通过试验,我们找到了杜鹃扦插生根最佳的二种激素组合:NAA 20ppm,IBA 100ppm 或500ppm。一、材料红花夏鹃:在本院地栽植株上选择向阳、生长健旺、饱满的枝条、剪取顶梢4～6cM 作插穗。二、试验方法选用二因素四种浓度十六个处理[L16(4~2)]的正交设计。如表Ⅰ每处理10穗,浸泡二小时,插于塑网棚 Through the experiment, we found the best two rhizome cuttings rooting hormone combinations: NAA 20ppm, IBA 100ppm or 500ppm. First, the material safflower Xia Juan: planted plants in the hospital to choose sunny, vigorous growth, full of branches, cut the top 4 ~ 6cM cuttings. Second, the test method used two factors four concentrations of sixteen treatment [L16 (4 ~ 2)] orthogonal design. As shown in Table I 10 spike per treatment, soak for two hours, inserted in plastic net shed
