针对北方地区冬季鲜菜严重短缺的矛盾,夏县春声蔬菜科研中心于1990年学习东北经验,创造出了当地高效节能日光温室,并配合我们摸索出来的系列高效节能配套技术,在35°N的地区,冬春茬黄瓜完全不加温,实现元月25日上市,6月20日拔秧,亩产量8160公斤,产值1.23万元。番茄亩产量4510公斤,产值7214元。西葫芦3920公斤,产值5120元。为积极有效地推广这项新技术,1991年9月夏县邀请东北三位专家传授技术,现在运城地区已发展到一千余亩。为配合新成果的开发,特总结当地的经验,其关键技术如下:
Aiming at the serious shortage of winter fresh vegetables in northern China, Xiaxian Chunsheng Vegetable Research Center learned the experience of Northeast China in 1990, created a local energy-efficient solar greenhouse, and developed a series of energy efficient supporting technologies that we worked out at 35 ° N Area, winter and spring cucumbers completely without heating, the January 25 listing on January 20, pulling seedlings on June 20, mu production 8,160 kg, the output value of 12,200 yuan. Tomato yield 4510 kilograms per mu, output value 7214 yuan. Zucchini 3920 kg, the output value of 5120 yuan. In order to promote this new technology actively and effectively, in summer of September 1991, three experts from Northeast China invited to teach technology. Now the Yuncheng area has developed to over 1,000 mu. To tie in with the development of new achievements, we summarize the local experience, the key technologies are as follows:
