摘要
对在甘肃核桃主产区引进的10个核桃栽培品种从树种特性、坚果品质、丰产性、抗逆性等4方面进行综合性状评价,筛选出‘丰辉’‘清香’‘辽宁4号’‘中林1号’等品种综合性状优良,可作为甘肃核桃主产区集约化生产的主栽品种;‘元丰’粗脂肪、矿物质养分高,产量高,但坚果果个小,可作为油用品种规模化栽培;‘晋龙1号’‘晋龙2号’前期产量低,但树体高大、抗性好,可在劳动力少、土地充裕地区作为生态经济林适宜发展。
The paper focus on different introduced Juglans regia cultivars in main producing areas of Gansu province. The comprehensive traits including species characteristics, nut quality, yielding ability, and stress resistance of ten Juglans regia cultivars were evaluated, the result shows ‘Fenghui＇, ‘Qingxiang＇, ‘Liaoning 4＇, ‘Zhonglin 1＇ can be used as the main cultivars for their excellent comprehensive traits. ‘Yuanfeng＇ has high crude fat contents and mineral nutrients contents, the yield is also high, and it can be used as oil variety. The yield of ‘Jinlong 1＇ and ‘Jinlong 2＇ is lower in the yourth-stages, it can be developed as ecological economic forest in low labor and abundant land areas because of large-scale tree shape and good stress resistance.
