Therefore, even in a flooded paddy soil, rice roots are actually exposed to a mixed N supply （NH4++ NO-）, although the predominant species of mineral N in bulk soil in paddy rice field is likely to be NH4+.
因此，尽管在淹水条件下，水稻田土体土壤氮素形式以NH4+-N为主，但水稻根际土壤和根表存在着一定数量的NO3-，水稻根系实际上是处于NH4+、NO3-混合营养（又称增NO3-营养）中。

在第三个实验中研究了水稻根表形成的铁膜对水稻吸收和转运汞的影响。
In the third experiment, we investigated the effects of iron plaque on the root surface on mercury uptake by and translocation within rice seedlings grown in nutrient solution in the greenhouse.
结果表明，较高的氮素水平促进根系生长，迅速提高水稻根干重， 但同时降低根冠比。
The result is, high N-level can promote the root to grow, but the root cap ratio will comes down.
在缺铁固体培养基中，可清楚地观察到水稻根表面的分泌物和根的形态变化以及侧根增多。
It was visualized that the secretory materials on the surface of rice roots and root morphological changes including more side roots with phytagel medium added iron-free nutrient solution.
