摘要：采用田间调查与实验室分析相结合，探讨海南地区不同产量水平、不同生长年限、正常结果与黄化核榔叶片氮、磷、钾含变化规律。结果表明，槟榔叶片氮、磷、钾比例约为1:0.081:0.356。高产组槟榔叶片平均鼠含量比中高产组和中产组的分别高10.45%和21.73%；面比低产组槟榔叶片的高了36.86%。正常结果树（低产组槟)叶片平均氮含量比黄化组（轻)和黄化组（重)的分别高10.15%和19.49%；黄化组（轻)槟榔叶片平均氮含量比黄化组（重)的高11.61%。高产组槟榔叶片平均硝含量比中高产组和中产组的分别高10.71%和13.64%；面比低产组槟榔叶片的高17.02%。正常结果槟榔（低产组)叶片平均磷含量比黄化组（轻）和黄化组（重）的分别高10.87%和18.48%；黄化组(轻)槟榔叶片平均磷含量比黄化组（重)的高8.5%。高产组槟榔叶片平均钾含量比中高产组和中产组的分别高17.24%和25.00%；面比低产组槟榔叶片的高31.96%。正常结果槟榔（低产组）叶片平均钾含量比黄化组（轻）和黄化组（重）的分别高15.15%和19.42%：黄化组（轻)槟榔叶片平均钾含量比黄化组（重）的高5.03%。不同生长年限槟榔叶片氮、磷、钾含龄有所差异，随着树龄增加，高产组槟榔叶片氮、磷、钾含量比较低产组的高。槟榔叶片氮含量最高，钾次之，磷最低。氮磷钾含量对槟榔产其提高有很大影响，槟榔黄化病可能引起叶片中N、P、K含量降低。关键词：槟榔；氮；磷；钾；产量水平；生长年限；黄化病

Abstract: Aimed to analyze the content of N, P and K of betel leaves, the normal leave the ones with yellow leaf disease were collected from fruit-bearing arecanut (Areca catechu L. ) with different production levels, at different growth years in Hainan. The results showed the ratio of N : P : K was 1:0. 081:0.356 in arecanut leaves. The av-erage N contents in high-yield group( HYG) were 10. 45% , 21. 73% and 36. 86% higher than those in middle high-yield (MHYG), middle-yield group(MYC), and low-yield group (LYG), respectively. The average N con-tents in normal arecanut leaves (low-yield group betel) were 10. 15% and 19. 49% higher than those in light yellow leaf disease group (LYLDG) and in severe yellow leaf disease group (SYLDC). The average P contents in HYG were 10. 71% and 13. 64% higher than those in MHYG and MYG, respectively, and with 17. 02% higher than those of LYG. The average P contents in nommal arecanut leaves (LYG) were 10.87% and 18.48% higher 收稿日期：2010-01-20
