旱涝急转对大豆产量和生长发育影响OA

To study the impact of rapid transitions between drought and flood on soybean yield and growth development,a com-parative 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.
