Performance Test and Heat Preservation Measures of Solar Greenhouse in Northwest Rural Area

Solar greenhouse is an important feature of China′s agricultural development system，its energy saving and sunlight temperature control could achieve unmotivated production in winter，has been widely applied in most parts of northeast China，north China and northwest China.An agricultural area in northwest rural area was been taked as an example，combined with performance test of solar greenhouse，heat preservation and light collecting performance of solar greenhouse were analyzed emphatically，and finally some effective measures to improve thermal insulation performance of solar greenhouse in northwest China were put forward.
