Cereal–legume intercropping systems are an environmentally friendly practice in sustainable agriculture. However, research on the interspecific interaction of nitrogen (N) between rice and aquatic legumes has rarely been undertaken. To address this issue, a pot experiment was conducted to investigate N utilization and the N interaction between rice and water mimosa (Neptunia oleracea Lour.) in an intercropping system. The root barrier patterns consisted of solid barrier (SB), mesh barrier (MB), and no barrier (NB) treatments. The N fertilizer application rates were low, medium, and high N rates.

水含羞草 (Neptunia oleracea Lour.) 可以在其间作系统中固定和转移氮到水稻

谷物-豆类间作系统是可持续农业中的一种环保做法。然而，很少对水稻和水生豆类之间氮 (N) 的种间相互作用进行研究。为了解决这个问题，进行了盆栽试验以研究间作系统中氮的利用和水稻与水含羞草 ( Neptunia oleracea Lour.)之间的氮相互作用。根部屏障模式由固体屏障（SB）、网状屏障（MB）和无屏障（NB）处理组成。施氮肥分为低、中、高施氮量。
