The cutting experiment of Taxodium ' Zhongshansa 302' was carried out in order to explore the solution to the single tree species in the coastal protective forests, timber forests, and the greening forests for countys, highways and dykes in Jiangsu Province. The 1 ~ 2 - year - old branches of Taxodium ' Zhongshansa 302 ' with higher resistance and superior characters were used as experimental materials, plant ash + garden soil as cutting medium, and 0. 5 mg/L NAA + 0. 5 mg/L IAA as rhizogenic accelerant. Result showed that the rooting rate reached 67% and average seedling height was up to 50. 3 cm by applying the cultivating technique of "keeping warm for three layers". It proves that the cutting and cultivation of Taxodium ' Zhongshansa 302 ' are applicable in those areas where have the similar climate conditions with Yancheng.
