经过多年的野外调查及查阅相关资料,基本上摸清了野生川榛资源在安徽省的分布范围。从大别山区的金寨县引种野生川榛于江淮丘陵区的肥西县栽培,观察生长开花习性和物候期,测定果实经济性状及摸索栽培技术。连续3年引种观察表明,将高海拔地区的野生川榛引种至低海拔地区栽培能够正常生长、开花、结实;坚果单果重1.3 g,种仁重0.6 g,壳腰厚度1.2 mm,出仁率46.3%,空瘪率低于10%;引种栽培初步成功。
The distribution range of wild resources of Corylus heterophylla var. Sutchuenensis in Anhui Province was basically identified through years of field survey and review of relevant information. Wild plants of Corylus heterophylla var. Sutchuenensis in Jinzhai County in Dabie Mountains were introduced and cultivated in Feixi County in Jianghuai hilly region to observe their growth and flowering characteristics and phenophase, measure the economic characters of their fruits and explore their cultivation techniques. 3-year consecutive introduction observation showed that the plants of Corylus heterophylla var. Sutchuenensis introduced from the high-attitude region and cultivated in the low-attitude region could grow,bloom and bear fruit normally with the single nut fruit weight being 1.3g, kernel weight being 0.6g, shell thickness being 1.2mm, kernel rate being 46.3% and empty rate lower than 10%. The introduction and cultivation had initial success.
