广西桃早熟品种“四月红”不同基质的扦插生根效果研究

以早熟桃"四月红"为试材,河沙 苔藓、纯河沙、纯火土、火土 苔藓、黄泥土、黄泥土 苔藓为基质,开展扦插试验,以筛选出"四月红"扦插繁殖的最佳扦插基质.结果显示:以河沙 苔藓为基质的生根率、根数量,根长和根粗4方面的指标均显著高于其它基质的;根据隶属函数法的综合评价,几种类型基质的扦插效果为河沙 苔藓＞纯河沙＞黄泥土＞纯火土＞黄泥土 苔藓＞火土 苔藓.由此可见,河沙 苔藓是"四月红"桃扦插繁殖的最佳基质.

Effects of Different Substrate on Cutting Rooting of a Early-ripening Peach Cultivar Siyuehong in Guangxi

Based on a early-ripening peach cultivar 'Siyuehong' and 6 types of substrate i.e.sand moss,sand,ash soil,ash soil moss,yellow upland soil,yellow upland soil moss,the cutting propagation experiment was carried out for filtering the best substrate.The results showed that,in terms of 4 indexes of rooting ratio,rooting number,rooting length and rooting diameter,sand moss appeared to be more significantly effective than others;according to comprehensive appraisal of cutting effect about substrate with subordinate function,the order was sand moss>sand>yellow upland soil>ash soil>yellow upland soil moss>ash soil moss.Therefore,sand moss was appropriate to cutting propagation for early-ripening peach cultivar 'Siyuehong'.
