刺槐属温带树种,在我国中、北部广泛种植。1991年首次在广东省大规模引植刺槐,并作为石灰岩山地的绿化优良树种。试验结果表明,刺槐在广东省连州市石灰岩地区石山中、下部生长良好,其根肥大而横向生长,结瘤固N,适应性强,4年龄刺槐生长速度加快,6年龄树高达4～7m。石灰岩山地种植刺槐林可防止水土流失,高温干旱季节可提高土壤蓄水能力,降低地温和空气温度,增加空气湿度。
Robinia is a temperate tree species, widely grown in northern and central China. In 1991 for the first time in Guangdong Province, large-scale introduction of acacia, and as limestone mountain green fine tree species. The results showed that Robinia pseudoacacia grew well in the middle and lower parts of Rock Hill, Limestone area, Lianzhou City, Guangdong Province. The roots of the locusts grew well and grew transversely. The nodules were solidified with N, adaptable. The growth rate of 4-year-old Robinia pseudoacacia was accelerated, . The planting of Robinia pseudoacacia in limestone mountainous areas can prevent water loss and soil erosion. During hot and dry seasons, soil water storage capacity can be increased, ground temperature and air temperature can be decreased, and air humidity can be increased.
