A NEW STRUCTURE PLASTIC-FILM-GREENHOUSE

At the present time in the world, it costs more and more for plant growers to build greenhouses, and the consumption of the greenhouses become more.
It is especially difficult for developing countries which are rich in manpower.
But in short of fund and fuel, even if to adopt the prevailing tunnel film-greenhouse or the double film-air inflated greenhouse.

We have done a successful research on a suspended structure system with twisted wires and anchorages.
The chinese traditional construction that has single stop roof and faces south is adopted by the new structure, and the thermal straw curtains are covered on the roof at night.

The result of the research shows that the plastic-film-greenhouse can save fuel by 24.5% than the large glass-greenhouse with polycurtains; the investment of the greenhouse is used sparing about 35.9% and the transmissivity of total solar radiation increases by 4.11%.

However there is still the problem of fluttering in the wind.
Now we are managing to solve this problem.
