The switchgrass was planted in the soil with 131.25, 162.5, 225, 350, 600 mg/kg Cr, respectively. After 40 days, the plant was sampled and its Cr concentration was measured. The results showed that physiological indices and plant biomass have no significant difference between the control and the treatments with low concentration of Cr (<;350 mg/kg), which indicates that switchgrass has high tolerance to Cr. The concentration of Cr in shoots and roots all increased with the increasing Cr concentration in soil. The highest accumulation of Cr in plants reached 1543.8 mg/pot. For heavy Cr-polluted soil (600 mg/kg), the Cr concentration in roots was 872.5 mg/kg. It implies that the root of switchgrass has great ability to uptake Cr from polluted soil. From above results, It is speculated that switchgrass has great potential for phytoremediation of Cr-polluted soil.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82070385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a field experiments with two irrigation levels and four N application rates (0, 100, 200, 300 kg N/ha per crop) in a wheat-maize double cropping system were conducted from 2000 to 2002. Soil N balance, crop yield and N use efficiency as influenced by the different water and N managements were analyzed. The results showed that crop yield maximized at 200 kg N/ha application rate, and wheat showed a higher N requirement than maize. High soil nitrate-N accumulation occurred at 200 kg N/ha or more N application rates, and showed greater N leaching potential for maize season than wheat season. High soil water level resulted in greater N leaching and deeper depths than the low soil water condition. Based on above results, about 150 kg N/ha for wheat and 100 kg N/ha for maize with low soil water level (60-75% field water capacity) were recommended for obtaining high crop yield, N use efficiency and low N loss to environments. This N application rates were much lower than the current N application rates practiced at local area.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79461538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After winter vegetation such as Potamogeton crispus, Elodea Canadensis and Iris. Sibirica were planted, vegetation development and purification effect was observed continuously. Results show that Potamogeton crispus and Elodea Canadensis survived under very low temperature and the vegetation coverage stood at 50percent, Siberian Iris all survived and issued new leaves. Water purification effect indicates that the average removal rates of nitrogen, phosphorus ammonia and CODCr were 32%, 67%, 55% and 29% respectively with hydraulic loading of 140mm·d-1, and the purification efficiency can be strengthened with gradual development of the vegetation. This study demonstrated that wetland with reasonable winter aquatic plants and species composition can ultimately improve the purification effects of wetlands in north China. In addition, waste heat in urban drainage can provide favorable conditions for winter vegetation in cascaded wetland, so it is feasible to increase appropriate water depth to built submerged vegetation with Potamogeton crispus and Elodea Canadensis.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80491290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
