【摘要】 该文旨在分析贵州高寒山区威宁县主要牧草产量和常规营养成分含量的影响。试验测定了每平方米产量和常规营养成分。结果表明，苏特燕麦株高130～156 cm，本地燕麦株高110～130 cm，引进苏特燕麦平均株高高于本地燕麦；苏特燕麦刈割鲜草产量分别达3.80、4.92、7.07 kg/m~2，本地燕麦分别达3.37、3.03、4.37 kg/m~2，黑麦分别达2.18、2.16、2.10 kg/m~2。引进品种苏特综合性状表现优于本地燕麦和黑麦草，说明苏特燕麦可在高寒山区威宁县示范推广。更多还原

【Abstract】 This paper aims to analyze the influence on the yield and conventional nutrient content of the main forage grasses in the high-altitude cold area of Weining County,Guizhou Province.The experiment measured the yield per mu and conventional nutrient content of the main forage grasses planted in the high-altitude cold area of Weining County,Guizhou Province,including local oat,ryegrass and introduced Sute oat,at the same period of mowing.The results showed that the plant height of Sute oat was 130～156 cm;the plant height of local oat was 110～130 cm,and the average plant height of introduced Sute oat was higher than that of local oat.The fresh grass yield of Sute oat was 3.80 kg/m~2,4.92 kg/m~2 and 7.07 kg/m~2 respectively;the fresh grass yield was 3.37 kg/m~2,3.03 kg/m~2 and 4.37 kg/m~2 respectively;the fresh grass yield was 2.18 kg/m~2,2.16 kg/m~2 and 2.10 kg/m~2 respectively.The comprehensive performance of the introduced variety Sute was better than that of local oat and ryegrass,indicating that Sute oat can be demonstrated and promoted in the high-altitude cold area of Weining County.更多还原
