摘　　要：姜黄植株各器官中氮、磷、钾的含量分布以幼嫩器官较高，全株以苗期含量最高，三要素含量顺序为钾＞氮＞磷。整个生育期间，氮、磷、钾的吸收主要发生在生育中期和后期。氮、磷、钾的转运主要是从叶和叶柄向子姜和母姜转运，其中磷的转运率最高。It has been found out that the percentages of nitrogen (N). Phosphorus (P) and potassium (K) inturmeric plant (Curcuma longa) are higher in young organs. Varying with the growth stages . the nutrient contents ofthe plant,whose aniount urder is K> N>P are the highest in the seedling stage. Nutricnt absorption occurs mainly inthe young turmeric forming stage and enriching stage. Nutrient translocation takes place mainly from leaves and leafstalks to young and old turmeric,the rate of P being the highest.
