Abstract：Usingthelarge-fruitedtomatovariety"Provence"astheexperimentalmaterial，thetomatosedlingsweredivided intofourgrowthanddevelopmentstages.Sevencombinationsofnutrientsolutionconcentrationsweresetacordingtothegrowth stagestostudythefectsofnutrientsolutionswithdifrentconcentrationsonthestrongsedingformationoftomatoesintide irigationseedlingraising.Theresultsshowedthatduringtheseedling maturationstage，thestrongsedlingindicesofT6andT7 werethehighest，reachingO.216andO.221respectively，whichweresignificantlyhigherthanthoseofothertreatments.Thenet photosynthetic rates of T3 and T4 were the highest，being 9.68 μmol⋅m-2⋅s-1 and ）.40μmol⋅m-2⋅s-1 respectively，and were significantly higher than that of T7. The root activity of T4 was the highest，reaching 48.49% .The TOPSIS evaluation method wasused tocomprehensivelyevaluatetheindicatorsintreedimensions，namelyphotosyntheticparameters，seedlinggrowthstatus， and root activity. The final evaluation result was T6 > T 4> B ∣> T5 > T1 > T7 > T2.The most suitable combination of nutrient solution concentrationfortomatotideirigationsedlingraisingwasT6（mS/m-1mS/m-2mS/m）.Atthistime，allindicatorsofthe sedlingsweregood，there werenoobviousdiseaseproblems，andthefertilizationamountmetthegrowthneedsof tomato seedlings during the seedling stage.
