【摘要】 在拟定设施农业种植模式的基础上,通过对设施农业不同种植模式全生育期需水量的分析,采用长系列计算方法,应用水量平衡原理,通过对设计灌溉保证率下设施不透水面可集水量及其供需平衡的调节计算,分析确定了补充集流面面积以及与之配套的蓄水设施容积组合,提出了设施农业雨水集蓄经济利用模式[1]。更多还原

【Abstract】 Based on planting patterns study of facility agriculture,water demand is analyzed in different planting patterns during the whole growth period.The amount of collecting water from facility impervious surface and supply-demand balance under designed irrigation guarantee rates are regulated and computed by using long-series method and application of water balance principle.It is determined supplementary catchment area and matching volume of storage facilities,and the economic pattern of rainwater harvesting is put forward for facility agriculture.更多还原
