Abstract：In order to harvest alfalfa hayat high moisture content，in this study three preservatives（calcium pro pionate，sodium propionate and Sodium diacetate propionate） were added to high moisture content （ 20 % - 2 5 % ） ）alfalfa bales according to the initial antimicrobial tests.Samples were taken at O，3O and 6O days after baling，and the nutritional quality，mold species and quantity were determined.The results showed that after 60 days of storage，C3 treatment （ 0 . 2 % Calcium propionate + 0 . 6 % Sodium propionate + 0 . 2 % Sodium diacetate），C5 （ 0 . 3 % Calcium propionate + 0 . 3 % Sodium propionate + 0 . 3 % Sodium diacetate），and C6 （ 0 . 3 % Calcium propionate + 0 . 3 % Sodium propionate + 0 . 4 % Sodium diacetate）were all effective to inhibit the number and species of mold. With the increase of the storage days，the alfalfa bales treated with C5 and C6 were significantly better than CK （ P < 0 . 0 5 ）in CP（Crude protein），NDF（Neutral detergent fiber）and ADF（Acid detergent fiber）． After 6O days of storage，the C6 treatment group had the best comprehensive value for high moisture alfalfa bales.
