摘要
为探索涝渍胁迫对农作物生长及产量的影响规律,对涝渍条件下棉花的形态特征量、生理特征量、产量和干物质重量等要素进行了试验观测,对比分析试验数据后发现,涝渍胁迫条件下棉花的形态特征量会发生变化,并进而影响生理特征量,最终导致产量和干物质重量发生变化。通过分析棉花形态变量、生理变量、土壤水分变量等要素之间的关系,建立了涝渍胁迫条件下作物的4个水分生产函数新模型,模拟结果与实测数据十分吻合。
In order to evaluate the effects of waterlogging stress on the crop growth and yield, the morphological characteristics, physiological characteristics, yield, and dry matter weight of cotton under waterlogging stress were measured. The comparative analysis of test results suggested that the morphological characteristics of cotton varied under the waterlogging stress, which can affect the physiological characteristics and eventually result in the variation of yield and dry matter weight. The relationships a-mong the morphological characteristics, physiological characteristics, and soil moisture of cotton were analyzed, and four new models of crop water production function were developed under the waterlogging stress. These models generated similar results of crop yield compared to the observed data.
