摘 要：
以6年生‘北红’‘北玫’葡萄植株为试材,调查其在宁夏贺兰山东麓葡萄酒产区的存活率、抗抽干能力及遭受晚霜冻危害程度,以期为‘北红’‘北玫’在该产区的引种提供参考依据。结果表明:在宁夏贺兰山东麓产区,‘北红’‘北玫’葡萄虽可以进行免埋土越冬栽培,但经过2013—2017年栽培种植,分别有13.5%和25.0%葡萄植株死亡;2018年分别有34.7%、46.0%的植株发生不同程度的抽干,其中8.1%、10.0%的植株会完全抽干死亡;在遭受晚霜危害(2018年4月7日)后,平均每株萌芽率为35.3%和30.5%,平均花序数为每株7个。进一步证明‘北红’‘北玫’在宁夏贺兰山东麓产区仅可作为调配品种栽培,不宜大面积推广种植。

摘 要：
By investigating the survival rate,anti-sucking ability and the degree of late frost damage of the 6-year-old 'Beihong' and 'Beimei' grape plants in the east foothills of Ningxia Helan Mountain.The results could provide a theoretical basis for the introduction of these two varieties in the producing area.The results showed that in the northeastern Helan region of Ningxia,the 'Beihong' and 'Beimei' grapes could basically survive in soil-free winter,but after five years of cultivation(2013—2017),there was still 13.5% and 25.0% of the vines died.In the sixth year(2018),34.7% and 46.0% of the plants were drained to different degrees,8.1% and 10.0% of the plants were drained and died.After suffering from the early spring germination(April 7,2018),the average germination rate per plant was 35.3% and 30.5%,and the average number of inflorescences was 7 per plant.It is further proved that 'Beihong' and 'Beimei' could only be cultivated as blending varieties onthe east foot of Helan Mountain,Ningxia,but not advocated to large-scale planting.
