【摘要】 试验研究了常规栽培(CK)、地膜覆盖、垄沟栽培和垄播覆膜等4种不同栽培模式以及不同氮素水平对冬小麦小偃22旗叶生理特性及产量的影响。结果表明,施氮能够显著增加小麦各生育期叶片含氮量,能够明显增加产量；不同栽培模式下小麦旗叶生理特性变化基本一致,地膜覆盖、垄播覆膜和垄沟栽培均能显著增加旗叶含氮量,增加产量,以地膜覆盖和垄播覆膜尤为显著。因此,地膜覆盖和垄播覆膜栽培模式是本地区小麦优质高产高效栽培模武之一。更多还原

【Abstract】 A experiment was carried out to study the effects of four planting modes and different nitrogen on physiological characters and yield of the winter wheat Xiaoyan 22’s flag leaf.The results showed that nitrogen can increase the nitrogen content of the leaf and the grain yield,the physiological characters of the flag leaf var- ied in the same manners in the different planting modes,plastic sheet-mulching,Plastic sheet-mulching on ridge and ridge-furrow tillage also can increase the nitrogen content of the flag leaf and the grain yield.Plastic sheet- mulching and plastic sheet-mulching on ridge had a remarkable impact.So,plastic sheet-mulching and plastic sheet-mulching on ridge should be the better planting modes for advanced quality,high yield and high efficient in Northwest district.更多还原
