中文摘要	为获得在河西走廊灌漠土日光温室滴灌栽培条件下的黄瓜水肥优化利用模型,以’津优30号’黄瓜为试验材料,采用四因素二次回归通用旋转组合设计,建立了黄瓜产量的水肥耦合模型:Y = 204.44+7.75X_1 +6.84X_2 +4.84X_3 +5.33X_4-3.77X_(12)-3.43X_(22) -10.01X_(32) -4.76X_(42) +2.55X_1X_2-3.43X_1X_3 +_ 2.68X_1X_4 +1.87X_2X_3 +2.37X_2X_4 -10.79X_3X_4.结果表明:在灌水量、尿素、过磷酸钙、硫酸钾优化的水肥用量分别为6 675.0 m~3/hm~2、525.0 kg/hm~2、630.0 kg/hm~2和480.0 kg/hm~2时,黄瓜产量最高,可达212.58 t/hm~2,同时施肥成本、施肥利润、肥料投资效率也最高,分别为0.80万元/hm~2、3.63万元/hm~2和4.54.
英文摘要	In order to obtain the irrigation-fertilization optimization model on cucumber under drip irrigation in the greenhouse with irrigated desert soil in the Hexi Corridor,the cucumber cultivar ’Jinyou No.30’was using as tested material,and using four factors quadratic regression general rotation design,the water-fertilizer coupling model on cucumber production was established as follow:Y=204.44+7.75X_1+6.84X_2+4.84X_3+5.33X_4-3.77X_(12)-3.43X_(22) -10.01X_(32) -4.76X_(42) + 2.55X_1X_2-3.43X_1X_3+2.68X_1X_4 + 1.87X_2X_3 + 2.37X_2X_4 -10.79X_3X_4.The results showed that when the irrigation amount,urea,superphosphate and potassium optimized water and fertilizer amounts were 6 675.0 m~3/hm~2,525.0 kg/hm~2,630.0 kg/hm~2 and 480.0 kg/hm~2,the cucumber yield reached to 212.58 t/hm~2,at the same time,the cost of fertilizer,fertilizer profits,fertilizer investment efficiency were the highest,which were 8 000 yuan/hm~2,36 300 yuan/hm~2 and 4.54,respectively.
