cm and 13 higher than those of the control, and the matrix weight was 233 g lighter than the control. The proportion could be applied preferably for culturing container seedlings. Significant and negative correlation was observed between substrate weight and seedling preserving rate. |
