Abstract: To investigate the effects of micro- fertilizer‘Moyun’on physiology and quality of wine grape ‘Cabernet Sauvignon’, 6-year-old wine grape‘Cabernet Sauvignon’was taken as the test material. The results showed that: with the application of micro-fertilizer‘Moyun’, (1) the single-leaf weight increased, the single-leaf thickness and area and the content of chlorophyll increased, which helped the leaves to conduct the photosynthesis; (2) the longitudinal diameter of the grape fruit increased by 2.72 cm, the horizontal diameter increased by 1.22 cm, and the quality increased by 55.32 g; the diameter of fruit grain increased by 0.13 cm, the transverse diameter increased by 0.05 cm, and the 100-grain weight increased by 19.75 g; (3) the total phenol content of grape increased by 3.4 mg/g, the anthocyanin content increased by 3.53 mg/g, the soluble solids content increased by 1.64%, and the tannin content increased by 1.47 mg/g, reducing sugar content increased by 3.14 g/L, tartaric acid content increased by 0.35 g/L. These indicated that‘Moyun’could help the leaves of‘Cabernet Sauvignon’to grow, increase the photosynthesis of the leaves, and improve the grape quality, which could guarantee high yield and high quality of‘Cabernet Sauvignon’.
