在田间条件下研究了免耕栽培对水稻叶片光合作用的影响。在浙江省嘉兴市、杭州市和萧山市进行了为期两年（2005年和2006年）的免耕和常规耕作试验。嘉兴地区免耕栽培的产量基本不变，杭州和萧山地区免耕栽培的产量略高于常规栽培。与常规栽培相比，免耕栽培抽穗前生物量积累较少，灌浆期物质生产能力较高。免耕处理的叶片净光合速率显著高于常规耕作处理。叶片的荧光参数（Fv/Fm）在两种栽培方式之间无明显差异。栽培管理对水稻叶片蒸腾速率（Tr）和SPAD值的影响因地点和年份而异。
A study was conducted to determine the influence of no-tillage cultivation on leaf photosynthesis of rice plants under field conditions. Experiments with the treatments, no-tillage and conventional tillage were carried out at three locations (Jiaxing, Hangzhou, and Xiaoshan, Zhejiang Province, China) for two years (2005 and 2006). Grain yield was constant in Jiaxing, but slightly higher in Hangzhou and Xiaoshan under no-tillage cultivation than that under conventional cultivation. In comparison with the conventional cultivation, no-tillage cultivation showed less biomass accumulation before heading and higher capacity of matter production during grain filling. A significantly higher leaf net photosynthetic rate was observed for the plants under no-tillage than for those under conventional tillage. The fluorescence parameter (Fv/Fm) in leaf did not show any difference between the two cultivations. The effect of cultivation management on transpiration rate (Tr) and SPAD value of rice leaf was dependent on the location and year.
