在不同输气灌溉条件下,对大棚秋黄瓜的产量及其发育过程中叶片的生理生化特性进行了比较研究。结果表明,1天3次和1次的输气处理与对照相比,秋黄瓜的产量分别增加30.38%和43.02%,在不同的生育阶段叶片的叶绿素、可溶性蛋白质和可溶性糖的质量分数均有不同程度的增加,叶片的光合速率得到显著增强。输气灌溉促进了秋黄瓜植株的生长,增强了植株根茎叶的整体功能,提高了结实率,最终使得秋黄瓜的产量得到显著增加。
Under different irrigation conditions, the yield and the physiological and biochemical characteristics of autumn cucumber in greenhouse were compared. The results showed that the yield of autumn cucumber increased by 30.38% and 43.02% respectively compared with the control when the gas was supplied three times a day and once. The mass fraction of chlorophyll, soluble protein and soluble sugar in leaves at different growth stages were With different degrees of increase, photosynthetic rate of leaves was significantly enhanced. Gas-flow irrigation promoted the growth of autumn cucumber plants, enhanced the overall function of plant rhizomes and leaves, increased the seed setting rate and finally increased the yield of autumn cucumber.
