Field experiment was conducted in Yantai wine region to explore the effect of chemical soil amendment on acidic soil，vine growth and the quality of grape and wine.Three levels(0，4500 and 9000 kg/hm²) of soil amendment，from calcined dolomite and potash feldspar in powder，were applied in Cabernet Gernischt vineyard.The result showed that with the increase of soil amendment，soil pH was increased，as well as soil electric conductivity，and the contents of K，Ca and Mg in the 0～20，20～40 cm soil layer were increased by 23.8%～102.7%，with high dosage of soil amendment.Soil amendment treatments had no effect on vine growth，while the treatments increased grape maturity by 10.7% and 9.4%，compared with the control.The contents of phenolic compounds and tannins of wine were elevated significantly by 16.8%，10.4%，7.1%，respectively，with high dosage of soil amendment.The results indicated that the treatment of chemical soil amendment could effectively ameliorate acid soil，and improve fruit maturity and wine quality.
