大果沙棘形态与结实特征效果评价研究

Evaluation on Morphological and Fruiting Characteristics of Large Fruit Sea Buckthorn

针对中国野生沙棘果小、多刺、难采摘,生产中不能大规模推广种植等方面的缺点,近年来开始从俄罗斯引进优良沙棘品种(大果沙棘)。通过开展8个大果沙棘品种在哈尔滨地区的栽培实验,观测不同品种大果沙棘在当地生长适应性、形态特征以及结实情况,通过建立量化评价指标体系对大果沙棘开展综合评价。结果表明,在哈尔滨地区,无刺丰表现最佳,可以作为推广栽培的优选品种;丘伊斯克等5个品种表现尚可,有一定推广价值;辽阜1号和契切克的表现最差,不建议作为推广首选品种。

Chinese Sea buckthom has several shortcomingsin small fruit, spiny, hard to harvest and unsuitable for large - scale planting and so on. In recent years, Russian Sea buckthom varieties （large fruit sea buckthorn） were introduced to China. By the euhivation experiment on 8 varieties in Harbinarea, this study observes their growth adaptability, morphological character- istics and the fruiting characteristics, establishment a quantitative evaluation index system to carry out a comprehensive evaluation of 8 varieties. The results showed that in Harbin area, the best one is Wucifeng which can be used as a preferred varieties for culti- vation. 5 varieties such as Qiyisike have an acceptable performance, which means that they have certain promotion value. Liaobu No. 1 and Qiqieke are not recommended due to their poor performances.
