摘要
Abstract
Red Globe grape cultivar was used as material for studying the effect of rainproof cultivation on the light intensity and disease incidence on grape clusters and leaves under shed conditions and in field.Results showed that the leaves infected percentage of Plasmopara viticola Bedese et DE Toni was reduced by 27.5% and the disease index was decreased by 19.55 under rainproof cultivation.It clearly illustrated that the rainproof cultivation has significant effect in controlling disease in-fection on grape leaves.Since the fruit clusters in both growing conditions were all protected in special fruit bags ,the disease injuries on fruit dusters were reasonably very low.Therefore, the effect of rainproof in preventing disease infect on fruit clus-ters was not so great as on leaves,the difference of disease incidence on fruit clusters under two growing conditions was only 1.91 percent.The shelter film had great influence on light penetration.The light intensity under shelter was reduced by 29.45 to 31.37 percent depended on the thickness of the film.关键词
