| 摘 要： | 对上海地区葡萄促成栽培的几个主要品种的休眠需冷量进行了调查,发现在供试的5个品种中以里扎马特的需冷量最低,自然条件下仅为447.5h;其次为京亚和巨峰,需冷量均低于1000h;绯红和无核白鸡心需冷量最高,均超过1000h。由此推算,上海地区葡萄结束自然休眠的时间在1月上旬至2月中旬。打破休眠的试验表明以20%石灰氮12月中旬处理效果最佳。

| Abstract: | During1998～2000experiments were conducted with5leading grape cultivars under forced grown conditions in Shanghai area for studying their chilling requirement (CR,hours below7.2℃).The CR value of cultivars investigated under natural conditions showed that Rizamat was the lowest,only447.5h;Jingya and Ky oho were below1000h;Cardinal and Centinnal seedlees were the highest,both above1000h.So it could be concluded that the completion of grape dormancy in Shanghai area was from early January to mid Febru ary.Different dormancy breaker used at different stages indicated that us-ing20%Ca (CN) 2 in mid De cember had an optimal effect.Some discussions were given in the end. |
