Recently, the 2025 Ningbo Fine Grape Selection Event was held. 34 grape products from 24 business entities in the city participated in the competition, and 6 gold awards and 8 silver awards were finally selected. "Queen Nina" selected by Beilun Qingtai Fruit Professional Cooperative stood out and won the gold medal.

The planting of "Queen Nina" is full of challenges, especially the coloring link is the most critical and difficult. Zhu Mengding, the head of Qingtai Fruit Professional Cooperative, told reporters that he has gone through repeated experiments in the selection of seedlings, the promotion of coloring experiments, and the adjustment of soil fertilizer and water, and finally found the best combination and supporting methods.

At the same time, the district agricultural technology extension department, in conjunction with Qingtai Fruit Research Institute, has carried out a series of cultivation technology research and experimental demonstration since the introduction of "Queen Nina". Through three years' efforts, it has achieved considerable results. At present, the institute has basically solved the problem of difficult coloring of "Queen Nina" through technical measures such as three-film covering, panicle control and production control, laying reflective film, etc., and went on the market 20 days in advance to seize the local market.
