文章编号：1673-887X(2023)06-0186-03秸秆全量还田下冬小麦简化施肥技术研究刘超1，董玲霞2，刘萍英1，耿娟3，刘金萍3（1.徐州市贾汪区农业农村综合服务中心，江苏徐州221011；2.江苏徐淮地区徐州农业科学研究所，江苏徐州221121；3.徐州市贾汪区大吴街道办事处农业农村办公室，江苏徐州221011）摘要分析在前茬水稻秸秆全量还田下，种植小麦应用“生物腐熟菌+普通尿素+控释尿素”简化施肥（一基一追）技术模式对生育期、产量及效益的影响，探讨在“一基一追”的栽培条件下的普通尿素与控释尿素的最佳比例。结果表明，在本试验条件下，普通尿素与控释尿素比例在7∶3的情况下，产量最高达到589.11kg/0.067hm2，比不施肥处理多389.8kg/0.067hm2，比不施用缓释肥处理多4.87kg/0.067hm2。实现了施肥次数减少、基础产量提高和化肥减量增效，促进了耕地质量提升。关键词冬小麦；简化施肥；控释尿素中图分类号S147.3；S512.1文献标志码Adoi:10.3969/j.issn.1673-887X.2023.06.068StudyonSimplifiedFertilizationTechnologyforWinterWheatunderFullStrawReturningLiuChao1,DongLingxia2,LiuPingying1,GengJuan3,LiuJinping3(1.JiawangDistrictAgriculturalandRuralComprehensiveServiceCenter,Xuzhou221011,Jiangsu,China;2.XuzhouInstituteofAgriculturalSciencesinXuhuaiRegion,Xuzhou221121,Jiangsu,China;3.AgriculturalandRuralOfficeofDawuSub-districtOfficeofJiawangDistrict,Xuzhou221011,Jiangsu,China)AbstractAbstract：Thispaperanalyzedtheeffectofthesimplifiedfertilization(onebaseandonetopdressing)technologymodeof"biologi‐calmaturitybacteria+commonurea+controlled-releaseurea"onthegrowthperiod,yieldandbenefitofwheatplantingunderthecon‐ditionoffullreturnofthepreviouscropofricestraw,anddiscussedtheoptimalratioofcommonureaandcontrolled-releaseureaun‐derthecultivationconditionof"onebaseandonetopdressing".Theresultsshowedthatundertheconditionsofthisexperiment,whentheratioofcommonureatocontrolledreleaseureawas7:3,themaximumyieldreached589.11kg/0.067hm2,389.8kgmorethanthetreatmentwithoutfertilization,and4.87kgmorethanthetreatmentwithoutslow-releasefertilizer.Ithasreducedthenumberoffertilizerapplication,improvedthebasicyieldandincreasedtheefficiencyoffertilizerreduction,andprom...
