旱涝急转对大豆产量和生长发育影响

The impact of rapid transition between drought and flood on soybean yield and growth development

为研究旱涝急转对大豆产量和生长发育的影响,通过开展旱涝急转组、单旱组、单涝组和对照组平行对比形式的旱涝急转测筒试验,分析了大豆不同试验处理条件下叶绿素含量变化规律、大豆前期受旱再继续受涝的产量变化规律以及不同旱涝组合形式下先旱与后涝相互作用的产量变化规律,进一步探究了旱涝互作对产量构成因素的影响。研究成果为旱涝急转防灾、减灾提供理论依据和技术支撑。

To study the impact of rapid transitions between drought and flood on soybean yield and growth development,a comparative test using drought-flood transition test cylinders was conducted,including groups for drought-flood transition,single drought,single flood,and a control group.The study analyzed the changes in chlorophyll content under different experimental conditions,the yield variation of soybeans subjected to drought followed by continued flooding,and the yield variation under different drought-flood combination scenarios,focusing on the interaction between initial drought and subsequent flooding.The research further explored the effects of drought-flood interactions on yield components.The findings provide theoretical support and technical backing for disaster prevention and mitigation in rapid drought-to-flood transitions.
