摘      要：Two-year-old Medicago sativa at budding initial stage was taken as research *** methods were used to make green hay,including flatting stems ＋ spraying 2.5% K2CO3,flatting stems,sun curing,drying in shade and drying under 105 ℃ condition（CK）.Besides,effects of different green hay making methods on dry characteristics and nutritional quality of *** green hay were studied,and a comprehensive evaluation of *** green hays was *** showed that,except CK,the drying rates in other making methods were all fast at first,and then slow *** of drying under 105 ℃ condition and flatting stems ＋ spraying K2CO3 could speed up drying rate and reduce nutritional losses of green *** curing could also speed up drying rate,but it could not maintain the quality of green *** results of Grey Relational Analysis on five green hay making methods indicated that CK had the best comprehensive performance,followed by green hays made by flatting stems ＋ spraying ***,flatting stems ＋ spraying K2CO3 was a quick and easy method to make green hay,and it was worth to be recommended in practical production.
