摘要
用多菌灵与福美双按有效成分1：1的比例配制成混剂（简称多·福），并稀释成浓度为300～3000mg／L的10种溶液，分别浸泡变叶术插穗后进行扦插试验。结果表明：在不同浓度处理中，插穗的生根数、根长、根径和成活率的最高值分别为28．6条、23．8mm、1．58mm和66．67％，与清水对照相比提高了9．6条、7．4mm、0．36mm和46．67％．差异均达极显著水平；在浓度为300～750mg／L范围内，插穗生根数、根长、根径、成活率与处理浓度的关系均呈二次曲线模型（R^2〉0．96）。综合分析结果显示，在浸泡时间为3h的条件下，多·福的最佳处理浓度为596mg／L。
Cutting reproduction experiments of Codiaeum variegatum were conducted by dipped treatment of Carbendazim and Thiram mixture with different concentrations （300-3 000 mg/L）. The results showed that the number, length, diameter and the highest survival rate of cuttings reached 28.6, 23.8 mm, 1,58 mm and 66.67%, respectively which improved 9.6, 7.4 mm, 0,36 mm and 46.67% than the control, respectively. The difference between the best treatments and the control groups of every indexes were significant. The relationship between the indexes and the treatment concentrations from 300-750 mg/L presented Quadratic model （R^2 〉0.96）. The comprehensive analysis showed that the theory optimal concentration was 596mg/L when treated for 3 h.
