造纸废水灌溉对沙漠生态林土壤营养成份的影响

Effects of the Desert Ecological Forest Irrigated by Papermaking Wastewater on Soil Nutrition Element

以草浆造纸废水灌溉沙漠生态林湿地为题,通过对不同灌溉年限以及不同土壤深度的土壤营养成份(有机质、总氮、总磷)进行研究,结果显示:沙漠土壤在造纸废水灌溉条件下,相同灌溉年限的土壤有机质、总氮、总磷含量均随着土壤深度的增加逐渐降低;相同土壤深度的土壤有机质、总氮、总磷含量均随着灌溉年限的增加逐渐增大.

Based on the desert ecological forest irrigated by papermaking wastewater, the soil organic matter, total nitrogen and total phosphorus in different irrigation years and deepness of soil are researched. The result shows that soil organic matter, total nitrogen and total phosphorus decrease gradually with the increased depth of soil in the same irrigation year,while they increase gradually with the increased irrigation years in the same deepness of soil.
