为解决水稻因根系缺氧而减产的问题，以深优9586为试验材料，采用盆栽试验，通过白天和夜间气泵增氧增加水稻根际土壤的含氧量，探索不同增氧处理下水稻的生长特性。结果表明，各处理均效果明显，增氧有利于水稻分蘖的早发生，光合作用及根系活力增强，A1处理（白天2 d气泵通氧1次）效果最佳，分蘖始期、盛期、终期的分蘖数分别较CK增加27.3%、28.5%和10.8%；分蘖盛期的光合速率较CK提高26.6%，TTC还原强度在分蘖始期、分蘖盛期、分蘖终期分别较CK高23.6%、30.3%和20.9%。较高的分蘖数、光合速率和根系活力有利于水稻后期的生长。

A pot experiment was carried out to solve the problem of a decrease in rice production due to oxygen-poor to rice root sys-tem, with shenyou 9586 as experiment material, through the pump aeration to increase the oxygen content of rice rhizosphere in day and in night. The results showed that two kinds of aerobic treatment had obvious effects, but the daytime pump aeration was more fa-vorable to early tillering, photosynthesis and root activity, and A1 is the best treatment. Compared to CK, the tiller number and TTC re-ductive intensity of A1 treatment at the beginning tillering period, top tillering period and eventual tillering period were increased by 27.3%, 28.5%, 10.8% and 23.6%, 30.3%, 20.9%. The photosynthetic rate of A1 treatment at top tillering period was increased by 26.6%compared with CK. The higher number of tillers, photosynthetic rate and root activity were benefit to the late growth of rice.
