Abstract: In order to characterize the influence of mineralization of irrigation water on yellowing and kraurosis of grape leaves， the Shanshan Oasis in Xinjiang was selected as research area， and the leaf etiolating， browning， kraurosis， and grains falling off in this area were investigated. The collected groundwater samples were analyzed， along with scanning electron microscopy （SEM） analysis of the blade virus to elucidate the reasons for this phenomenon. It was shown that the groundwater and drainage water in this area exhibited relatively high salinity， and the yellowing and kraurosis of grape leaves， and the falling off of grape were all caused by salt injury from groundwater irrigation. Besides salt injury， the grape plants may also be influenced by virus which could cause margin shrinkage of grape leaves， and increase hazard of browning and rolling down. In Shanshan County， one regular irrigating could cause a 1 to 2 grade salt injury， thus, more attention should be paid to this problem.
