摘　　要：目的研究温郁金对N、P、K的吸收和分配规律。方法定点采样,样品在50℃烘箱中烘干,分别测定叶、根茎、须根和块根中氮、磷、钾的百分含量。结果温郁金在整个生长过程中对氮肥和钾肥的需求量较大,其中钾肥需求量约为氮肥2倍,对磷肥的需求量则较少。结论通过对氮磷钾吸收量和分配规律的分析,对温郁金生长过程中肥料施用的定量化、标准化提供了理论依据。Objective To study on the rule of absorption and distribution of N, P, K in growing stage of Common Turmeric. Methods Samples of CommonTurmeric were collected for fixed points and was kept in an oven drying at 50℃, the contents of N,P,K were quantitative determined respectively from leaf, rhizome, fibrous root and root tuber of Common Turmeric. Results of Common TurmericFertilizer Fertilizer, while P Fertilizer had little demand. Conclusion This work provided theoretical basis for quatitative and standardization of fertilizer application in growing stage of Common Turmeric .
