摘要
对集约管理和粗放管理2种模式在不同海拔条件下油茶幼林生长状况进行调查分析,探讨滇南高山峡谷区立体小气候对油茶幼树的生长影响程度.结果表明,在集约管理条件下,海拔1 500 m地段的油茶幼林,其平均地径、株高、春梢生长量分别比海拔1 600 m地段的增加了64%、28%、67%.集约管理与粗放管理相比,地径、株高、春梢生长量分别增加了37%、44%、128%.但海拔对粗放管理的幼林影响较小.建议在种植技术和管理措施设计时充分考虑因海拔变化而导致的小气候对油茶幼林生长的影响,更好地做到因地制宜,提高生产效益.
To study the effects of microclimate on the growth of young oil camellia in High Mountain and gorge area of south Yunnan, intensive and extensive management model were applied to the new plantation in different elevation. It shows the growth of young camellia was effected obviously by the change of elevation and management model. Under the intensive management trials, with the elevation decrease from 1600m to 1500m, the diameter at ground, height and spring tip of young oil camellia increased by 64% , 28% and 67% respectively, and increased by 37% , 44% and 128% respectively than that of extensive management trials. Therefore, it is suggested to pay more attention to plantation and management according to the change of elevation in High Mountain and gorge area in the south of Yunnan.
