Effects of Paper-making Wastewater Irrigation on Soil Physiochemical Property of Reed Wetland in Mild Saline-alkali Area
摘要
Abstract
To study the effect of paper-making wastewater irrigation on mild saline-alkali wetland and its improvement,through randomized experiment of setting up different wastewater irrigation frequency,the parameter changes of soil physical and chemical properties and wetland enzyme activity were analyzed under different irrigation frequency.Results show that：（1）With the wastewater irrigation frequency increasing,soil bulk density decreased,soil total porosity and water-holding capacity increased;soil pH decreased remarkably and after the first decrease,soil salt content increased;（2）Available N,P,K increased remarkably after irrigation.Compared with CK,available N,P,K increased by 19.73%～73.42%,14.32%～73%,12.49～60.6%,respectively.The trend of rise slowed after 4 times irrigation;（3） Dehydrogenase activity increased remarkably,more than 1.4～2.8 times of CK.Phosphatase and urease activities increased 1.3～2.0,1.7～2.6 times respectively compared with CK,and got a slow trend of rising after 4 times irrigation;（4） Microbial biomass carbon increased by 0.15 to 1 times compared with CK.The result provides the scientific basis for reasonable irrigation on saline-alkali wetland of Yellow River Delta with papermaking wastewater treatment.These results are also helpful for reasonable recycling and exploiting of papermaking wastewater.关键词
