| 摘 要： | 为比较不同林地类型和郁闭度对香榧幼苗栽培的影响,从2006～2009年连续四年记录在松阳县52块标准地香榧幼苗的成活率和新梢生长量,因素分析法结果表明:郁闭度、林地类型、郁闭度和林地交互作用对成活率均有极显著性影响,郁闭度对新梢生长量有显著影响。在郁闭度为0.4的板栗林、针阔混交林和杉木林种植香榧幼苗,其成活率均达到96%以上,新梢生长量达到21.5cm以上。 |

| Abstract: | To compare the effects on the regeneration of Torreya grandis at the different forest types and canopy density.The survival rate and shoot growth capacity were recorded in the 52 standard of Songyang downtown from 2006 to 2009.Factorial analysis showed that the survival rate was a highly significant differences between forest types,canopy density and their interaction,and the shoot growth capacity was only significant differences with canopy density.The survival rate and shoot growth capacity of Torreya grandis reached above 96% and 21.5 cm when they were planted under mixed coniferous forestry and fir forestry which canopy density was 0.4. |
