摘　　要：为探索无毛小白菊扦插育苗的最佳时间和天气,培育优质壮苗,供菊花栽培生产上应用。选用无毛小白菊枝条顶梢的嫩枝为试验材料,研究不同季节和天气对无毛小白菊扦插成活率及生根的指标,结果表明:4月扦插最好,苗木成活率平均达99.75%,较7月和9月扦插的分别提高22.25%、3.50%;须根数4月扦插的达16.08条,较7月和9月扦插的分别提高85.90%、22.75%;须根长度4月扦插的达3.68 cm,较7月和9月扦插的分别提高55.93%、15.00%。阴雨天扦插苗木成活率比晴天扦插的提高4.50%、须根数提高32.04%、须根长度提高12.29%。由此可见,无毛小白菊应以4月的阴雨天扦插繁殖为佳。To explore the optimal time and weather conditions for cuttings propagation of Chrysanthemum lavandulifolium,aiming to cultivate high-quality seedlings for chrysanthemum production,a study was conducted using the tender tips of C.lavandulifolium branches.The effects of different seasons and weather conditions on the survival rate and rooting indices of cuttings were investigated.The results indicated that cuttings taken in April had the best performance,with an average survival rate of 99.75%,which was 22.25%and 3.50%higher than those taken in July and September,respectively.The number of adventitious roots for April cuttings was 16.08,which was 85.90%and 22.75%higher than those in July and September,respectively.The root length for April cuttings reached 3.68 cm,which was 55.93%and 15.00%longer than those in July and September,respectively.Additionally,cuttings propagated on rainy days had a 4.50%higher survival rate,32.04%more adventitious roots,and 12.29%longer roots compared to those on sunny days.Therefore,the optimal propagation time for C.lavandulifolium cuttings is on rainy days in April.
