北榛南移的适生品种筛选

Selection of Suitable Varieties for Northern Hazel Migrating to the South

[目的]筛选适应性强、结实状况良好的适宜安徽地区的平欧杂交榛推广品种。[方法]对平欧杂交榛由东北地区引种至安徽地区6年后的结果树进行适应性、物候期、生长量、产量等比较。[结果]与原产地栽植密度相同的情况下,达维的适应性最强,且单株产量可达到2 128 g/株,产量近3 750 kg/hm^(2),与原产地东北地区差异不显著;引种品种物候期比东北地区提前20~30 d,榛果提前30 d采摘上市,大大提高了经济效益;达维、玉坠、平欧110、平欧226和平欧524之间树体及果实性状差异显著,其中达维生长表现最好,适应性最强,平欧524稍次。[结论]在安徽地区进行平欧杂交榛引种栽植,可为扩大其栽培范围提供依据。

[Objective]To screen out varieties suitable for Anhui region with strong adaptability and good fruiting conditions. [Method]This paper compared the adaptability, phenological period, growth, yield, etc. of the fruiting trees 6 years after the introduction of hybrid hazelnutnut from the northeast region to the Anhui region. [Result]The results showed that under the same planting density as the origin, Dawei had the strongest adaptability, and the yield could reach 2 128 g/plant, and the yield was nearly 3 750 kg/hm^(2), which was not significantly different from the northeast region of the origin;the phenological period of the introduced varieties was higher than that in the northeast region. 20-30 days ahead of schedule, hybrid hazelnut nuts were picked one month ahead of schedule, which greatly improves economic benefits;there were significant differences in tree and fruit traits among the five varieties of Dawei, Yuzhui, Pingou 110, Pingou 226 and Pingou 524, among which Dawei has the best growth performance and the strongest adaptability. [Conclusion]The introduction and planting of Ping-Europe hybrid hazelnut in Anhui area provides a basis for expanding its cultivation range.
