摘要:
为研究造纸废水灌溉对轻度盐碱退化芦苇湿地土壤改良效应的影响，通过设置不同废水灌溉次数下的随机分组实验，分析不同灌溉次数下芦苇湿地土壤理化性质及酶活性的参数变化。结果表明：（1）随着造纸废水灌溉次数的增加，土壤容重有下降趋势，土壤持水量、总孔隙度则呈上升趋势；土壤pH呈显著下降趋势，含盐量则表现为先下降后增加；（2）土壤速效N、速效P、速效K含量随着造纸废水灌溉次数的增加呈显著上升趋势，分别比CK增加19.73%～73.42%，14.32%～73%，12.49%～60.6%，4次灌溉后上升趋势有所减缓；（3）随着造纸废水灌溉次数的增加，土壤脱氢酶显著增加，比CK高出1.4～2.8倍，而磷酸酶和脲酶分别高出1.3～2.0倍，1.7～2.6倍，并在4次灌溉后增加趋势减缓；（4）土壤微生物量碳含量随着造纸废水灌溉次数的增加呈现上升趋势，比CK增加了0.15～1倍。该研究结果为黄河三角洲盐碱湿地造纸废水合理灌溉提供了试验依据。
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.
