摘　　要：水稻在生长过程中根要进行有氧呼吸,加氧灌溉是根据作物生长中根对氧的需求状况下通氧。试验设计了机械加氧、化学加氧和不加氧3种处理,机械加氧A组又分6个处理小组,化学加氧B组又分3个处理小组。每个处理小组做3个重复试验然后取平均值分析。试验检测了超级稻根系和植株的若干生长农艺性状指标,得出两种加氧灌溉均能显著促进根系和植株的生长。其中机械加氧处理组A4组在实穗粒数上高于常规处理组37.6%,在千粒质量上高于常规处理组7.4%。研究结果为加氧灌溉技术在超级稻栽培上的应用提供了理论依据。In the growing process of rice the roots need aerobic respiration. Oxygenation irrigation means oxygenation in accordance with the demand of crops for oxygen for their growth. This experiment used three treatments：mechanical oxygenation, chemical oxygenation and normal irrigation. The mechanical oxygenation group A was divided into 6 Small series and the chemical oxygenation group B was divided into 3 small series. Each treatment had 3 repeated tests and the mean value was taken for analysis. Some agronomic traits of the roots and the plants of super rice were examined.The result showed： two oxygenation treatments significantly promoted the growth of the roots and the plants.In the mechanical oxygenation group A4 the grain number was 37.6% higher than that of the conventional treatment group, and the thousand-kernel weight was 7.4% higher than that of the conventional treatment group.The study results provide a theoretical basis for the application of oxygenation irrigation to super rice.
