Abstract:

There is a low content of solubility phosphorus or easily exchange state phosphorus in the calcareous soils because of the high concentration of calcium ion and the low soil moisture. Therefore, the plants living on this soil always suffer from the phosphorus stress. The author summed up the controllable factors and adaptability mechanisms of the plants which growing and developing in calcareous soil, mainly from a view of the nutrient elements. There is a focus on discussion and review of the root system aberrance, root system secretion, and the mycorrhizal fungi infection in root system when the plants live in the condition of phosphorus stress. Furthermore, this paper had a brief review on the problem in correlative studies, and the study trends of this field were also prospected.
