不同果桑品种的引种栽培试验

目的]进行7个果桑品种的引种栽培试验。方法]2014年引进7个果桑品种(大十、红果2号、四季2号、台湾超级长果、果选2号、珍珠白、桂花蜜),并连续4年对其进行引种观察,比较其树体特征、物候期特征、结果习性特征。结果]7个果桑品种中,6个品种适应性表现较好,能正常生长结果,只有台湾超级长果越冬时新稍冻死,从而影响其长势、产量。其中,大十、四季2号在引种地表现优良;大十出芽时间早、长势优良、叶形大、分枝数多,产量高;四季2号长势、产量次之,但口味甜,果色紫黑色,果质优良。桂花蜜、珍珠白发芽迟,成熟晚,能延长果桑采摘期。结论]大十、四季2号能作为优良品种在湖北省宜昌市夷陵区推广;桂花蜜、珍珠白可作为晚熟品种进行辅助推广。

Introduction and Cultivation Experiment of Different Cultivars of Fruit Mulberry

Objective] To carry out the introduction and cultivation experiment of different cultivars of fruit mulberry .Method] Seven cultivars of fruit mulberry(Dashi,Hongguo 2,Siji 2,Taiwan Super Long Fruit,Guoxuan 2,Zhenzhubai,Guihuami) were introduced in the year of 2014, and introduction observation of continuous four years was carried out .Their tree characters, phenological feature and fruiting habit were compared . Result] Among the seven cultivars of fruit mulberry, six cultivars showed relatively good adaptation and had normal growth and fruiting.Only the shoot of cultivar Taiwan Super Long Fruit was freezed to death in terms of wintering , so that the growth vigour and yield were affected .Dashi and Siji 2 showed excellent performance in introducing area.Dashi had early germination time, good growth vigor, big leaf shape, many branching number and high yield.Siji 2 had poorer yield and growth vigor, but sweet taste, purple black fruit, and good fruit quality.Guihuami and Zhenzhubai showed late germination and mature date, and could prolong fruit-picking stage.Conclusion] Dashi and Siji 2 could be extended in Yiling District, Yichang City, Hubei Province as the high quality varieties;while Guihuami and Zhenzhubai could be extended as supplemental late mature varieties.
