Abstract: [Objective] The objective of this study was to investigate the effects of two microbial fertilizer (G and Y) on wolfberry's quality and yield.[Method] Randomized block design and grey comprehensive evaluation was used.The medicinal quality and output in each experimental group and their difference was determining and analyzed.[Results] The results indicated that the polysaccharides content reached the maximum value under G-6 000 mL and Y-4 800mL per plant,respectively.The content of carotenoid reached in its highest level under 4 800 mL per plant.And the synergism in group G was slightly better than that in group Y.What's more,the flavonoid content was increased at beginning and then decreased with the increasing amount of G.It showed a generally rising trend after using Y,but it was decreased significantly after using large amount (Y-7 200 mL per plant).The optimal effect for synthesizing betaine was under G-3 600 mL and Y-2 400 mL per plant,respectively.For the grain yield,it went up firstly and declined finally with the adding of content G,by contrast,it was dropped following the decrease of content Y.There is a peak of grain yield when using G-4 800 mL per plant and Y-2 400 mL per plant.[Conclusion] Microbial fertilizer has positive effect on advancing and improving production traits of wolfberry.By using grey comprehensive evaluation to judge the virtues or defect degree of different fertilization measures,it concluded that G-3 600 mL and Y-2 400 mL per plant,evaluation value was 17.675 1 and 16.944 1,respectively.Those two kinds of processing have the highest comprehensive superiority.
