摘要： 分析、研究了水葫芦植株不同生长时期、不同部位的全氮和全磷含量，并与常见的经济作物进行比较。结果表明：供试水葫芦植株各部位的水分含量较皆高于90%；不同生长部位和生长阶段的氮与磷素营养含量不同，幼叶对氮和磷素的需求皆高于老叶；与主要作物相比，水葫芦对氮与磷素营养的吸收能力较强。

Abstract: The content of nitrogen and phosphorus in the different parts of water hyacinth was tested, and some other economic crops were compared with it in the paper. The results were as follows. The water content of every part tissue in water hyacinth were all higher than 90%, and the content of nitrogen and phosphorus were different in according to parts and growing stages, and the content of nitrogen and phosphorus in younger leaves were higher than that of the old. It was also found that the nitrogen and phosphorus absorption capacity of water hyacinth was higher than that of some economic crops in generally.
