摘要
为解决芍药切花在栽培过程中易弯茎的问题,以黄金轮、银线绣红袍、紫凤朝阳3个芍药切花品种为试材,设置采收前喷施2%(CH3COO)2Ca、4%(CH3COO)2Ca、2%CaCl2、4%CaCl2共4个处理,通过株高、茎粗、蕾径3个指标的变化来比较不同钙素形态(有机态和无机态)和钙素浓度对植株茎杆增粗的效果,采用主成分分析法进行综合评价,结果表明,有机钙的效果优于无机钙;(CH3COO)2Ca的施用以4%较佳;喷钙对不同品种茎杆品质的影响不同,黄金轮和银线绣红袍在采前喷施4%(CH3COO)2Ca,可以明显提高茎杆品质,而紫凤朝阳不宜进行喷钙处理.
In order to solve the problem of stem curve of herbaceous peony cut flowers in cultivation,three varieties：Huangjinlun,Yinxianxiuhongpao and Zifengchaoyang were used in the research as plant materials to study the effect of different forms and concentration of Ca2＋.Altogether four different Ca2＋ treatments were arranged during the pre-harvest stage：2% CaCl2 and （CH3COO）2Ca,4% CaCl2 and （CH3COO）2Ca.Besides,principal component analysis was used to evaluate the different treatments synthetically.The results showed that：organic Ca2＋ was superior to inorganic Ca2＋;the best concentration of （CH3COO）2Ca was 4%;the effect of spraying Ca2＋ to the stem quality of herbaceous peony showed obvious differences among the three varieties.With 4%（CH3COO）2Ca,the stem quality of Huangjinlun and Yinxianxiuhongpao could be improved a lot while the calcium treatment was unsuited to Zifengchaoyang.
