选择18种草本植物在江西宁都的花岗岩侵蚀区和德安的第四纪红壤侵蚀区进行了4年的定位试验,通过对出苗率、成活率、平均分蘖数、覆盖度、枯落物的浸水容量、根系鲜重、地上部分生物鲜重、有机质等指标进行观测,并采用层次分析法和模糊数学方法对试验品种进行评价,结果表明:百喜草、糖蜜草、柱花草、宽叶雀稗、棕叶狗尾草、鸡眼草、马唐7种草本植物在花岗岩侵蚀区生长良好;百喜草、画眉草、黑麦草、狗牙根、假俭草、宽叶雀稗和苏丹草7种草本植物在第四纪红壤侵蚀区生长良好。
A total of 18 herbaceous plants were selected for the four-year experiment in the granite erosion area of Ningdu and the Quaternary red soil erosion area of De’an. The effects of emergence rate, survival rate, average tiller number, coverage, The fresh weight of root, the fresh weight of the aboveground part and the organic matter were observed. The analytic hierarchy process (AHP) and fuzzy mathematics were used to evaluate the tested varieties. The results showed that: , 7 plants of Setaria viridis, Corn and Crabgrass grew well in the granite erosion area. Among the seven herbaceous plants, including Bachos, Thrush, Lolium, Bermudagrass, Centipedegrass, Quaternary red soils eroded well.
