山茶属6物种蒸腾速率的研究

STUDIES ON THE TRANSPIRATION RATIOS OF SIX OIL TEA SPECIES

本文对山茶属普通油茶、小果油茶、多齿红山茶、越南油茶、广宁红花油茶和博白大果茶等6个物种的蒸腾速率进行了测定,分析了其年变化、季节变化和日变化以及其与环境因子的相关关系,筛选出了影响蒸腾速率的主导因子,建立了经验公式,为合理拟订营林技术措施提供了依据。

The transpiration ratios of six species of oil tea trees, namely, Camelliaoleifera, C. meiocarpa. C. polyodomta, C. vietnamensis, C. semiserrata, C.gigantocarpa have been determined. Their annual, seasonal and daily changesand their correlations with the environmental factors have been analysed,and the leading factors which affect the transpiration ratio have been screenedout. The establishment of the empirical formula provides a reliable basis forthe preparation of rational silvicultural techniques.
