改良型塑料大棚的设计与建造

Design and Construction of the Improved Plastic Shed

针对塑料大棚冬季不能生产蔬菜,日光温室建造耗资大和建后搬迁困难的问题,设计建造了改良型塑料大棚。改良型塑料大棚是在塑料大棚基础上进行结构和形状的改造,可以延长蔬菜生长周期50~60 d,实现了冬春茬果菜提早定植和叶类蔬菜越冬生产。

By vegetable production is difficult in plastic shed in winter,construction cost of greenhouse is higher and the relocation is difficult, improved plastic shed was designed and constructed. The improved plastic shed was designed on the basis of structure and shape reform in the plastic shed. Improved plastic shed extends the vegetable growing period for 50 to 60 days,the winter-spring fruit and vegetable is ear-ly planted and the winter leaf vegetable is still produced.
