摘要
本研究以遂昌县低产油茶林为更新改造对象,通过不同间伐强度调节林分密度,并对伐后油茶林进行补植。结果表明,采用30%间伐强度进行低产油茶林改造,更新第2年单位产量已经超过间伐前,3年平均产量增加82.3%;不同间伐强度下补植,苗木前期生长差异不显著。此研究旨在为低产油茶林改造提供参考。
In this paper,a study was made on upgrading and improving the low-yield Camellia oleifera plantations in Suichang County.The stand density was adjusted by thinning at different intensities and complementary planting after-thinning.The results showed that the specific yield of the upgraded and improved low-yield plantation thinned at 30%intensity was higher than that before thinning in the second year and increased by 82.3%in the third year.There were no significant growth differences among complementary saplings in stands with different thinning intensities.The study is aimed to provide reference for improving low-yield C.oleifera plantations.
