| 摘 要： | 对比研究幼龄胶园间种香蕉后，橡胶与香蕉的光合及水分生理生态特性。试验结果表明：(1) 间种香蕉的橡胶树幼林净光合速率和蒸腾速率均高于无间种(对照)的橡胶树幼林，水分利用效率间作香蕉的胶树低于无间种的对(照胶)胶树；(2) 橡胶树下间种的香蕉净光合速率与对照香蕉间无明显差异，蒸腾速率以普通对照的香蕉略大，水分利用效率是间作的香蕉略大。幼林胶园间种香蕉，能充分利用林下资源，生态效应良好，值得发展。

| Abstract: | Young rubber trees were intercropped with banana, and the young rubber trees and banana were compared in terms of photosynthesis and water physio-ecology. The results show that rubber trees intercropped with banana had a higher net photosynthesis rate and transpiration rate but lower water utilization efficiency (WUE) than those without intercropping, and that the intercrop banana had similar net photosynthesis rate to and a slightly lower transpiration rate but a slightly higher WUE than the control banana. Intercropping of banana in young rubber plantations can cash in on the resources under the plantations, which has good ecological effects. This intercropping pattern deserves development. |
