安徽拖拉机厂生产的CP—Y8—1型薄壁镀锌装配式大棚骨架是按全国风雪最大地区的抗风、抗压能力设计的,但各地区的风雪原并非一样大.南疆最大风力8级,且出现次数不多;最大降雪量很少超过15厘米.而CP-Y8-1型大棚占地面积仅半亩,售价却高达4,75O元(托运至大河沿).中国科学院石家庄农业现代化研究所和新疆军区7438工厂生产的同类型大棚售价更高达6,600-8,000元,一次性投资太大,许多单位欲买买不起.我们本着大棚骨架既能抵御南疆的风雪,又能在不增加投资的前提下增大使用面积的原则,从1982年即对CP—Y8-1型大棚骨架进行改装研究,获得了成功.
The CP-Y8-1 thin-walled zinc-plated fabricated shed frame manufactured by Anhui Tractor Factory is designed according to the wind and compressive capacity of the largest area in the world, but the snow blossoms in different areas are not the same. Wind 8, and a small number of occurrences; the maximum snowfall is rarely more than 15 cm. The CP-Y8-1 type of shed covers an area of only half acre, the price is as high as 4,75O yuan (checked to the riverside.) China Shijiazhuang Institute of Agricultural Modernization and the Xinjiang Military Region 7438 factory production of the same type of greenhouse price as high as 6,600-8,000 yuan, one-time investment is too large, many units can not afford to buy. We are in line with the framework of the shed can withstand the southern Xinjiang Wind and snow, but also without increasing the premise of increasing investment in the use of the principle of the area, from 1982 on the CP-Y8-1-type greenhouse skeleton modification study, and achieved success.
