铁皮石斛2种采收方式的比较(1)
http://www.100md.com 2015年3月1日 中国中药杂志 2015年第5期
     [摘要] 为了规范铁皮石斛采收方式,提高药材质量与产量,通过田间试验、多糖与浸出物含量的测定,比较保留母条与全采2种采收方式对铁皮石斛农艺性状、产量与质量的影响。结果表明,采收方式显著地影响铁皮石斛生长,保留母条能显著地促进铁皮石斛萌蘖数和茎长、茎节数、茎节间距的生长,提高单位面积茎鲜重、叶鲜重、总鲜重、茎干重,对茎粗、茎中多糖含量没有促进作用。铁皮石斛采收过程中,适度保留部分母条,有利于促进新芽萌动与生长,提高铁皮石斛药材的产量,并可通过调整栽培密度与光照保证多糖含量。

    [Abstract] To standardize the harvest ways of Dendrobium officinale and improve the quality and yield of D. officinale, a field experiment was carried out to study the effect of two kinds of harvest ways, which were keeping some of the axial shoot and harvesting all of the shoot by the end of the year. Then, the agronomic traits and yield were measured and the contents of polysaccharides and extractum were determined. The results showed that the harvest ways significantly affected the growth of D. officinale. Keeping some of the axial shoot could significantly improved the number of sprout, stem length, internode number and the internodal length, which also triggered increase the weight of fresh stems, leaves and the total of them and dry stems in per unit area, but it could not promote the stem diameter and the polysaccharide content in stems. Keeping some of the axial shoot moderately was conducive to the improvement of the production of medicinal materials in the process of harvesting by promoting the germination and growth of new buds, and to ensure the polysaccharide content by regulating the illumination and the density of cultivation.

    铁皮石斛Dendrobium officinale Kimura et Migo是传统名贵珍稀中药材,具有益胃生津、滋阴清热等功效[1]。目前,铁皮石斛主要采收方式有种植4~5年时全草采收、每年采净地上全部萌条(全采)与保留部分母条(保留母条)3种方式。为了揭示采收方式对铁皮石斛农艺性状、产量和有效成分含量的影响,提高人工栽培铁皮石斛的质量与产量,作者开展了全采与保留母条2种采收方式的田间试验,并对所产药材的多糖、浸出物进行了比较。

    1 材料与方法

    1.1 田间试验 2010年10月18日—10月25日,选择6A×2B,9×66,17×71,30×83,65×91,124×140等 6个铁皮石斛优良品系,在浙江省义乌市佛堂镇高效生态农业示范园区丹溪药博园建立试验地。试验地采用随机区组试验设计,重复3次,环境条件与试验方法见文献[2]。2013年2月6日,每个小区50%采净地上的全部萌条,50%保留2012年萌发的长度5 cm以下的萌条(约占总生物量的20%)。2014年1月3日至1月5日,每个小区保留母条和全采试验地分别采收50丛2013年萌条,测定总鲜重、茎鲜重和叶鲜重,以及每丛萌蘖数、萌条茎节数、萌条长度和茎中部直径并换算出茎节间距(株高/茎节数量)。, 百拇医药(王洋 诸燕 斯金平 刘京晶 朱玉球 刘秀娟)
