| 摘 要： | 采用盆栽试验,通过控制不同灌溉下限,研究了黄瓜初花期的不同土壤水分状况对其植株生理指标、形态指标、产量、品质和水分利用效率的影响.结果表明:初花期和盛瓜期各光合参数(光合速率、气孔导度、蒸腾速率)的日变化为单峰曲线,初瓜期各光合参数的日变化为双峰曲线.气孔导度和蒸腾速率均与光合速率基本呈现相同的变化规律.不同土壤水分状...

| Abstract: | Physiological indexes,morphological indexes,yield,fruit quality and water use efficiency of cucumber were studied under different soil irrigation minimums during initial bloom stage in pot experiment.The results showed: the diurnal course of physiological indexes of cucumber was displayed in single peak pattern curves in initial fruit stage and mid-fruit stage,while the diurnal course of physiological indexes of cucumber was displayed in a two-peak pattern curve in early-fruit stage.Stomatal conductance,tra... |
