Reed as a key wetland species and people are more and more concerned about it, reed has a lot of advantages characteristics, such as paper raw materials, excellent pasture, soil stabilization whole bayous, wasteland development and so on. Bulid a experimental,study on reed growth dynamics and physiological indicators, it beneficial to the shortage of water resources in improving water resources utilization and reed yield is of great significance. This paper in Panjin City of Liaoning Province Shuangtaizi wetlands reed for the research background,through comparative and analysis the reed growth dynamic parameters and physiological indicators of water production and it proposed fit to reed growth under irrigation water conditions,it can guidance seawater resources use effective and artificial cultivation of reed .First,design of seven different salinity of irrigation water testing,the study reed growth dynamic. It main observation reed growth dynamics,seedling rate,leaf area,dry matter quantity,the number of weeds and irrigation,and other parameters and indicators.Second,study on growth dynamics and physiological characteristics of reed under different irrigation water salinity,it revealed the changes reed growth dynamics of the law in the salinity of irrigation water. Salinity of irrigation water is significantly affected on reed height growth,seedling rate. Proper salinity of the irrigation water can promote growth,increased the growth stage of the reed height,seedling rate and leaf area,high salinity of irrigation water is inhibited the growth of reed.Third,Through analysis various physiological indicators of reeds with salinity of irrigation water,that the changes salinity of irrigation water impact reed dry matter accumulation. Proper salinity of irrigation water can promote reed dry matter accumulation and excessive is not conducive to dry matter accumulation.Fourth,different salinity of irrigation has a significant effect on the growth of weeds,higher salinity at the reed significantly less than the number of freshwater weeds and low salinity of irrigation water,that the high salinity of irrigation water in favor of remove weeds. Fifth,comparative and analysis of different salinity of irrigation water for reed production and consumption of water,it showed that the salinity of 0.3% reed can achieve the objective of saving water and the yield will be better. Therefore,we should choose planting the reeds.
