在水培条件下，以定期更换营养液和通气为对照（CK），研究了不更换营养液、定期通气（T1）和不更换营养液、不通气（T2）处理对菜心生长和品质的影响。研究结果表明，与对照相比，T1处理不影响菜心的生物量，而 T2处理显著降低了菜心的生物量；T1、T2处理显著提高了 VC 和可溶性糖含量，同时显著降低了硝酸盐含量。 T1处理可获得与对照相当的产量，并且可提高产品器官的营养品质、降低了硝酸盐含量，可作为菜心的简化水培管理模式。

In the hydroponic condition, taking the treatment regular renewal of nutrient solution and ventilation as the control (CK), we studied the effects of T1 treatment (non-renewal of nutrient solution but ventilating regularly) and T2 treatment (non-renewal of nutrient solution and ventilation) on plant growth and quality of flowering Chinese cabbage. The results showed that, compared with CK, T1 treatment didn't affect the biomass of flowering Chinese cabbage, while T2 treatment significantly reduced the biomass. In addition, T1 and T2 treatments significantly improved the vitamin C and soluble sugar content, while reduced the nitrate content significantly. T1 treatment could obtain quite the same yield of CK treatment, and improve the nutritional quality in product organs and reduced the nitrate content, thus it could be taken as a simplified management method for flowering Chinese cabbage under hydroponic condition.
