Abstract：Using maize hybrid LD818 as material, the phosphorus cycling and the relationship between phosphorus and calcium were studied by sand culture method .The results showed that the maize plant height , stem diameter and leaf area were significantly affected by water stress , which reduced by 5 .37%, 26 .14%and 7.66% respectively compared to that under normal condition .And the dry weight , phosphorus content and phosphorus cycling in each organ were decreased .Treated with water stress for 10 days, the dry weight, phosphorus accumulation in upper leaves and phosphorus transport volume in xylem and phloem accounted for 87.5%, 51.3%, 22.0% and 39.8% respectively of that under normal condition .It indicated that water stress decreased the maize growth , accumulation of dry matter , phosphorus accumulation in each organ and phosphorus transport in xylem and phloem , but enhanced the translocation of phosphorus from middle and low-er leaves to upper leaves .
