中国科学院石家庄农业现代化所于1979、1980年先后从日本引进四种不同规格、型号的农用管式塑料大棚,进行了结构、性能等方面的综合研究和两个生产周期的作物栽培试验。在此基础上,借鉴国外技术的长处,结合我国情况,于1981年研究设了PGP5—1型农用管式单栋塑料大棚,由石家庄建筑机械厂试制,目前已小批量生产投放各地使用。一、结构性能与特点1.结构强度:根据我国华北、华东、西北、东北等应用塑料大棚从事农业生产的大部分地区的气候条件,每年在大棚生产的旺
In 1979 and 1980, Shijiazhuang Agricultural Modernization Institute of Chinese Academy of Sciences introduced four kinds of agricultural plastic tubular sheds of different specifications and models successively from Japan and carried out comprehensive research on structure and performance, and crop cultivation experiments in two production cycles. On this basis, learn from the advantages of foreign technology, combined with our situation, in 1981 set up a PGP5-1 agricultural tube single-storeyed plastic shed by the Shijiazhuang Construction Machinery Factory trial production has been put into operation around the small quantities. First, the structural performance and features 1. Structural strength: According to China’s northern, eastern, north-west, northeast and other places in the use of plastic greenhouses engaged in agricultural production in most parts of the climatic conditions, the annual production in the greenhouses
