福建柏红锥混交造林生长效果分析

Analysis on Growth Effect of Mixed Afforestation With Red Cone in Fujian

针对杉木低产林进行改造,营造福建柏红锥混交林、纯林,经过12年的经营管理,对不同的林木生长量进行了效果调查和分析。结果显示:福建柏红锥混交林的林木生长量优于纯林林木生长量,分别平均树高高度大于15.56%和3.33%,胸径粗17.85%和7.92%,树冠大11.72%和4.81%,枝下高高于35.64%和14.1%,单株体积大57.69%和20.59%,蓄积量积多45.29%、12 61%。混交林的涵养水源功能,土壤养分也高于纯林。

China fir low-yield forest was reconstructed to create mixed forest and pure forest of Bohong cone in fujian province. After 12 years of operation and management, different forest growth was investigated. The results showed that the growth rate of forest was higher than that of pure forest; the average height of tree height was higher than 15.56% and 3.33%; the diameter of chest was larger than 17.85% and 7.92%; the canopy height was larger than 11.72% and 4.81%; the subbranch height was higher than 35.64% and 14.1%; the volume of individual plant was larger than 57.69% and 20.59% and the accumulation volume was higher than 45.29% and 1261%, respectively. The conserving water function of mixed forest was higher than that of pure forest.
