自七十年代中叶引进塑料大棚栽培技术以来,黄瓜就是我市塑料大棚覆盖栽培的主要蔬菜之一。由于78年霜霉病和79年枯萎病大流行,加之栽培管理技术落后,黄瓜的种植面积急剧下降,1980年全市仅有80多亩,产量也很低,1981年平均亩产只有6、7千斤。据此,原西宁市蔬菜研究所于1981年就安排了黄瓜栽培试验,1982年又纳入了省保护地蔬菜栽培技术研究攻关项目。经过四年来的栽培研究实践,已取得预期效果,如1981年单棚1.07亩,平均亩 Since the introduction of plastic greenhouse cultivation techniques in the mid-1970s, cucumber is one of the main vegetables covered by plastic shed in our city. Due to the 78-year downy mildew and the 79-year wilt pandemic, combined with the backward cultivation and management techniques, cucumber acreage dropped sharply. In 1980, the city only had 80 mu and the output was very low. In 1981, the average yield was only 6,7 Thousand pounds. Accordingly, the original Xining City Vegetable Research Institute in 1981 arranged cucumber cultivation trials, in 1982 also included in the provincial protected vegetable cultivation technology research project. After four years of cultivation and research practice, has achieved the desired results, such as single shed in 1981 1.07 acres, the average mu
