1978年研究设计了龙园78-2型塑料大棚。1979年春天建成使用。该大棚采用园拱型棚梁,无立柱,自动强制换气,经二年使用看出:造型美观,结构坚固,性能良好。1979年农业部设计院组织的大棚结构考察,作为向生产推广的优良棚结构之一。在1980年黑龙江省农业局组织的大棚结构考察中,已做为优良棚型结构向生产上推广。一、规模和特点龙园78-2型大棚,东西方向(南北延长),南偏西10度,长36米,宽11米,面积396平方米,中高2.8米,边高(垂直)
In 1978, Longyuan 78-2 plastic greenhouse was researched and designed. Built in spring 1979. The greenhouse arched beams, no column, automatic forced ventilation, seen after two years of use: handsome in appearance, solid structure, good performance. In 1979 the Ministry of Agriculture Design Institute organized a study of greenhouse structure, as one of the excellent shed structure to promote the production. In 1980, Heilongjiang Provincial Bureau of Agriculture organized a study of the structure of greenhouses, which had been promoted as an excellent shed-type structure to production. First, the size and characteristics of Long Park 78-2 type of greenhouse, east-west direction (north-south extension), 10 degrees south west, 36 meters long, 11 meters wide, an area of 396 square meters, 2.8 meters high,
