摘  要:
[目的]研究渍害对小麦生长的影响,探讨补救措施。[方法]采取渍害发生期(W)、恢复补救措施(R)2因子裂区设计,分析渍害发生期对小麦产量和产量构成的影响,研究不同补救措施的恢复效应。[结果]拔节孕穗期是小麦涝渍灾害最敏感阶段,也是补救措施恢复效果最佳时段;稻茬小麦耐涝渍性能较强,连续滞水7 d以上不会绝收;稻茬小麦涝渍后恢复能力较强,连阴雨渍害拔节期恢复指数最高可达36.00,孕穗期最高可达29.79,扬花灌浆期最高可达32.15。[结论]该研究可为小麦生产提供参考。

摘  要:
[Objective] Effect of waterlogging damage on wheat growth was studied,remedial measures were dicussed.[Method]Split plot design with remedial measures as main plots and occurrence period of waterlogging damage as subplots was adopted to analyze effect of occurrence period of waterlogging damage on wheat yield and yield components,explored recovery effect of different remedial measures. [Result]Wheat was the most sensitive to waterlogging damage in jointing-booting stage,and recovery effect of different remedial measures was optimal in the period. Waterlogging resistance of wheat was relatively strong,wheat can abtain yield after waterlogging 7 days continuously. Recoverability of wheat was relatively strong after waterlogging,maximum restitution index was 36. 00,29. 79,32. 15 in jointing stage,booting stage,grain-filling stage respectively when it rained continuously. [Conclusion]The research can offer reference for wheat production.
