试验设在扬州大学农学院6年生葡萄园,供试巨峰株行距1m×1.5m,篱架栽培,管理水平中等。CA_3浓度50mg/l,链霉素(SM)浓度100mg/l,CA_3+SM浓度为(50+100)mg/l。第1次处理在盛花前5天(5月10日)浸花序,第2次为盛花后5天(5月20日)浸穗。结果表明,链霉素能增加果穗着果数,减轻落花落果;赤霉素能促进无籽果形成,盛花期前处理显著优于花后处理。对巨峰葡萄在花前5天浸
The experiment was located in the 6-year-old vineyard of Yangzhou University College of Agriculture, for the test Jufeng line spacing 1m × 1.5m, fence cultivation, management level is medium. The concentration of CA_3 was 50 mg / l, the concentration of streptomycin (SM) was 100 mg / l and the concentration of CA_3 + SM was (50 + 100) mg / l. In the first treatment, the inflorescence was infested for 5 days before the full bloom (May 10) and the second for 5 days after the full bloom (May 20). The results showed that streptomycin increased the number of fruit per ear and reduced the number of fallen fruit; gibberellin could promote the formation of seedless fruit, which was significantly better than that of anthesis after full bloom.
