The invention discloses a hydroponic propagation method for Amorphophallus konjac Mini species, which belongs to the field of agricultural breeding and breeding technology. The method is to divide the stem of the Amorphophallus konjac tissue culture seedling which is 4 ~ 5cm high with the knife to divide the petiole of the seedlings and the tumor like callus in the base. The tissue culture seedlings are coated with sponges in the base part after washing with water. The plant is implanted with tap water in the indoor hydroponic culture and the tissue culture seedlings are sprayed once every 7 days after the growth of the N:P:K:Ca:Mg matter every 7 days. The nutrient solution of 23:1:21:4:1, with a total concentration of 225mg/L, was 10~15 C in the night and 20~25 in the daytime. The light was scattered light in the daytime. After 3 months of water culture, no hydroponic culture was carried out, and the plants could be naturally inverted, and the mature miniature taro could be harvested. This method can produce an average of 1.5 grams of konjac micro - taro in three months, which greatly shortens the reproduction cycle of the konjac high quality taro, the production cost is low, the survival rate and the yield of taro reach 85 90%.

一种魔芋微型种芋的水培繁种方法
本专利技术涉及一种魔芋微型种芋水培繁种技术,属农业育种与繁育
技术背景魔芋(konjac)为天南星科魔芋属多年生草本植物,主要以球茎进行无性繁殖,魔芋目前已能通过植物组织培养生物技术繁育出优良种苗并移栽到苗床进行良种繁育,为魔芋种性退化、优良种芋奇缺提供了行之有效的解决方法。但魔芋组培苗的栽培管理是一项十分精细的工作,技术操作和栽培条件稍不注意将会大大降低组培苗的成活率和结芋率,且生产优质种芋的周期较长,需一个生长周期(6—8个月)。因此,寻找一种既能缩短魔芋微型种芋的繁种周期,又易于繁育的方法是本领域科技人员长期想探索的技术问题。迄今为止,未见通过水培技术在较短的时间(3个月)内繁殖出魔芋微型种芋的公开报道。
技术实现思路
:本专利技术要解决的技术问题是克服现有魔芋微型种芋组培快中魔芋组培苗的栽培管理技术操作和栽培条件要求高,易导致组培苗的成活率和结芋率大大降低,且生产优质种芋的周期较长的技术缺陷和不足。其目的是提供一种既能缩短魔芋优质种芋的繁殖周期,繁种操作又简便,易于成活、能降低优质种芋的生产成本的方法。为解决上述技术问题和达到本专利技术目的,本专利技术提供了一种魔芋微型种芋的水培繁种方法,该方法按现有技术对魔芋进行植物组织培养,其特征在于:(1)将植物组织培养生产出的苗高为4cm—5cm的未生根的魔芋组培苗切割,切割是将该苗的叶柄与其基部的瘤状愈伤组织分割开,然后用自来水冲洗去组培苗基部的培养基后,用海绵包裹组培苗基部,再植入穴盘中用自来水在室内水培,组培苗水培生长7天后,每隔7天喷施一次N:P:K:Ca:M ...
