摘　　要：为给小麦高产优质栽培和高产育种提供理论依据,以云麦53为材料,于2011 ～2012年度在云南3个生态试验点研究了氮磷钾肥施用方式对小麦产量和农艺性状的影响.结果表明,除易门点产量和千粒重外,磷钾肥不同施用方式在各生态点对小麦产量、产量构成因素、株高及穗长等性状影响差异未达显著水平.除弥勒点穗长外,氮肥不同施用方式在各生态点对小麦产量、产量构成因素、株高及穗长有显著或极显著影响.考虑产量因素,本试验云麦53在云南地区选择适量磷钾肥施用时,采用N种＋分＋拔施用方式可实现高产或超高产.In order to provide a theoretical basis for high yield and quality of wheat cultivation and breeding,effects of N,P and K fertilizerapplication patterns on yield and agronomic trait of wheat cultivar Yunmai 53 were studied among 2011 and 2012 in different ecological sitesof Yunnan.The results showed that yidd,yield composition factors,plant height and spike length of wheat had no difference between thetreatments with applying P and K ferilizer application patterns in different ecological sites,except yield and thousand-gnain weight in yimensite.Yield,yield composition factors,plant height and spike length fo wheat had significant or highly signtficant differnce between thetreatments with applying nitrogen application patterns in diffment ecological sites,except spike length in Mile site.According to this study,the high and super-high yield oc Yunmai 53 could be acquired when the application amount of P and K fertilizer were rational and the pattem1of Nsae＋Tilling＋Jointiong was applied in Yunnan.
