以RYL4、 RYL5、 RYL6三个品种油棕为研究材料，对各个器官(鲜叶、鲜茎、鲜根、鲜雄花、鲜小果、鲜熟果、鲜果穗、鲜果仁)中五大养分元素N、 P、 K、 Ca、 Mg的含量进行研究。结果表明院(1)各器官养分元素的高低顺序院鲜叶、鲜雄花、鲜熟果为N＞K＞Ca＞Mg＞P；鲜茎、鲜小果、鲜果穗为K＞N＞Ca＞Mg＞P；鲜根为K＞N＞Mg＞Ca＞P；鲜果仁为N＞K＞P＞Mg＞Ca。(2)不同器官总养分含量高低顺序院鲜小果＞鲜雄花＞鲜叶＞鲜果穗＞鲜果仁＞鲜根＞鲜茎＞鲜熟果。(3)不同品种油棕各器官养分含量高低顺序院鲜叶为RYL4＞RYL6＞RYL5；鲜茎、鲜雄花、鲜小果为RYL5＞RYL4＞RYL6；鲜根为RYL6＞RYL4＞RYL5；鲜熟果为RYL6＞RYL5＞RYL4；鲜果穗、鲜果仁为RYL5＞RYL6＞RYL4。
以RYL4、 RYL5、 RYL6三箇品種油棕為研究材料，對各箇器官(鮮葉、鮮莖、鮮根、鮮雄花、鮮小果、鮮熟果、鮮果穗、鮮果仁)中五大養分元素N、 P、 K、 Ca、 Mg的含量進行研究。結果錶明院(1)各器官養分元素的高低順序院鮮葉、鮮雄花、鮮熟果為N＞K＞Ca＞Mg＞P；鮮莖、鮮小果、鮮果穗為K＞N＞Ca＞Mg＞P；鮮根為K＞N＞Mg＞Ca＞P；鮮果仁為N＞K＞P＞Mg＞Ca。(2)不同器官總養分含量高低順序院鮮小果＞鮮雄花＞鮮葉＞鮮果穗＞鮮果仁＞鮮根＞鮮莖＞鮮熟果。(3)不同品種油棕各器官養分含量高低順序院鮮葉為RYL4＞RYL6＞RYL5；鮮莖、鮮雄花、鮮小果為RYL5＞RYL4＞RYL6；鮮根為RYL6＞RYL4＞RYL5；鮮熟果為RYL6＞RYL5＞RYL4；鮮果穗、鮮果仁為RYL5＞RYL6＞RYL4。

This experiment studied the content of five nutritive elements N, P, K , Ca and Mg in different organs (fresh leaf, stem, root, male flowers, young fruit, ripe fruit, fresh ear and kernel) of three oil palms varieties (RYL4 RYL5 and RYL6). The results showed that: (1) the order of nutrient elements content in fresh leaf, fresh male flowers and fresh ripe fruit were N > K > Ca > Mg > P; in Fresh stem, fresh small fruit and fruit ear were K> N> Ca > Mg > P;in fresh root was K> N> Mg > Ca > P;in fresh nut was N > K > P > Mg > Ca. (2) the order of total nutrient content in different organs was:fresh small fruit> fresh male flowers> fresh leaf>fresh ear >fresh nut> fresh root > fresh stem>fresh ripe fruit. (3) the order of nutrient content of each organ in different varieties was:in fresh leaf was RYL4 > RYL6 > RYL5; in fresh stem, fresh male flowers and fresh small fruit were RYL5 > RYL4> RYL6;in fresh root was RYL6 > RYL4 > RYL5;in fresh ripe fruit was RYL6 > RYL5 > RYL4;in fresh ear and fresh nut was RYL5> RYL6> RYL4.
