摘要： 探讨不同产量水平、正常结果与黄化病槟榔叶片Na+与Cl-含量变化及不同生长年限槟榔叶片Na+与Cl-含量变化规律。以海南不同产量水平中不同生长年限正常结果与黄化槟榔叶片为试验材料，分析不同产量水平、正常结果与黄化槟榔叶片Na+、Cl-含量，以及不同生长年限槟榔叶片Na+、Cl-含量变化情况。结果表明：槟榔叶片含有较高Na离子。Na+平均含量约1.9%。槟榔叶片Na+随着产量水平无直线变化趋势。正常结果与黄化槟榔叶片Na+含量差异也不明显。Cl-含量在槟榔叶片较低。槟榔叶片Cl-含量随着槟榔产量下降有所下降，中产组和低产组的比高产组的分别下降了约30%和45%。黄化槟榔叶片Cl-含量比高产和低产组的低约60%和28%。槟榔叶片Na+含量随着生长年限呈下降趋势，而槟榔叶片Cl-含量随着生长年限无明显直线变化规律。结论：不同产量槟榔间Na+含量差异不明显。高产量的槟榔叶片Cl-含量比较高，黄化槟榔叶片Cl-含量明显低于正常槟榔的。Na+随着槟榔生长年限增加有所下降但Cl-无明显直线变化趋势。

Abstract: The objective of study was to analyze the Na- and Cl- dynamic of the arecanut leaves from different yield levels, different growth years and the ones with yellow leaf disease. The leaves were collected from normal fruit-bearing arecanut in different production levels and different growth years and those of yellow leaf disease for the experimental materials. The results showed that the Na + content was high in leaves. The average Na + content was 1.9%. The Na+ content of the arecanut leaves had not a significant change, and which didn’t show a line trend with arecanut yield varying. The differences in Na + content between normal arecanut leaves and ones with yellow leaf disease was not significant. The Cl- content of arecanut leaves decreased with yield declining, The Cl- content of arecanut leaves in the middle- and low-yield groups decreased by about 30% and 45% than that in high-yield group, respectively. The Cl- content of yellow leaf disease was 60% lower than that of high-yield group, and was 28% lower than that of low-yield group. Na+ content of Arecanut leaves decreased with the growth time. However, the Cl- content of arecanut leaves had no significant change with growth time increasing. There was no significant difference between different grades in productions, Na+ declined along with arecanut growing time increasing. Arecanut leaves with the high yield have relatively high Cl-, and Cl- content of arecanut with yellow leaf disease was significantly lower than that of the normal arecanut, Cl- content has not an obvious linear trend with the growing time.
