| 通过测桶试验,研究了污水、稀释污水、再生水和清水灌溉条件下,冬小麦籽粒中淀粉、蛋白质、氮、磷、钾含量的变化,以及不同水质灌溉对小麦籽粒产量和籽粒中重金属残留的影响。结果表明:当灌水定额相同时,4种不同水质处理,小麦籽粒中粗蛋白质的含量为污水>稀释污水>再生水>清水,且污水中粗蛋白质的含量要明显高于其他水质处理;低灌水定额时,污水、稀释污水和再生水处理与对照相比分别增产12.71%,9.57%和1.14%;高灌水定额时,污水、稀释污水和再生水处理与对照相比分别增产12.22%、5.05%和2.12%。污水、稀释污水和再生水与清水相比,小麦籽粒中的重金属含量无显著差异,其单项污染指数和综合污染指数远小于1,未形成污染。 |
| 英文摘要: |
| Through the barrel experiment,comprehensive studies were conducted on the changes starch,protein,nitrogen,phosphorus,potassium content in wheat grain under the sewage,1/2 sewage+1/2 clean water,reused water and clean water irrigation condition,as well as the influence of irrigation with different quality of water to wheat yield and content of heavy metal residuals in the grain. The results indicate: When the irrigation quantity is the same,the crude protein content in wheat grain in the irrigations with four different kinds of water is sewage >1/2 sewage +1/2 clean water > reused water > clean water,and the crude protein content in sewage irrigation is obviously higher than in other four;With low irrigation quantity,the wheat yield increases by 12.71%,9.57% and 1.14% in the irrigation with the sewage,the dilution sewage and reused water respectively compared with the control;With high irrigation quantity,the wheat yield increases by 12.22%,5.05% and 2.12% in the irrigation with the sewage,the dilution sewage and reused water respectively compared with the control.Compared with clean water irrigation,there is no significant difference in the content of heavy metal residuals in the wheat grain in irrigations with sewage,the dilution sewage and reused water,with its single and comprehensive pollution indexes both far smaller than 1,which cannot form pollution to wheat grain. |
