摘要: 针对四川省攀枝花市二半山区肉牛养殖现状及饲草资源利用情况,引进3个青贮玉米品种和4个黑麦草品种,开展“青贮玉米+黑麦草”轮作模式试验研究。结果表明,在参试的4个黑麦草品种中,“绿岛”的鲜草产量和种植效益均最高,分别为12 973.2 kg/667 m~2和5 189.3元/667 m~2;在参试的3个青贮玉米品种中,“YR12”的鲜草产量和种植效益均最高,分别为8 967.4 kg/667 m~2和3 587.0元/667 m~2元;筛选出的最佳轮作品种组合是“绿岛+YR12”,年产鲜草21 940.6 kg/667 m~2,其次是“特高+YR12”,年产鲜草20 762.2 kg/667 m~2。在攀枝花市二半山区海拔1 400~1 600 m区域内推广“青贮玉米+黑麦草”轮作模式,可大幅增加土地单位面积牧草产量,显著提高了土地资源综合利用率。

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.
