宁夏贺兰山东麓葡萄抗抽干能力与抗晚霜冻危害能力调查

Investigation on the Anti-dry Ability and Resistance to Late Frost Damage of Grapes in Helan Mountain,Ningxia

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。

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.
