番茄营养液育苗与基质育苗对比试验

为探明营养液育苗和基质育苗对番茄生长发育的影响，对比了2种育苗方式下番茄苗的壮苗指数、坐果情况及产量差异。试验结果表明，采用营养液培育的番茄幼苗地下部更健壮，壮苗指数较高；采用基质穴盘培育的番茄定植后前期长势、结果率、产量更好，但差异并不显著，两者均适宜在集约化育苗场大规模生产应用。

Effects of Raising Seedlings with Nutrient Solution or Substrate on Tomato Growth and Development

In order to investigate the effects of raising seedlings with nutrient solution and substrate on tomato growth and development, this experiment studied differences of sound seedling index, fruit-setting characteristic and yield between them. The results showed that tomato seedlings cultivated in nutrient solution had more robust underground part and higher sound seedling index, while tomato plug seedlings cultivated in substrate grew better in early stage and had higher fruit-setting rate and yield, but the differences were not significant. Therefore both two seedling-raising methods were suitable for large-scale use in the production of intensive vegetable seedling-raising factory.
