太平地公社位于赤峰市郊区,属于半干旱地区的半川半丘陵类型。年降水量350—400毫米,年蒸发量2000毫米,地下水位约10米;无霜期145天左右。在地势平坦的地段适合于一些杨树的生长。一九六六年营造的林带,主要树种有北京杨、加拿大杨(以下简称加杨)、先锋杨、东风杨和乡土树种小叶杨、白榆等。大部分营造在河川平地,土质较肥,属沙壤土类型。林带为四行或三行组成,造林密度为2×2米。成林后林相整齐,生长旺盛,防护效益较大。几年来,随着林带的生长,我们对几个树种进行了一些调查和分析工作,以便总结营林经验,为
Taiping commune is located in the suburbs of Chifeng, semi-arid area semi-hilly type. Annual rainfall of 350-400 mm, the annual evaporation 2000 mm, groundwater level of about 10 meters; frost-free period 145 days. In the flat areas suitable for some poplar growth. In 1966 to create the forest belt, the main tree species are Beijing Yang, Canada Yang (hereinafter referred to as Yang), pioneer Yang, Dongfeng Yang and native tree poplar, white elm and so on. Mostly created in the river level, soil more fat, is a sandy loam type. The forest belt is composed of four rows or three rows, afforestation density is 2 × 2 meters. After forest forest neat, vigorous growth, greater protection benefits. In recent years, with the growth of forest belts, we conducted some surveys and analyzes on several tree species in order to summarize the experience of silviculture
