以贺兰山东麓地区种植和繁育的“赤霞珠”、“蛇龙珠”、“梅鹿辄”等主要酿酒葡萄品种为试材,采用田间调查和实验室测量的方法,研究了宁夏贺兰山东麓地区葡萄树及葡萄种苗卷叶病的发病情况及葡萄卷叶病对葡萄树的影响。结果表明:葡萄树卷叶病平均感病率为4.66%,葡萄卷叶病使得葡萄的产量下降,品质降低,SPAD值和光合速率下降;2012—2014年,宁夏主栽的酿酒葡萄品种种苗卷叶病的带毒率逐年降低。
The main wine grape cultivars such as Cabernet Sauvignon, Cabernet Sauvignon and Merlot, planted and propagated in the eastern foot of Helan Mountain, were used as test materials and field surveys and laboratory measurements , Studied the incidence of grapevine leaf and seedling leafroll disease in eastern foot of Helan Mountain, Ningxia, and the effect of grapevine leaf curl on grapevine. The results showed that the average incidence of grapevine leaf curl disease was 4.66%. Grapevine leaf curd decreased the yield of grape and decreased the SPAD value and photosynthetic rate. From 2012 to 2014, The incidence of leaf curl decreased year by year.
