摘要： 采用浮板毛管法（FCH）栽培系统，进行了营养液充氧与否，与番茄生长发育状况、果实营养品质等方面的试验研究。结果表明：在采用改进FCH进行番茄长季节栽培时，充氧与否对番茄长势、产量没有影响，但对番茄果实的营养品质有一定的影响。营养液中充氧不改变果实中可溶性固形物的含量，但可以降低硝态氮的含量，同时会减小糖酸比。

Abstract: With the system of FCH culture, the experimental study of root-zone oxygen environment has been carried out. The relationship was studied, between oxygen content in nutrition solution with tomato growth condition and fruit nutrient quality. The result showed that with the improvement of FCH, tomato growth and yield had nothing to do with oxygen enrichment in nutrient solution or not. But the nutrient quality of tomato fruit had been affected a little. The oxygen enrichment did not change the content of solubility solid in fruit, but could reduce the content of nitrate nitrogen and the ratio of sugar/ acid.
