水杉(Metasequoia glyptostroboides Huet Cheng)生长迅速,树形优美,树干通直,适应性强,病虫害少,是我省平原和城市居民区良好的绿化树种。我园于1951年开始引种水杉,经过二十多年的培育驯化,一般生长良好,据南京林产工业学院1972年对园内100株水杉测算,22年生水杉,平均胸径18.4厘米,平均树高12.5米,单株材积达0.135立方米,在当时的南京地区水杉中生长是居于首位的。以后由于有10多年没有很好管理,现有水杉已明显处于衰退状态。
Metasequoia glyptostroboides Huet Cheng grows rapidly, with beautiful tree shape, straight tree trunk, strong adaptability and few pests and diseases. It is a good afforestation species in the plains and urban residential areas in our province. I Park in 1951 introduced Metasequoia, after more than 20 years of cultivation and acclimation, generally good growth, according to the Nanjing Institute of Forestry in 1972 on the park 100 Metasequoia, 22-year-old Metasequoia, average diameter 18.4 cm, the average tree height 12.5 Rice, single plant volume of 0.135 cubic meters, in the Nanjing area was the growth of Metasequoia living in the first place. Since 10 years have not been well managed, the existing Metasequoia has obviously been in recession.
