安徽农学通报2023年05期土地·土壤·耕作不同轮作模式对花生生长及产量的影响沈悦刘永惠梁满陈志德沈一*（江苏省农业科学院经济作物研究所，江苏南京210014）摘要轮作是缓解连作障碍和粮油争地矛盾的重要栽培方式，对扩大花生生产面积及可持续发展有重要意义。本研究采用4种不同的轮作方式，连续4年观测了花生的农艺性状、产量性状、土壤肥力等指标，发现采用轮作模式可以一定程度上缓解花生连年种植带来的连作障碍：连作春花生第4年有18.13%的干物质量和15.56%的产量衰退，但轮作处理中花生农艺、产量性状基本稳定；土壤硝态氮、速效钾含量在轮作处理中都有较为显著的提升。虽然春花生生育期较长、在活动积温上更具优势，但轮作模式能获得更为稳定、可持续的产量。关键词花生；轮作模式；农艺性状；产量中图分类号S565文献标识号A文章编号1007-7731（2023）05-0099-05EffectsofDifferentRotationPatternsontheGrowthandProductionofPeanutSHENYueLIUYonghuiLIANGManCHENZhideSHENYi*（InstituteofIndustrialCrops,JiangsuAcademyofAgriculturalSciences,NanjingJiangsu210014）AbstractCroprotationisanimportantcultivationmethodtoalleviatetheobstaclesofcontinuouscroppingandthecontradictionbetweengrainandoilproduction,whichisofgreatsignificancefortheexpansionandsustainabledevelopmentofpeanutproduction.Inthisstudy,fourdifferentrotationmodeswereselected,andtheagronomiccharacters,yieldcharacters,soilfertilityandotherindicatorsofpeanutwereobservedforfourconsecutiveyears.Itwasfoundthattheappropriaterotationmodecanalleviatetheobstaclescausedbycontinuousplantingofpeanut.Inthefourthyearofcontinuouscroppingofspringsowingpeanuts,18.13%ofthedrymatterqualityand15.56%oftheyielddeclined,buttheagronomicandyieldtraitsofpeanutwerebasicallystableintherotationtreatment.Inaddition,thecontentsofsoilnitratenitrogenandavailablepotassiumhavebeensignificantlyimprovedintherotationtreatment.Althoughspringsowingpeanuthaslongergrowthperiodandmoreadvantagesinactiveaccumulatedtemperature,therotationsystemcanobtainmorestableandsustainableoutput.Keywordspeanut;rotationsystem;agronomictrait;yieldtrait轮作是指在一定年限内、同一块地上有顺序地轮换种植不同作物，或者采用不同复种方式的...
