摘 要:分析了上海实施温室工程,引进国外各种类型温室7年来的实际运行情况,结果认为,荷兰Venlo-型玻璃温室在上海地区适应性较好,是上海地区今后发展的主要方向,并根据两种类型温室运行特点,结合上海地区的气候和蔬菜市场特点作了分析。建议在消化、吸收荷兰Venlo-型温室优点的基础上,增加夏天降温设施,改善其夏天降温效果,使之成为上海及周边地区今后发展的主要大型温室设施类型。The 7-year operations of the imported modern greenhouse of Shanghai were discussed in this paper, the Dutch Venlo-type glasshouse and the Israeli-type plastic greenhouse were fully compared in greenhouse investment including vegetable production, greenhouse operation economic profit, the light transmission, the heating effectiveness in the winter, the greenhouse environment control result and the temperature-decreasing effect in the summer time. According to the characteristic of the climate and vegetable market of Shanghai,it was found that the Dutch Venlo-type glasshouse behave much better than the Israeli-type plastic greenhouse, and it will be the main greenhouse type to be developed in the future in Shanghai and surrounding areas. It was suggested that temperature-decreasing facilities should be increased to improve the temperature-decreasing effect in the summer of the glasshouse, and this will help to further develope modern protected horticulture in Shanghai and surrounding areas.
