研究了不同育苗方式及不同苗龄定植对番茄生长和产量的影响。结果表明：现蕾时更换大营养钵的大苗较一直在小营养钵中生长的中苗株高、茎粗均明显增大，生长速度加快，同时叶片变大，生长加快，定植前大苗比中苗多生长两片真叶，叶片光合作用、总叶面积、地上部鲜重、根鲜重均显著增加；番茄大苗定植采收期最早，产量最高，中苗次之，小苗定植采收期最晚，且产量最低；大苗定植对番茄提前上市及增加产量有显著效果。

The effects of seedling culture manners and field planting at different seedling ages on tomato growth and yield were studied.The results showed that compared with the middle seedlings which grew all along in small nutrition pots,the big seedlings transplanted to large nutrition pots at the flower-bud-appearing stage had a higher plant height,an obviously larger stem diameter,a higher growth speed and larger leaves.And they grew two more leaves before field planting,significantly increasing in photosynthesis,total leaf area,aerial part fresh weight and root fresh weight.Field planting of big tomato seedlings gained the earliest picking time and the highest yield,field planting of the middle ones came second,and field planting of the small ones was the last in picking time and the lowest in yield.So field planting of the big seedlings had a significant effect on increasing tomato yield and being early available on the market.
