Abstract:

In 2020，Tianjin introduced the early maturing grape variety Tiangong Moyu from Zhejiang Academy of Agricultural Sciences and conducted continuous observation of its introduction for three years in gutter-connected plastic greenhouse. The results indicated that Tiangong Moyu exhibited good flower bud differentiation，strong growth vigor，and strong disease resistance in Tianjin area. The fruit matured in late July，with an average ear weight of 502.61 g，an average grain weight of 6.47 g，an average vitamin C content of 31.47 mg·kg^-1，an average soluble solids content of 19.4%，and an average titratable acid content of 0.43%. The ripening period was 7-9 days earlier than that of Xiahei. This article mainly summarized the key technical measures such as structure of trellis and tree shape，flower and fruit management，water and fertilizer management，and pest control under this cultivation model，in order to provide reference for the promotion and planting of Tiangong Moyu in gutter-connected plastic greenhouses in Tianjin or other similar areas.

Key words: Tiangong Moyu, introduction performance, phenological phase, variety characteristic
