| 摘 要： | 采用控制灌溉技术,通过不同的水肥配合比,研究水肥耦合对水稻的叶面积指数的影响,并进一步探究叶面积指数与腾发量、产量之间的相关关系。试验采用D-最优饱和设计方法设计水肥配合比,试验小区根据随机区组原理进行布置。通过试验得出以下结论：水分和氮肥对叶面积指数具有主要的促进作用,钾肥和磷肥次之;叶面积指数与腾发量、水分利用率呈正相关;叶面积指数的增加可以提高产量。

| Abstract: | The effects of water-fertilizer coupling on rice LAI was studied under the condition of controlling irrigation,besides exploring the correlations of LAI and the transpiration rate,LAI and yield.The mix proportion of water and fertilizer was determined by the Saturation D-best design method,and the experimental plot was arranged randomly.The results showed that：water and nitrogen promote LAI significantly,potassium and phosphorus take the second role;LAI and the transpiration rate,LAI and water productivity are positive correlation;the rice yield can be improved by increasing the LAI else. |
