Effects of sowing ratios of Legumes-Grasses mixture on the restoration effect of degraded grassland in Horqin area
This experiment was conducted by setting three levels of Legumes-Grasses Mixture ratios:1∶2,1∶3,and 1∶4,studied the effect of different mixing ratios on turning green date,coverage,height,number of community species,and yield,in order to determine the best mixed planting ratio of legume-grass mixtures for the restoration of natural degraded grassland in this area.The results indicated that the 1∶2 legume-grass mix-ture was the best combination for increasing yield,and considering the improvement of vegetation coverage and the facilitation of restoration of degraded grasslands,the 1∶4 mixture was the optimal sowing combination.
