Abstract:
In order to ensure the stability of slope,it is particularly important to reasonably choose the plants and their planting mixture,which can guarantee the quick surface structure and the best effect of water and soil conservation of the vegetation.Taking 11 kinds of woody and herbaceous species as materials,using unicast and mixture comparison test,effect of germination rate,coverage,the number and height of sowing combination were studied.The results showed that germination rate and growing of Caragana korshinskii Kom.,Robinia pseudoacacia L.,Tephrosia,Cupressus funebris Endl.,Coronilla varia L.,and Vitex crownvetch?were poor,and they probably were not suitable for the construction of the Southwest slope vegetation;Crotalaria pallida Ait.,Sophora viciifolia Hance, Indigofera amblyatha,Indigofera pseudotinctoria?and Festuca arundinacea might be more appropriate for the area planted species,and they grew well in this experiment.Higher as the number of trees M2C3(woody species effective germination was 24 plants/m2,herbaceous species sowing rate was 1.5 g/m2) and M3C3(woody species effective germination was 36 plants/m2,herbaceous species sowing rate was 1.5 g/m2) combination treatment under the same community coverage were more reasonable.
