世界上一些发达国家,如美国、荷兰、日本、以色列等利用现代大型温室进行园艺作物的研究和生产相当普遍。有些国家设施栽培面积达80%,这是由于设施园艺能够创造和改善作物生长环境,使原有条件下不能生长和生长不良的作物在设施内能正常生长并能提高产量和品质,实现全年供应,提高经济和社会效益。随着我国农业产业结构的调整,设施园艺已成为优化结构、增加农民收入的有效手段。上海、沈阳、北京等大城市纷纷引入国外大型设施,率先建成了中国特色的日光温室,连栋大棚、塑料大棚等也纷纷建成,设施栽培面积迅速扩大。据初步统计,截至1997年,全国设施面积
Some developed countries in the world, such as the United States, the Netherlands, Japan and Israel, are quite common in the research and production of horticultural crops using modern large greenhouses. In some countries, the area under cultivation is up to 80% due to the ability of facilities and horticulture to create and improve the crop growth environment so that previously unworkable and poorly-grown crops can grow normally within facilities and increase yields and quality, Supply, improve economic and social benefits. With the adjustment of China’s agricultural industrial structure, the facilities and gardening have become effective means to optimize the structure and increase the income of farmers. Shanghai, Shenyang, Beijing and other major cities have introduced large-scale foreign facilities, took the lead in building a greenhouse with Chinese characteristics, greenhouses, plastic sheds, etc. have also been completed, the rapid expansion of facilities cultivation area. According to preliminary statistics, as of 1997, the national facility area
