摘　　要：采用随机区组设计研究了人工切割方式、植物生长调节剂种类和植物生长调节剂浓度 3 个因素对石蒜子球性状的影响。结果表明:(1)和自然分球相比,人工切割繁殖可明显提高石蒜子球的繁殖系数,其中切片扦插法可获得较多数量的子球,但子球较小;茎盘刳取法正好相反;茎盘沟切法和伤心法获得子球的数量和质量都较高,可推广使用;(2)ASL、IBA和NAA的混合液对石蒜子球数量的增加有促进作用,GA3、2,4 D对石蒜子球的产生有明显的抑制作用;(3)以500 mg/L的ASL+IBA+NAA的混合液处理效果最好,800 mg/L的次之,1 000 mg/L的最差。Lycoris radiata is an important ornamental plant in autumn and winter,but its natural propagation coefficient is low.In order to study the effects of the ways of the artificial propagation,the plant growth regulators and the consistence of the plant growth regulators on the quantity and the quality of bulb scales of L.radiata,an experiment of the artificial propagation,was arranged,based on randomized blocks design.The results were as follows:(1)Compared with natural propagation coefficient of L.radiata scale bulblet,the artificial propagation coefficient was much higher.By fractional scale-stem cutting,more but the smallest scale bulblets could be obtained from one bulb.By notching,the least but biggest bulblets could be got.By scoring and boring,more and bigger scale bulblets could be attained.((2)ASL) and IBA+NAA had the best effect on increasing the quantity of bulblets;GA 3 and 2,4-D inhibited the quantity of bulblets.(3)The effect of consistence of ASL+IBA+NAA on the quantity of bulblets showed that high consistence could inhibit the quantity of bulblets and low consistence could increase the quantity of bulblets.
