Abstract: In order to save the clean water resources for expanding the utilization of reclaimed water and insuring lawn good quality,the effects of reclaimed water irrigation on the distribution of nutrients in plant tissues were studied.The results showed that the distribution of nitrogen,phosphorus,potassium and chloride in turfgrass tissues was similar.Nutrient concentration in leaf was the largest,next was that in stem,nutrient content in root was the smallest.The correlation coefficients were higher for different shoots.The correlation was significant between the nutrient content of leaf and other nutrient content from above-ground organs of turf.It was beneficial to the remobilization of nitrogen,potassium and chloride to above-ground plant irrigated with reclaimed water by comparing fresh water irrigation.With the increase of water supply,the nutrient concentrations of nitrogen,potassium and chloride decreased,while the phosphorus concentration increased.The mutual relationship between turfgrass quality and the content of plant nutrient was analyzed using the method of path analysis.The results showed that potassium content of leaf,chloride content of rhizome,phosphorus content of stem and chloride content of leaf were the main factors influencing the integrated quality of turfgrass.These factors have big direct effects on the integrated quality of turfgrass.
