为探明水氮调控对沟灌棉花群体生长发育的影响机制,通过设置3种沟灌方式、3个灌水量和施氮量水平进行大田沟灌棉花试验研究,并利用高斯单峰分布模型模拟棉花群体生理指标变化趋势。试验结果表明:模型模拟精度相对较高。施氮处理下:与常规沟灌相比,交替隔沟灌低氮处理叶片光和势峰值下降39.3%,中氮处理各指标无显著差异,高氮处理下叶片光和势峰值提高17.26%,群体净同化率峰值下降21.69%;固定隔沟灌方式不同施氮处理各指标峰值下降35.1%～44.0%。灌水处理下:与常规沟灌相比交替隔沟灌低水分处理叶片光和势峰值下降23.94%,中等水分处理下叶片光和势提高13.63%,叶面积指数下降14.2%,高水分处理下各指标参数无显著差异;固定隔沟灌方式不同灌水处理各群体指标下降20.7%～47.22%。与常规沟灌棉花生物量和产量相比,交替隔沟灌各水氮处理地上干物质重和产量无显著差异,固定隔沟灌地上干物质重下降9.8%～19.3%,产量下降7.6%～8.9%。因此,交替隔沟灌的根区水、氮调控对棉花群体性能影响较显著,能够有效调控棉花群体生长发育,对于棉花水肥管理具有重要的应用价值。

＜正＞Evapotranspiration is the process of externally dissipating the water moisture in plants and soil in the form of gas state. This paper summarized the primary methods home and abroad in deducing the evapotranspiration in woodlands. For the primary methods, they were discussed in the perspectives of principle, suitability, and economy of relevant equipment as well as accuracy of estimation algorithms. In the end of the paper, brief comments were given on the research pathway of evapotranspiration in woodlands.
