1994~1998年,在干旱、中等湿度和高温、高湿地区,对目前主栽的山葡萄品种左山一、左山二、双丰、双优和双红的区域试验结果表明:在干旱地区生产栽培的山葡萄产量、抗病力和品质明显高于中等湿度和高温、高湿地区。其中:果穗重平均提高4.8%~13.05%,果粒重提高7.8%~19.1%,座果率提高4.28%~11.20%,含糖量提高2.72~3.69度,结果枝率提高4.04%~4.78%,总酸降低0.22%~0.39%,霜霉病害、病情指数降低10.29%和39.11%。两性花品种双红、双优、双丰分别增产7.79%~26.44%,但雌能花品种左山一和左山二在高温、高湿地区表现座果率低,并大幅度减产。酿酒山葡萄在我国最佳栽培生态区是:气候干燥少雨、光照充足、昼夜温差大的地区。
From 1994 to 1998, regional experiments of Zusanli, Zusanli, Shuangfeng, Shuangyou and Shuanghong were conducted in the arid, moderately humid, high temperature and high humid areas. The results showed that in the arid region Cultivation of grape yield, disease resistance and quality were significantly higher than moderate humidity and high temperature, high humidity areas. The average weight of ears increased 4.8% ~ 13.05%, fruit weight increased 7.8% ~ 19.1%, fruit set rate increased 4.28% ~ 11.20%, sugar content increased 2. 72 ~ 3.69 degrees, the results of the branch rate increased 4.04% ~ 4.78%, total acid decreased 0.22% ~ 0.39%, downy mildew disease, disease index decreased 10.29% and 39.11% . The bisexual varieties Shuanghong, Shuangyou and Shuangfeng increased 7.79% ~ 26.44% respectively, but the Zongshan I and Zusanli were lower in high temperature and high humidity area, Cut Winery grapes in our country the best cultivation of ecological zone is: dry climate, adequate sunshine, temperature difference between day and night area.
