Abstract

Abstract:

Using Ding'ao bayberry from Chashan, Wenzhou as the experimental material, this study explored the effects of different trellis on the yield and fruit quality of Chinese bayberry. The results showed that under stand-picking conditions, single plant yield of Chinese bayberry with full steel pipe vertical trellis was 43.44 kg, with a commercial fruit rate of 72.75%, which increased by 121.18% and 28.99 percentage points compared with the control. Both full steel pipe vertical trellis and bamboo flat trellis did not affect the appearance and quality of Chinese bayberry fruit, which were beneficial for reducing total acid content and increasing sugar-acid ratio. Chinese bayberry with full steel pipe vertical trellis was more delicious, with total flavonoid, total amino acid, and glucose contents of 1.19, 8.31, and 8.08 mg·g^-1, which were 14.42%, 8.63%, and 15.26% higher than that of control. The total acid content was 9.78 g·kg^-1, a decrease of 6.50% compared with the control. The sugar-acid ratio was 25.96. In summary, the use of full steel pipe vertical trellis has a significant effect on improving the yield, fruit quality, commercial fruit rate, and high-quality fruit rate of Ding'ao bayberry.

Key words: Chinese bayberry, Ding'ao bayberry, steel pipe, vertical trellis, yield, fruit quality
