摘要： 本研究以四季小白菜为试材,采用300 mg·L-1富氢水(HRW)结合营养液进行水培,系统探究其对小白菜生长指标、生理机制及品质形成的影响。结果表明:富氢水处理后小白菜株高、冠幅、叶片数和根长均显著高于对照,小白菜地上部鲜重和干重分别比对照提升了63.59%和47.87%,富氢水处理显著促进小白菜的生长和生物量的积累。富氢水处理后,小白菜叶片净光合速率、气孔导度、叶片SPAD值和叶绿素含量均显著高于对照。根系活力较对照提高了102.24%。品质分析显示,富氢水处理后,小白菜可溶性蛋白含量和纤维素含量均有所增加但差异不显著。综合分析试验结果可知,富氢水处理显著提高了小白菜的株高、冠幅、叶片数、根长和叶绿素含量,促进了光合作用和生物量积累,提高了植株的根系活力。本研究为富氢水在水培蔬菜中的应用提供了理论依据。

Abstract:

In this study, Chinese cabbage was used as the test material, and 300 mg·L-1 hydrogen-rich water was carried out with hydroponics combined with nutrient solution, and its effects on plant growth indexes, physiological mechanism and quality formation were systematically explored. The results showed that the plant height, crown width, leaf number and root length of Chinese cabbage were significantly higher than those of the control, and the fresh weight and dry weight of the above-ground part of Chinese cabbage increased by 63.59% and 47.87%, respectively, indicating that hydrogen-rich water treatment had a significant effect on the growth and biomass of Chinese cabbage. After hydrogen-rich water treatment, the net photosynthetic rate and stomatal conductance of Chinese cabbage leaves, the SPAD value and chlorophyll content of leaves were significantly increased compared with the control. Root activity increased by 102.24% compared with the control. The quality analysis showed that the soluble protein content and fiber content both increased, but the difference was not significant. The results showed that hydrogen-rich water treatment significantly increased the plant height, crown width, leaf number, root length and chlorophyll content of Chinese cabbage, promoted photosynthesis and biomass accumulation, and improved the root vigor of plants. This study provides a theoretical basis for the application of hydrogen-rich water in hydroponic vegetables.
