以4~5年生巨峰葡萄为试验材料,设置了冬果结果母枝粗度、夏季修剪不同留芽数、修剪后涂抹破眠剂时间和冬果产量等处理,观察其对冬果生长及果实品质等的影响。结果表明,巨峰葡萄能正常萌芽、开花、着果、成熟,而且果实颜色及风味均表现良好,具备“两代不同堂”结果的潜力。夏季修剪时选择剪口粗度0.8cm以上、剪口留芽数5~6个、修剪后当天或第2天涂抹破眠剂芽萌发率较高,抽生的果枝健壮,果穗大,着果率高。
Taking 4 ~ 5-year-old Kyoho grapes as experimental material, the thickness of winter grapes, the number of buds in summer pruning, the time of pruning agent after pruning and the yield of winter fruit were set up to observe the effects on winter fruit growth and fruit Quality and other effects. The results showed that Kyoho grapes could germinate, flowering, fruiting and mature normally, and the fruit color and flavor all performed well, with the potential of “two generations of different” results. Select the summer pruning cutting width of more than 0.8cm, cut the number of buds left 5 to 6, the day after pruning or the first 2 days of application of sleep bud bud germination rate is higher, pumping fruiting branches robust, large ears, fruits High rate.
