不同基肥与控释钾肥配合施用对烟草生长及品质的影响的开题报告摘要：烟草作为重要的经济作物，其生长和品质直接影响着烟草产业的发展。在烟草生产中，基肥和控释钾肥的施用是关键因素之一。本研究以烤烟为研究对象，通过不同基肥（有机肥、无机肥、有机无机配施肥）与控释钾肥（壳聚糖包膜控释钾肥、普通控释钾肥）配合施用对烟草生长及品质的影响进行了研究。研究结果表明，与对照组相比，不同基肥与控释钾肥配合施用可以显著提高烟草生长指标和产量；同时，不同配方的肥料组合对烟草的品质指标（如烟叶厚度、含氮量、焦油量等）有不同的影响。此外，壳聚糖包膜控释钾肥与普通控释钾肥在不同配方的肥料组合中的效果也有所不同。关键词：烟草，基肥，控释钾肥，配合施用，品质Abstract:Tobaccoisanimportanteconomiccrop,anditsgrowthandqualitydirectlyaffectthedevelopmentofthetobaccoindustry.Intobaccoproduction,theapplicationofbasefertilizerandcontrolled-releasepotassiumfertilizerisoneofthekeyfactors.Inthisstudy,flue-curedtobaccowasusedastheresearchobject,andtheeffectsofdifferentbasefertilizers(organicfertilizer,inorganicfertilizer,andorganic-inorganiccompoundfertilizer)combinedwithcontrolled-releasepotassiumfertilizers(chitosan-coatedcontrolled-releasepotassiumfertilizerandordinarycontrolled-releasepotassiumfertilizer)ontobaccogrowthandqualitywerestudied.Theresultsshowedthatcomparedwiththecontrolgroup,thecombinationofdifferentbasefertilizersandcontrolled-releasepotassiumfertilizerscansignificantlyimprovetobaccogrowthindicatorsandyield;atthesametime,differentcombinationsoffertilizerformulashavedifferenteffectsontobaccoqualityindicators(suchasleafthickness,nitrogencontent,tarcontent,etc.).Inaddition,theeffectsofchitosan-coatedcontrolled-releasepotassiumfertilizerandordinarycontrolled-releasepotassiumfertilizerindifferentcombinationsoffertilizerformulasarealsodifferent.Keywords:Tobacco,Basefertilizer,Controlled-releasepotassiumfertilizer,Combinedapplication,Quality
