摘要
污水农用对于缓解我国水资源短缺具有重要的现实意义。本研究在两种土壤上,以温室盆栽研究了处理后生活污水灌溉对大白菜和菠菜产量、粗蛋白、Vc等营养品质和养分元素吸收等的影响。结果表明,生活污水对两种蔬菜的生长、品质以及养分吸收没有明显的负面影响,表明经过一定处理后的生活污水具有农用的可能性。可进行较长期的定位试验,研究污水农用的可行性。
Municipal sewage is an important water resource for agriculture. Greenhouse pot experiment was carried out to study the effect of sewage irrigation on the yield, nutrient uptake and quality of Chinese cabbage and spinach. The overall effect of sewage on yield and contents of Vc, crude protein, sugar, and nutrients is not statistically significant, suggesting the applicability of using sewage for irrigation purpose. Long term experiment is suggested to ensure the environmental safety before the sewage irrigation is carried out in a large scale.
