With Lanzhou lily as tested material, the influences of development degree of lily bud scale, scale segmentation mode and sterilizing medicament on the cutting propagation rate of lily bud scale were studied.

方法］以兰州百合为试验材料，研究百合鳞片的发育程度、鳞片分割方式和消毒药剂对百合鳞片扦插繁殖率的影响。

Result The results showed that the cutting survival rate and propagation coefficient were higher in interlayer scale, the difference of which was not obvious between outside and inside scales. Compared with integrated scale, cross cutting and score cutting scale all could reduce scale propagation coefficient Treating scale with 0.1% HgCl2 could prevent scale rot effectively and increase propagation coefficient Integrated scale without segmentation was good for lily bud scale cutting.

结果］结果表明：中层鳞片的扦插成活率较高，繁殖系数也较高，外层与内层鳞片之间的差异不明显；与完整鳞片相比，横切鳞片和纵切鳞片都会降低鳞片繁殖系数；用0.1% HgCl2处理鳞片，可有效防止磷片腐烂，提高繁殖系数。
