酿酒山葡萄品种区域化的研究

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。
