摘　　要：试验于2011年4月-10月在黑龙江北大荒农业股份有限公司八五四分公司农业科技研发中心旱田试验站进行。试验采用随机区组设计,设置4个不同施肥配比处理,研究了氮磷钾肥不同施肥配比对大豆产量的影响。结果表明:病毒病、包囊线虫病以及细菌性斑点病这三种细菌病害在不同施肥配比处理下没有发病植株,而灰斑病和霜霉病这两种真菌病害在不同施肥配比处理下的病情指数为1级,病粒率和虫食率均为0,完全籽粒率为99%,说明这4种不同的施肥配比提高了大豆的抗逆性;氮磷钾配施能够显著影响大豆产量,处理3比对照增产9.06%,处理2比对照增产0.51%,处理4比对照减产19.88%。推荐的高产施肥量为:N33.75 kg/hm^(2)、P_(2)O_(5)101.25 kg/hm^(2)、K2O15 kg/hm^(2),比例为N:P_(2)O_(5):K_(2)O=2.25:6.75:1。The test was done in agricultural science and technology R&D center laboratory test station of the eight-five-four branch company of Heilongjiang the Great Northern Wilderness agricultural limited liability company in 2011 April-Octo⁃ber.Trial used a randomized block design,set four different fertilization ratios of the treatment and made a research of the im⁃pact of different nitrogen phosphorus potassium fertilization ratios on soybean yield.The results showed that:virus disease,cyst nematode and bacterial spot of these three bacterial diseases had no incidence of plants in different fertilization ratio,while the disease index of gray leaf spot and downy mildew of the two fungal diseases under different fertilization ratio processing was 1 and the diseased seed rate and feed rate were 0,full grain rate was 99%,indicating that the four different fertilization ratios had increased the resistance of soybean..The NPK fertilizer could influence the yield of soybean significantly,processing 3 in⁃creased by 9.06%than CK,2 increased by 0.51%than CK and the 4 cut by 19.88%comparing with the CK.It was recommend⁃ed that fertilizer amount for high yield was N33.75 kg/hm^(2)、P_(2)O_(5)101.25 kg/hm^(2)、K_(2)O15 kg/hm^(2),the optimum proportion of N:P_(2)O_(5):K_(2)O was 2.25:6.75:1.
