摘　　要：以温室基质栽培番茄为研究对象,观测了番茄的生长发育进程和营养素含量变化,发现在幼苗营养生长阶段叶片营养素含量呈增长趋势,到移植60 d前后达到最大值,从结果期开始叶绿素含量呈下降趋势。研究结果表明,番茄营养诊断的最佳时期为结果期前后,此时也是番茄生殖生长旺盛的时期,其营养水平直接影响最终产量。The growth process and nutrients content changes of greenhouse tomato were observed continuously in its whole life cycle. It was found that nutrients content of tomato leaf was increasing continuously to the maximum at 60 days after the transplantation. The nutrients content would decrease after fruiting stage. The results showed that fruiting stage was the optimal period for estimation nutrients status of tomato ,and its nutrient level would directly affect the final production.
