Its trunk straight, rapid growth, lush foliage, green color, compact structure, the crown was conical (column) shape, is one of the fine landscape trees. However, the city less mother trees, and more in winter, spring big spike cuttings, so the reproductive coefficient is low. In 1984, we carried out Shu cypress big, medium and small spike four season cutting seedling experiment, and now we have achieved good results. First, the election site and the bed experimentally located in Gudong County Zhu blocking rural forestry station, flower garden and residential area hospital.
