Abstract: In the arid and semi-arid habitat in Mao County in the upstream of Min River, we have performed a 5 years experiment on Cabernet Sauvignon grape cultivar exploring 8 technological approaches applying the autumn basal fertilizer. The results show that D handling (stripy furrows storing fertilizer and water plus plastic mulching) made phenophase ahead of time, with 9-13 days in germination stage, 9-15 days in new shoot growing stage, 8-10 days in initial flowering stage and 6-9 days in fruit maturation stage. Meanwhile, the yield was 1637 kg/667 m2 with the increasing percentage of 19.66%, the total sugar content was 20.34 g/100 g FW with the increasing percentage of 15.57%, tartaric acid content was 0.592 g/100 g FW with the decreasing percentage of 15.55% and the highest anthocyanin content was 78.32 mg/100 g. E (two cave fertilizer) produced least, with the lowest production of 1321 kg/667 m2 and the lowest total sugar content of 17.30/100 g FW. E and C (stripy furrows storing fertilizer and water and plant grass) produced the highest tartaric acid content, reaching 0.694 and 0.701 g/100 g FW, with no distinct differences in tartaric acid content. Then D and H (two cave storing fertilizer and water plus plastic mulching) produced the lowest tannin content, respectively reaching 0.73 and 0.75 g L-1, with no significant differences in tannin content. Besides, there were no evident effects of other fertilizer application techniques on tannin. There was high vitamin C content among C, D, F (two cave fertilizer and plastic mulching) and H, with no obvious differences.
