Effects Of Irrigation With Reclaimed Water On Plant Growth And Soil Microbial Ecosystem

The pot method is used in this experiment,the reclaimed water of different water quality (second-level water,three-level water) using the Gao Bei Dian sewage treatment factory is carried out on the soybean and maize.Analyse the effects that reclaimed water irrigates to crop's growth and quality,soil character and microorganism, The results show that it's safe to irragate soybean and maize by reclaimed water. And the simulate experiment adopting soil pillar also shows that the increase of microbial number and enzyme activity after irragating six experiment's years. Water culture experiments of seed germination showed that reclaimed water can irragter grazing seed.Potato,maize and paddy should not be iraagated in period of germination. These results will be good reference for estimating the influence of reclaimed water irrigation on crop quality and utilizing the reclaimed water rationally.
