| 摘 要： | 在福建南平峡阳国有林场,采用固定标准地法研究杉木造林后1 a补植的杉木补植苗的生长过程。结果表明:杉木补植苗(补植后7 a,树龄为8 a)与造林苗的生长量存在较大差异,其平均胸径、平均树高、平均高径比和平均单株材积分别是造林苗(造林后8 a,树龄为9 a)的71.83%、81.20%、113.01%和43.52%,分别是相同树龄(造林后7 a)造林苗的78.40%、89.16%、113.78%和56.10%。

| Abstract: | Growth course of the Cunninghamia lanceolata reinforcement planted seedlings 1 year after the plantation was studied in Xiayang State-Owned Forest Farm,Nanping,Fujian,China.The results showed that the great discrepancy was found between the growth of 8-year-old reinforcement planted seedlings 7 years after the reinforcement planted seedling and plantation seedling.Mean DBH,mean height,mean ratio of height to DBH and mean single tree stem volume of the reinforcement planted seedlings were 71.83%,81.20%,113.01% and 43.52%,respectively,which were 78.40%,89.16%,113.78% and 56.10%,respectively,of the seedlings(7 years after plantation) with the same age. |
