摘　　要：通过黄瓜盆栽试验,研究了铜基营养保护剂和控释钾肥对其产量、品质及病害防治的影响。结果表明:喷施铜基营养保护剂和施用控释钾肥显著提高了黄瓜产量,改善了黄瓜营养品质,含硼锌的铜基营养保护剂较清水和传统波尔多液的处理分别增产106.73%和19.81%;施用控释钾肥较不施钾肥和施用普通钾肥的处理分别增产26.61%和6.22%,且显著提高了黄瓜生长后期土壤速效钾含量。铜基营养保护剂和控释钾肥对黄瓜产量和营养品质均有显著的交互作用,且喷施铜基营养保护剂对黄瓜植株白粉病具有很好的防治效果,比传统波尔多液处理降低了铜的积累,增加了锌的含量。因此在黄瓜上施用控释钾肥配合叶面喷施铜基营养保护剂,既能满足黄瓜生育期内对钾素的需求,增加黄瓜产量,又在预防植株白粉病的同时,显著改善果实营养品质。A pot experiment was conducted to investigate the effects of copper-based nutrition protective agents（CNP）and controlled release potassium fertilizer on yield,quality and disease control of cucumber.The results indicated that the yield and nutritional quality of cucumber were significantly improved by spraying copper-based nutrition protective agents and applying controlled release potassium fertilizer.Compared with water and traditional Bordeaux mixture,boron-zinc-containing copper-based nutrition protective agent increased the yield of cucumber by 106.73% and 19.81%,respectively.Compared with no potassium fertilizer treatment and common potassium fertilizer treatment,controlled-release potassium fertilizer treatment increased the yield of cucumber by26.61%and 6.22%,respectively,and also significantly increased the content of soil available potassium at later growth stage of cucumber.Copper-based protective agents and controlled release potassium fertilizer had significant interaction on yield and nutritional quality of cucumber.Spraying copper-based nutrition protective agents had a good control effect on cucumber powdery mildew,and compared with traditional Bordeaux mixture,copper-based nutrition protective agents reduced the accumulation of copper while increased zinc content.Therefore,applying controlled release potassium fertilizer combined with foliar spraying of copper-based nutrition protective agents not only met the potassium requirement of cucumber plant in the whole growth period and increased the yield of cucumber,but also promoted the prevention of plant powdery mildew and improved fruit nutritional quality of cucumber at the same time.
