通过田间试验研究了不同加氧灌溉处理对超级稻农艺性状的影响。结果表明：与常规对照相比，机械加氧和化学加氧处理都可以促进超级稻植株的生长，其中处理A4（每天20：00机械通气1次，每次通气4 min）对促进超级稻苗期株高和根鲜重增长的效果最显著，处理A6（20：00机械通气，每两天1次，每次通气4 min）对促进各生育期根系伸长的效果最明显，处理B1和B2（每半个月化学加氧1次，每次加0．03％双氧水10～20 mL）对促进生育后期根冠比增长的效果最明显。

The effect of different oxygen-adding irrigation treatments on the agronomic traits of super rice was studied through field experiment .The results showed that:as compared with the conventional control , both the treatment of mechanically adding oxy-gen and the treatment of chemically adding oxygen could promote the growth of super rice plants .Among different treatments , the treatment A4(conducting mechanical ventilation at 20:00 for 4 min, once a day) obtained most significantly promotive effects on the plant height and root fresh weight of rice seedlings;the treatment A6(conducting mechanical ventilation at 20:00 for 4 min, once ev-ery two days) had most obviously promotive effect on the elongation of root system of rice at various growth stages ;the treatments B1 and B2(adding 10~20 mL 0.03%hydrogen peroxide every time, once every 15 days) was the most advantageous to the increase in root-shoot ratio of rice at later growth stage .
