从1987～1989年中国草业陕西千阳实验点进行了牧草引种试验研究。参试的豆科牧草为3种6个品种,禾本科牧草为6种。3年的试验结果表明:1)在参试的苜蓿品种中,苏联苜蓿盛花期干草产量最高,为1220.4公斤/亩;新疆苜蓿次之,达1192.1公斤/亩,豆科牧草中以红豆草产量最低。2)禾本科牧草中,西部黑麦草返青早,干草产量达1451.6公斤/亩。此外,无芒萑麦为1123.36公斤/亩;营养成分的化学分析结果表明,禾本科牧草的粗蛋白质含量低于豆科牧草,茎低于叶,与常规情况相符。
From 1987 to 1989, China’s grass industry in Shaanxi Qianyang experimental point of forage introduction test. The tested leguminous forages were 3 species of 6 varieties and 6 species of gramineous pasture. The results of three years showed that: 1) Among the alfalfa cultivars tested, the highest hay yield was 1220.4 kg / mu in the alfalfa bloom stage and 1192.1 kg / mu in Xinjiang, lowest. 2) In pasture, the ryegrass in western China turned green early and hay output reached 1451.6 kg / mu. In addition, there was 1123.36 kg / mu mulberry and the chemical analysis of nutrients showed that the crude protein content of grass was lower than that of leguminous forages and the stems were lower than the leaves, which was consistent with the conventional case.
