摘要: 选择不同基质及不同部位枝条开展榔榆硬枝扦插繁殖试验,结果表明:不同基质对榔榆硬枝扦插生根率有显著影响,以黄心土基质生根效果最好,生根率达81.67%;不同部位枝条对榔榆硬枝扦插生根率有显著影响,以下部枝条生根效果最好,生根率达83.33%。Abstract: A propagation trial of Ulmus parvifolia jacq using woodened branch cuttings at different branch sections and in various substrates was carried out. The result showed that among the 4 given substrates,the rooting rate in the substrate with yellow soil was the highest, reached 81.67%; different branch sections of woodened branch cuttings have significant effect on rooting rate, low part of branches was the best, the rooting rate was up to 83.33%.
