红豆杉，是世界上公认濒临灭绝的天然珍稀抗癌植物，是经过了第四纪冰川遗留下来的古老孑遗树种，在地球上已有250万年的历史。近年来，红豆杉已经成为植物界的“名星”。它在花卉市场很火热，不少花友都会买一盆红豆杉。那么有花友就问小编，红豆杉是几年开花结果的？亲，我们一起往下看看吧！

红豆杉开花结果的时间

红豆杉需要几年开花结果：

红豆杉结果的问题需要具体分析，不同品种的红豆杉结果年限也不同。

首先花友要知道红豆杉为雌、雄异株，异株授粉才能结果，需要所栽种的红豆杉里面同时有雌株和雄株，如果家里有一盆红豆杉，那是结不了果的。

南方红豆杉结果时间为7-8年树龄，雌雄异株，花期4-5月，挂果期6-11月。果实形如樱桃、色如红宝石，挂在枝叶上面非常好看。果实可观赏，可食用。 红豆杉结果前无法分辨雌雄，同时会由于环境及气候等因素的变化，雌雄之间会发生转变。经过长期培育养护经验证明，雌树比例远远大于雄树。

曼地亚红豆杉属雌、雄异株，雌、雄比例按 9:1 栽种；雌株经过4-5年栽种，能开花结果，花期 4-5 月，挂果期 6-11 月。果实生在前一年的结果母枝上，雌株修剪时要确保结果母枝的数量，以便次年红豆杉结果。

当然也有的花友的红豆杉三年苗就结果了，这主要是由于植株是扦插的，并非实生苗。

拓展知识-红豆杉的价值：

1、经济价值

据《人民日报》2001年10月17日第五版报道，2000年国际市场上优质紫杉醇的售价已高达每千克18万美元。心材桔红色，边材淡黄褐色，纹理直，结构细，比重0.55-0.76，坚实耐用，干后少开裂。可供建筑、车辆、家具、器具、农具及文具等用材。

2、药用价值

癌症药物的新来源：紫杉酵（taxol）是一种有效且常用的癌症药物，但它目前仅能采自于一种濒危植物的针状叶，人们对该药的需求很可能超出这种树的生产能力。

3、绿化价值

红豆杉树形美丽，果实成熟期红绿相映的颜色搭配令人陶醉，可广泛应用于水土保护和林、园艺观赏林，是新世纪改善生态环境，建设秀美山川的优良树种。

在园林绿化，室内盆景方面也具有非常广阔的发展前景，如利用珍稀红豆杉树制作的高档盆景，在北京、上海、深圳等地卖到30万元/盆，成为城市绿化和家居美化新贵，被人们形象地称为珍贵的“摇钱树”。

红豆杉能很好地净化室内的空气，吸收室内的毒气如新房装修时的甲醛都能很好地被吸收，而降低毒气在室内的含量。红豆杉本身能吸收二氧化碳，释放出氧气，是个白天晚上都可以用的天然的氧吧，属于CAM类树种，可以预防呼吸道疾病，保持空气的清洁度和安全度。经现代环境监测证明，红豆杉对很多毒气比如二氧化硫、一氧化碳等都具有吸收进体内，净化室内空气的作用。
