巨峰确定为我省保护地栽培品种后,近几年内发展很快,特别适于小面积家庭栽培,深受群众欢迎。但是巨峰葡萄落花落果严重。就这个问题,齐齐哈尔园艺所报导花期蘸1％B_θ果粒数增加2倍,穗极紧,但单粒重减少;另据报导日本在盛花前26～4天分四期用2,500PPmB_9蘸花序,促进了巨峰有核果座果,4天前处理的促进了无核果座果。为了进一步验证B_9处理解决巨峰落花落果重的效果,对巨峰果穗做了不同时期,不同浓度的B_9处理试验。
Jufeng identified as a protected cultivated varieties in our province developed rapidly in recent years, especially for small-area family cultivation, welcomed by the masses. However, Kyoho grapes fall seriously. On this issue, Qiqihar Horticultural Institute reported that the flowering date dipped 1% B_θ fruit number increased by 2 times, spike very tight, but single grain weight reduction; also reported in Japan 26 ~ 4 days before flowering in four phases with 2,500PPmB_9 dipped inflorescence, Promote the Jufeng has drupes, 4 days ago to promote the treatment of fruitless fruit. In order to further verify the B_9 treatment to solve the problem of the weight of the fruit falling from the peak, fruit of Jufeng made different periods, different concentrations of B_9 treatment test.
