在测坑和小区中对油菜进行多过程受渍试验,研究发现油菜各生长阶段地下水连续动态与其相时产量存在显著负线性相关关系,油菜各生长阶段的受渍敏感因子和减产速率因子不同,以花期最大,结果期最小;油菜抑制天数指标与其相对产量存在显著负线性相关关系.对油菜累积减产指标进行探讨,发现油菜累积减产指标与其相对产量也存在显著负线性相关关系.

This study discovers that there exists a negative linear relationship between continuous groundwater dynamic and relative yield during the growth period duration of rape by multi-process experiments in the test-pits and small districts under the condition of subsurface waterlogging. The sensitive indexes and velocity of yield decrease factor of rape suffering from waterlogging are evidently different in different growth period durations,with the maximun in the blossoming stage and the minimum in the fruiting stage. There exists a negative linear relationship between stress day index and the relative yield of rape and there also exists a negative linear relationship between accumulative yield decrease index and the relative yield.
