【摘要】 近年来河北平原严重缺水,夏玉米作为河北平原主要粮食作物之一,若能找到一种适宜该地区的夏玉米水分生产函数,并用其制定科学的灌溉制度,对于该省的节水农业将有重要意义。本文应用望都实验站连续两年夏玉米的不同灌水处理下对应的产量的试验资料,分别用Blank模型和Jensen模型来拟合夏玉米的ET(耗水量)与Y(产量)的关系。更多还原

【Abstract】 Hebei Plain was short of water extremely in recent years, maize is one of the main crops in the Hebei Plain, if an available water production function can be found , and using it to formulate a rational irrigation schedule will have important significance to saving water agriculture there. This paper analyzes Blank and Jensen models of water production functions by using successive two years data in Wangdu Irrigation Experimental Station, which were measured in different irrigated treatments, to stimulate the relationship of wheat evapotranspiration and wheat yield.更多还原
