Abstract: An experiment on prompting viticulture in the field was done during Oct., 2001-Aug., 2002.in Panzhihua vineyard. The treating with chemicals and their concentration were 16.7% CaCN2, 0.5%~2.0% H2CN2, 0.5%~2.0% H2CN2 +1.0%Tween80.The treatment on Jan.10 (1.0%H2CN2+ 1.0% tween 80) had the best dormancy breaking efficiency. It advanced ‘Chardonnay’, ‘Gamay’, ‘Merlot’ and ‘Fox’ sprouting by 16, 13, 11, 4 days, maturity periods by 17, 13, 14, 6 days respectively. It also enhanced the bud breaking percentages of the four varieties by 4%, 12%, 17%, 9% respectively, bud’s shoot-forming percentages by 40%, 29%, 37%, 12%, the fruit shoot percentages by 9%, 8%, 28%, 4%, fructification by 7%, 7%, 37%, 3% respectively. But the investigated data showed that the effects of the advancing maturity period were not remarkable by chemical treating.
