This study aimed to enhance grain yield under newly developed water-saving rice cultivation, namely 'aerobic rice culture'. While reducing the water input to the paddy field by over 50%, attainable rice yield in aerobic culture was comparable to that in conventional flooded culture(>10t/ha). However, this water-saving cultivation was more likely to induce plant internal water deficit as it considerably restricted the root system development.

本研究旨在提高新开发的节水水稻栽培技术——“有氧水稻栽培”的产量。在减少水田需水量50%以上的情况下，好氧栽培的水稻产量与常规淹水栽培相当（10 ~ 10吨/公顷）。然而，这种节水栽培更容易导致植株内部水分亏缺，严重限制了根系发育。
