摘　　要：通过对乌兰县紫花苜蓿三年不同刈割时期饲草产量和营养成分测定,结果表明:第1茬在初花期和第2茬在现蕾期刈割时,鲜草产量分别达到3.81×10^(4)kg/hm^(2)、3.76×10^(4)kg/hm^(2)和3.93×10^(4)kg/hm^(2)。连续三年的品质在初花期均达到一级草标准,现蕾期均达到特级草标准。By measuring the forage yield and nutrient composition of purple alfalfa in Wulan County during different harvest time for three years,the results showed that the fresh grass yield of the first crop during the initial flowering period and the second crop during the budding period reached 3.81×10^(4)kg/hm^(2)、3.76×10^(4)kg/hm^(2) and 3.93×10^(4)kg/hm^(2).For three consecutive years,the quality reached the first grade grass standard at the initial flowering stage and the extra grade grass standard at the emerging bud stage.
