Water management affects belowground oxidizing activity and decreases cadmium uptake in a low-cadmium rice cultivar, but enhances it in a high-cadmium cultivar under intercropping

The data are useful to study on belowground oxidizing activity and iron plaque formation with respect to Cd concentration in intercropped rice organs in the flooded system and a low ditch and raised bed cultivating system. The data can benefit ecology and agriculture research. These data also can be used to analyze the Cd accumulation and total removal of heavy metals in different cultivating systems and explore the reason that how the low-Cd rice cultivar shared belowground oxidizing activity with neighboring high-Cd rice cultivar under flooded condition, and how a rice cultivar cropped in a raised bed affects the belowground oxidizing activity of the neighboring rice cultivar cropped in a low ditch in a low ditch and raised bed system in monoculture and intercropping systems.

本数据集对于研究在淹灌系统中间作水稻器官的地下氧化活性以及镉浓度与铁质沉积形成之间的关系具有重要价值。该数据集有助于生态与农业研究的深入。此外，数据集亦可用于分析不同栽培系统中镉的积累及重金属的总体去除情况，并探讨低镉水稻品种在淹灌条件下如何与邻近的高镉水稻品种共享地下氧化活性，以及单作与间作系统中，种植于高畦的水稻品种如何影响种植于低畦的邻近水稻品种的地下氧化活性之原因。
