| 摘 要： | 对大田不同施肥条件下菊芋光合速率、蒸腾速率和水分利用率进行了测定，结果显示菊芋在低施肥条件下的光合速率和水分利用效率较高．进一步证明菊芋是耐旱耐瘠薄植物．这为菊芋人工大面积种植技术提供了依据。

| Abstract: | The photosynthetic rate, transpiration rate and water utilization rate of Jerusalem artichoke （Helianthus tuberosus Linn.） under different fertilization in the field were determined. The results indicated that the photosynthetic rate and water utilization rate of Jerusalem artichoke were high under low fertilization. This further proves that Jerusalem artichoke is a drought and barren tolerance plant, also provide technique intormation tor large artificially planting Jerusalem artichoke. |
