坡垒(Hopea hainanensis Merr.et Chun)是海南岛特有的珍贵用材树种。我场于一九六二年从海南岛引入坡垒种子进行试种,经过十多年的生长,现已郁闭成林,有40％的植株开花结实。经花期观察,坡垒在准热带湿润气候的勐旺,长势良好,冬无寒害,抗病虫害力强,且育苗、造林成活率高。一、勐旺的自然条件我场位于西双版纳景洪县北缘,东经101°45′,北纬22°23′,海拔820——1250米,年平均气温20.8℃,最高温达38.4℃,最低温为1.1℃,几乎全年无霜,年降雨量1416毫米,雨日200天左右,雨
Hopea hainanensis Merr.et Chun is a unique species of precious timber for Hainan Island. In 1962, we introduced slope seeds from Hainan Island for trial planting. After more than a decade of development, we have closed forests and 40% of the plants have blossomed. Observed by the flowering period, slope ramp in the quasi-tropical wet climate Meng Wang, good growth, winter cold harm, pest resistance and strong, and nursery, afforestation survival rate. I. The Natural Conditions of Mengwang Our field is located in the north edge of Jinghong County, Xishuangbanna, east longitude 101 ° 45 ’, latitude 22 ° 23’, elevation 820 - 1250 meters, the annual average temperature of 20.8 ℃, the highest temperature of 38.4 ℃, the lowest temperature For 1.1 ℃, almost year-round frost-free, the annual rainfall of 1416 mm, rainy days about 200 days, the rain
