【摘要】 本文分别收集了不同产量水平、不同生长年限下健康结实槟榔和黄叶病槟榔的叶子,研究海南健康和黄叶病槟榔叶中氮、磷、钾在不同产量、不同生长年限下的动态变化水平。结果显示,氮、磷、钾的比例大约是1:0.081:0.356,高产组中平均氮含量高于中高产组10.45%,高于中产组21.73%,高于低产组36.86%。健康结实槟榔(低产组)中平均氮含量高于轻微黄叶病组10.15%,高于重度黄叶病组19.49%。健康结实槟榔(低产组)中平均磷含量高于轻微黄叶病组10.87%,高于重度黄叶病组18.48%。轻微黄叶病组中平均磷含量高于重度黄叶病组8.5%。高产组中平均钾含量高于中高产组17.24%,高于中产组25.00%,高于低产组31.96%。健康结实槟榔(低产组)中平均钾含量高于轻微黄叶病组15.15%,高于重度黄叶病组19.42%。轻微黄叶病组中平均钾含量高于重度黄叶病组5.03%。不同生长年限下氮磷钾的含量也有所不同。随着树龄的增长,高产组槟榔中氮磷钾含量高于低产组。氮含量最高,钾含量次之,磷含量最低。氮磷钾的含量对槟榔产量具有很大影响。生长过程中黄叶病会引起槟榔叶中氮磷钾含量的降低。

【Abstract】 The arecanut(Areca catechu L.) 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 objective of study was to analyze the content dynamic of N,P,K by the normal arecanut leaves of Hainan in different yield level and different growth years and by the ones with yellow leaf disease.The results showed that proportion of N,P and K of Arecanut was about 1:0.081: 0.356,average N content of Arecanut in high-yield group was 10.45%and 21.73%higher than those in high-middle yield group and middle-yield group respectively,and 36.86%higher than that in low-yield group,average N content of normal fruit-bearing tree(Arecanut in low-yield group) was 10.15%and 19.49%higher than those of gentle yellow leaf disease group and severe yellow leaf disease group. Average P content of normal fruit-bearing Arecanut(low-yield group) was 10.87%and 18.48%higher than those of gentle yellow leaf disease group and severe yellow leaf disease group,average P content of Arecanut in gentle yellow leaf disease group was 8.5%higher than that of severe yellow leaf disease group. Average K content of Arecanut in high-yield group was 17.24%and 25.00%higher than those in high-middle yield group and middle-yield group respectively,31.96%higher than that in low-yield group, average K content of normal fruit-bearing Arecanut(low-yield group) was 15.15%and 19.42%higher than those of gentle yellow leaf disease group and severe yellow leaf disease group,average K content of Arecanut in gentle yellow leaf disease group was 5.03%higher than that of yellow leaf disease group.N,P and K content of Arecanut in different growth years are somewhat different.With the increase of plant age, N,P and K content of Arecanut in high-yield group was higher than that of low-yield group.N content of Arecanut was the highest,followed by K,P was the lowest,N,P and K content has a great influence on yield of Arecanut,moreover,yellow leaf disease of Arecanut may cause the decrease of N,P and K content in leaf,during the Arecanut growth.
