摘要:

磷(P)对水稻生长的影响仅次于氮。P在土壤中含量丰富,但由于其难溶性及土壤的高吸附性,可被植物直接吸收利用的活性P含量很低。根表铁膜对土壤中的P有很强的吸附作用,在一定程度上是植物的营养库,铁膜中的P是植物吸收的重要P源。有关根表铁膜与水稻P吸收的关系已有很多报道,是促进还是抑制作用情况比较复杂。本文综述了水稻根表铁膜的形成原因、对P的吸附与解吸附能力以及对水稻吸收利用的影响,并对今后开展根表铁膜对水稻P吸收的调控机理研究提出几点建议,同时对根表铁膜调控水稻P吸收的应用前景进行了展望。

Abstract:

The effect of phosphorus (P) on rice growth is next to that of nitrogen. The P content in soil is rich, but the active P which can be directly absorbed and utilized by plants is very low because of its solubility and high adsorption capacity of soil. Root iron plaque has a strong adsorption effect on P in the soil, to some extent, it is the nutrient pool of the plant, and P in iron plaque is an important source of P absorbed by plants. There have been many reports on the relationship between root surface iron membrane and P absorption, but whether it promotes or inhibits P absorption is complicated. In this paper, the cause of iron plaque formation on rice root surface, the adsorption and desorption capacity of P, and the effect of iron plaque on rice P absorption and utilization were reviewed. Some suggestions on the regulation mechanism of iron plaque on rice P absorption were put forward, meanwhile, the application prospects of the iron plaque on the root regulating P uptake in rice were prospected.
