【Abstract】 The paper reported that the base materials influence cuttage propagation of Rhododendron cv Belgium . Pearl rock is the best base materials in cuttage propagation experiment, while lumus soil and quartz sand are not successful in cuttage propagation experiment. The live rate of cuttage in pearl rock is up to 85%. That can be used in production. Using coordinated soil, Rhododendron cv. Belgium can grow to 20cm high for 1 year.更多还原
