Abstract:

In order to improve the performance of greenhouse, the location of heat protection blanket was changed. We mainly weld a storage rack in the back slope of the greenhouse, which was used to store heat. Storage at 16.7° was to facilitate the decentralization of heat protection quilt. In so doing, improve the high of heat protection quilt at 40 cm by rolling up a high degree, may also enhance the light intensity in greenhouse in winter. On the other hand improve roof vent about 20 cm height may increase the greenhouse ventilation capacity. At the same time, heat can be stored in the storage without taking off the shelves in the summer. This saved manpower, storage space, reduced wear and tear of heat protection quilt and improved the number of years heat protection quilt used to be, so the greenhouse can save about 18000 yuan in its life time. But there were also disadvantages of the design, stored on the ceiling may increase the ridge of high of greenhouse, which could increase the shadow length about 89 cm back of greenhouse in winter. In this study, we determine the light through the greenhouse, ventilation capacity, financial and material resources to save, to examine the feasibility’s short comings and propose improved solutions.
