Comprehensive evaluation of adaptability of alfalfa in dry desert oasis areas in Southern Xinjiang
This study aimed to screen suitable alfalfa varieties for cultivation in arid desert oasis regions of Southern Xinjiang.Eight alfalfa varieties were selected as experimental materials,and their production performance,nutritional quality,and autumn regeneration rate were evaluated using plot trials.The grey correlation analysis method was employed to comprehensively evaluate the varieties.The results showed that WL358HQ,Saidi-7,and the tourists each show outstanding performance in dry hay yield for each cutting,annual dry hay yield,and plant height for each cutting.Xinjiang Daye had the highest average CP content,while Sadi-7 had the lowest average ADF and NDF contents.WL903 showed the highest average RFV.The overwintering rate of Xinjiang alfalfa was significantly higher than that of other alfalfa varieties except for Muxu 5020(P＜0.05).Autumn regeneration rate from 0 to 28 days exhibited a significant positive correlation with autumn dormancy class(P＜0.05).The comprehensive evaluation results were as follows:Sedi-7＞WL903＞Large-leaved alfalfa in Xinjiang＞Yoke＞WL358HQ＞WL5252HQ＞Crown＞Muxu 5020.The study indicates that considering the water,soil,climate,and management level in southern Xinjiang,it is recommended to plant Sedi-7 and Yoke.
