Abstract:

In order to select excellent fast-growing Chinese cabbage varieties suitable for cultivation during the summer high temperature period in Zhejiang Province, 16 Chinese cabbage varieties were introduced for comparative production experiments during the summer high temperature period and laboratory high temperature simulation experiments, and their main botanical and yield traits were investigated. The results showed that the seedling-type Chinese cabbages varieties Zaoshu 8, Zheyan Lvjian, Shenrong Huojian Kuaicai, and the pakchoi varieties Xinfu Rekang Wang and Jinpin Yanxiu exhibited superior performance in terms of commercial value, yield, and resistance. These varieties are suitable for cultivation and promotion in Zhejiang Province during the summer. Additionally, a suite of green cultivation techniques was integrated, encompassing water and fertilizer management, facility environment regulation, and pest and disease prevention and control.

Key words: fast-growing Chinese cabbage, high temperature, variety comparison, green cultivation
