酿酒葡萄新品种在丘陵山地生态条件下的栽培表现

Cultivated Characters of the New Variety of Wine Grape on Hilly Lands

为选择出适宜我区丘陵山地发展的优良酿酒葡萄品种，以葡萄品种“野酿2号”、“凌丰”、“桂葡2号”为试材，在桂西北丘陵山地生态条件下，通过对各酿酒葡萄品种的物候期、生长结果性能、抗病性及丰产性进行调查研究。结果表明：“野酿2号”长势强旺，高温多雨季节叶片基本无霜霉病发生，在山地栽培表现生长结实性能较好，产量较高，是适宜丘陵山地、石山地生态栽培的优良品种，生产上要注意预防花穗和果穗病害的发生。“桂葡2号”和“凌丰”在丘陵山地表现长势稍强或中等，生长结果性能好，果实成熟期较早，能实现一年两收栽培，可选择在平地、缓坡地、山脚地人工栽培，生产上要注意在5～7月份高温多雨季节对霜霉病的防治。

Takingthe wine grape varieties ＂YeniangNo.2＂, ＂Lingfeng＂, ＂Guipu No.2＂ growing on the silly lands in Northwestern Guangxi as experimental materials, we carried on an experiment to investigae and study the phenological phase, growth and fruiting perfor- mance, disease resistance and productivity of each variety, so as to select a fine wine grape variety suitable for developing in the silly areas of Guangxi. The results showed that ＂Yeniang No.2＂ with the characteristics of well-grown, good fruiting performance, high yield and no downy mildew is suitable for growing in silly and mountainous areas, should be prevented from diseases damage in flowers and fruits. ＂Guipu No.2＂ and ＂Lingfeng＂ with the characteristics of medium vigor, early maturity and bearing two crops a year is suitable for planting in fiat ground, slope land and foothill, should be prevented from downy mildew occuring in May to July during the hot and rainy season.
