Abstract: In view of the current status of beef cattle breeding and forage grass resources utilizing in Erbanshan District of Panzhihua City of Sichuan Province, 3 varieties of silage maize and 4 varieties of ryegrass were introduced. The rotation model test of ＂silage maize＋ ryegrass＂ was conducted. In the 4 tested ryegrass varieties, the highest fresh grass yield （ 12 973.2 kg/667 m^2） and best planting benefit （5 189.3 Yuan/667 m2） was observed in ＂Lvdao＂. In the 3 tested silage maize varieties, the highest fresh grass yield （8 967.4 kg/667 m^2） and best planting benefit （3 587.0 Yuan/667 m^2） was observed in ＂YR12＂. The screened optimal rotation combination was ＂Lvdao＋ YR12＂ with annual fresh grass yield of 21 940.6 kg/667 m^2, followed by ＂Tegao＋ YR12＂ with annual fresh grass yield of 20 762.2 kg/667 m^2. The application and extension of the ＂silage maize＋ ryegrass＂ rotation model in areas with altitude of 1 400-1 600 m in Erbanshan District greatly improved the herbage yield in unit land area and comprehensive utilization efficiency of land resources.
