摘要
为筛选适宜西藏拉萨地区种植的紫花苜蓿(Medicago sativa)品种,本研究于2017-2019年对国外引进的5个紫花苜蓿品种进行品种比较试验,调查越冬率,测定生育期、鲜干草产量和营养成分。结果表明,WL168HQ和WL298HQ的干草产量、粗蛋白含量、越冬率和相对饲喂价值高于其他品种,中性洗涤纤维含量低于其他品种。因此,WL168HQ和WL298HQ适宜在西藏拉萨地区种植。
In order to select Medicago sativa varieties that are suitable for cultivation in Lhasa,Tibet,this study carried out a comparative test on five imported alfalfa varieties in 2017-2019,investigated the winter survival rate,and determined the growth stage,fresh and hay yield and nutrient composition.The results showed that the hay yield,crude protein content,winter survival rate and relative feed value of WL168HQ and WL298HQ were higher than those of other varieties,and the neutral detergent fiber content of WL168HQ and WL298HQ was lower than that of other varieties.Therefore,WL168HQ and WL298HQ are suitable for cultivation in Lhasa,Tibet.
