摘要
为阐明灌溉水矿化度对葡萄叶片枯萎、干枯的影响,对新疆鄯善县成龄葡萄地的葡萄叶片黄化、褐变干枯、穗粒脱落等现象进行现场勘察,采集地下水样品进行测试,并结合扫描电镜检测病毒分析其原因。结果表明,该地区渠水和井水矿化度均较高;两块地葡萄发生的叶缘、叶尖黄化、焦枯,穗粒脱落等现象主要是由于浇灌地下井水引起的盐害所致。葡萄植株受到盐害时生长势减弱,病毒也会引起葡萄叶缘皱缩、褐变向下卷等加重危害。在鄯善县部分葡萄种植区域,以常规灌溉方式,用地下水灌溉1次就会产生1～2级盐害,应引起重视。
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 a1 to 2 grade salt injury,thus,more attention should be paid to this problem.
