摘    要:为了探讨夏玉米高产高效施肥技术。以‘郑单958’为试验材料,研究了3种不同施肥方式对夏玉米产量、单株叶面积﹑单株叶片数﹑株高﹑叶面积系数及穗部性状等方面的影响。结果表明,处理1(种肥施用量占10%+大喇叭口期施攻穗肥占60%+抽雄吐丝期施攻粒肥30%的施肥方法)能明显提高单株叶面积和叶面积系数﹑增加玉米绿叶叶片数、株高,促进单株籽粒中的干物质积累,提高千粒重,从而使玉米产量增长,比处理2(种肥施用量占10%+大喇叭口期施肥量占90%的施肥方法)增产1155.66 kg/hm2,增产率11.65%,比处理3(大喇叭口期全部N肥100%一次施入的施肥方法)增产1770.84 kg/hm2,增产率19.03%;处理2比处理3增产615.18 kg/hm2,增产率6.61%。为了获得夏玉米高产和提高常规氮肥增产效果,采取分期追施,增产显著且高效。

Abstract:The aim of this experiment is to study the technology with applying high quality and fertilizer on summer maize.The study was used ' Zhengdan 958 ' as the experimental material.On the basis of this typical plant,it had shown several influences,such as yield of summer maize,single plant leaf area,single plant leaves number,plant height,leaf area index and ear traits that was affected by these three kinds of methodologies on different fertilizers.The results revealed that the processing No.1(the seeding ferti...
Keywords:summer maize  fertilizing methods  yield  single plant leaves area  leaves area coefficient
