甘肃省沿黄河两岸高扬程电力提水灌区发展日光温室所面临的最大问题 ,就是冬季电力提灌泵站停运 ,日光温室生产无水源保障 ;其次 ,甘肃省沿黄河两岸高扬程提水灌区均为黄土台塬坡地 ,由于黄土的强透水性和湿陷性 ,使这里修建钢筋混凝土蓄水池的造价很高。为了充分开发黄土台塬坡地日光温室的生产潜力 ,试验设计了一种日光温室柔性蓄水池 ,储水量大 ,防渗性能好 ,水面蒸发损失小 ,冬季能保证日光温室作物所要求的水温 ,而且工程造价比刚性的钢筋混凝土水池低 ,很适合在干旱缺水的寒冷地区以及强透水性土壤、沙漠地区贮存水源 ,发展冬季温室生产。
In Gansu Province, the biggest problem facing the development of solar greenhouses in the high-lift power lift water-raising irrigation areas along the Yellow River in Gansu Province is the shutdown of winter power pumping irrigation stations and the protection of water sources in solar greenhouse. Secondly, the high-lift irrigation areas along the Yellow River in Gansu Province are Loess plateau slope, due to the strong permeability and collapsible loess, so here to build reinforced concrete tanks at a high cost. In order to fully exploit the production potential of solar greenhouse on the slope terrace of loess plateau, a solar greenhouse flexible reservoir was designed and tested, which has large water storage capacity, good impermeability and low water evaporation loss. In winter, the water temperature required by solar greenhouse can be guaranteed, And the construction cost lower than the rigid reinforced concrete pool, it is suitable for storage of water in cold and drought-stricken areas and strong pervious soil, desert areas, the development of winter greenhouse production.
