摘    要:以"川麦44"为材料,单因素随机区组设计,研究3种前茬(大豆茬、玉米茬、红苕茬)对套作小麦花后物质积累、叶片光合特性及产量构成的影响。结果表明,前作为玉米和大豆时,开花时旗叶净光合速率高,叶片厚且叶色深;花后绿色叶面积大,持续时间长,叶绿素下降缓慢,叶片衰老延缓;玉米茬和大豆茬的小麦单茎干物质积累量大,成熟期干物重在穗中的分配比例大,表现为穗粒数多,千粒重大,单穗重高,最终产量豆茬和玉米茬小麦显著高于苕茬小麦。

关 键 词:小麦  前作  光合特性  物质积累  产量

Abstract:In this study,single radom-plot design was conducted to study the effects of different preceding crop(soybean stubble,maize stubble,sweet potato stubble) on the accumulation of dry matter,flag leaf photosynthetic characters and yield of wheat c.v.Chuan-mai 44 after flowering.The results showed that: when the stubble was maize and soybean,there was a higher net photosynthesis rate and chlorophyll content in flag leaf,and the flag leaves were thicker and wider,the green leaf area declined slowly after floweri...
Keywords:wheat  preceding crop  photosynthetic character  accumulation of dry matter  yield
