为了增加塑料大棚的牢固性,就要增加大棚内的立柱和棚外压膜设备.这样不仅建棚投资大,而且影响,棚内作业,由于立柱影响,棚内不能悬挂天幕保温。压膜不仅影响棚内光照,而且损伤棚膜。因此,设计建造一种无压膜少立柱塑料大棚是广大菜农的迫切要求。我们从1990年开始研究这项工作截止1992年4月11日(1992年4月11日我市风力3级,阵风9级)证明:我们设计建造的无压膜少立柱拉筋式塑料大棚的性能是可靠的,下面谈谈它的结构和效益。 In order to increase the solidity of the plastic shed, it is necessary to increase the column and the plastic film equipment outside the shed, which not only increases the investment but also affects the operation of the shed. Due to the column effect, the canopy can not be suspended. Film not only affects the greenhouse light, but also damage the greenhouse film. Therefore, the design and construction of a plastic film column without plastic greenhouse is an urgent requirement of the majority of farmers. We started to study the work from 1990 until April 11, 1992 (April 11, 1992, the city wind 3, gust 9) proof: we design and construction of non-pressure film less column reinforced plastic greenhouse Performance is reliable, let’s talk about its structure and effectiveness.
