Abstract: In order to investigate the effects of biological additives on the quality of mixing water hyacinth and maize stalk, four mixture ratios of water hyacinth and maize stalk at 8∶2, 7∶3, 6∶4 and 5∶5 (W8M2, W7M3, W6M4 and W5M5) were designed. In addition, no-additive, fermented green juice (FGJ), cellulase (CEL) and FGJ+CEL (MIX) were added for all materials. After ensiled for 60 days at ambient temperature, the nutritional composition were measured for each treatment. Three kinds of additives significant improved the fermentation quality of water hyacinth and maize straw mixed silages (P<0.05). FGJ and CEL also had obvious interaction. In addition, with the increase of corn straw mixture ratio, the quality of silage was improved. W5M5 was the best silage.
