冬暖大棚(日光温室)是山东蔬菜保护栽培的主要设施形式。自80年代以来,经过广大科技人员和菜农的不断探索实践,在棚型结构、采光保温性能及配套技术等方面积累了丰富的经验。在不加温的条件下越冬茬栽培黄瓜成功的基础上,又在西葫芦、番茄、青椒、茄子、草莓等喜温性蔬菜的越冬茬栽培技术方面取得突破,大大丰富了冬暖大棚越冬茬蔬菜的种类。由于冬暖型大棚经济效益显著高于其它类型的大棚,因而发展十分迅速。据统计,1997年山东冬暖大棚面积达150万亩,占保护地蔬
Winter warm greenhouse (greenhouse) is the main form of vegetable cultivation and conservation in Shandong. Since the 1980s, after continuous exploration and practice by a large number of scientific and technical personnel and vegetable farmers, we have accumulated rich experience in shed structure, lighting insulation performance and supporting technologies. On the basis of the success of overwintering crop cucumbers without warming, we achieved breakthroughs in the overwintering cultivation techniques of zucchini, tomato, green pepper, eggplant, strawberry and other thermophilic vegetables, which greatly enriched the winter winter vegetables kind of. Due to the economic benefits of warm-type greenhouse was significantly higher than other types of greenhouses, and thus developed rapidly. According to statistics, Shandong winter warm shed area of 150 mu, accounting for the protection of vegetables
