基于涝渍胁迫测桶系统的小麦渍害试验研究OA

To study the impact of waterlogging stress on wheat yield,this article has been conducting waterlogging damage research on wheat.Twelve measuring barrels were set up at the agricultural water conservancy scientific research station located in Jiangdu,Yangzhou,equipped with Markov bottles to control the water level inside the barrels,and to explore the changes in wheat morphology,physiology,and yield under different degrees of waterlogging.The conclusion indicates that,except for severe waterlogging that affects the growth of wheat root system quantity,other morphological indicators are less affected;Soil moisture and photosynthesis in physiological indicators are greatly affected by waterlogging,while chlorophyll content is less affected;wheat yield is greatly affected by waterlogging,with moderate and severe waterlogging causing a decrease in yield,averaging 1.64%and 6.71%respectively.
