Abstract: Through comparing the rooting difference of Erica carnea cutting in different treatments, the rooting law of Erica carnea cutting was revealed, in order to provide theoretical basis for the propagation system of Erica carnea and technical support for production practice. Hormone concentrations, cutting periods, matrix types and cutting positions were investigated in the full-light, automatic-spray and temperature-control greenhouse. Least significant difference (LSD) multiple comparisons and one-way ANOVA were applied to analyze the rooting rate, average root number, average root length and the rooting quality in different treatments. The rooting rates reached 82.43% when the shoot was soaked with 1000 mg/L IBA which had significant effect on rooting rate contrasted with the other two levels (P<0.05); the best composition of matrix for softwood cutting should contain 3 parts of coconut tree branny and one part of pearlite; there were significant differences in the rooting rate, root number, and the root length among different types of cutting positions (P<0.05), while an extremely significant level was observed in rooting quality (P<0.01). The best type of cutting position was semi-lignified branches. The rooting rate was 94.2% in September. The appropriate hormone concentration, matrix type and cutting position, cutting period were proved in this study.
