| 摘 要： | 以穿龙薯蓣不同生长时期的根、茎、叶、果(花)为试材，测定了氮、磷、钾含量并分析其变化规律。结果表明：根茎中氮、磷、钾含量在营养生长期、根茎旺盛生长期和枯萎期有很大波动，且营养期高于根茎旺盛生长期和枯萎期；植株地上部分茎的氮、磷、钾含量均低于叶和果(花)，果(花)除花期外氮含量低于叶片，钾含量高于茎和叶片。 |
| 关 键 词： | 穿龙薯蓣 规律研究 含量变化 磷 养分 营养生长期 钾含量 生长时期 变化规律 地上部分 根茎 营养期 氮含量 枯萎 叶片 植株 花期 |

| Abstract: | The content of N, P and K was measured in order to know the varying laws in root, stem, leaf and seed(flower) of Dioscorea nipponica in different growth periods. The results showed that the content of N, P and K in rhizome fluctuated greatly in vegetative growth period, fast growth period and fade period, and it was higher in the vegetative period than that in other two periods; The content of N, P and K in stem was lower than that in leaf and fruit(flower), except in blooming period, the content of N in fruit(flower)was lower than that in leaf and the content of K in fruit(flower) was higher than that in stem and leaf. |
| Keywords: | Dioscorea nipponica nutrition content N P K |
