污水灌溉

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。

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 .

通过相关性分析和主成分分析得出，污水灌溉是导致土壤中Cu、Zn、Ni、Cd、Pb积累的重要原因之一。

The correlation analysis and the principal component plot analysis demonstrated that sewage irrigation was the major source of Cu , Zn , Ni , Cd , Pb pollution in the soils .

而土壤-作物系统是农业生态系统的核心，它是农用化学物质施用及污水灌溉等的主要场所，是Cd向人类食物链迁移积累、直接或间接地危害人体健康的关键环节。

As a core of agricultural ecosystem , soil-plant system loads chemicals and sewage , and is the key of transfer of cadmium to food chain .

污水灌溉对浅层地下水已产生一定程度的影响，COD、NO3&N等9项污染物含量均高于清灌区。

The ground water in shallow land is polluted , The contents of nine kinds pollutions-COD 、 NH_3-N et al . are higher than clean water irrigation area 's.

方法调查了90名居住在含镉污水灌溉区30年以上的居民尿中尿镉、尿CdMT和尿肌酐的变化。

Methods The urinary samples of 90 residents having lived in a cadmium polluted area for more than 30 years were collected . The contents of urinary cadmium , Cd MT and creatinine were determined .

污水灌溉对于缓解水资源紧缺地区的农业用水危机起到了举足轻重的作用，同时，污水中含有丰富的N、P等营养成分，提高了农业生产产量。

The waste-water irrigation plays a very important role on the agricultural water crisis which alleviates the short supply of water resource , at the same time , waste-water contains abundant nutritional component such as N , P , etc. , which improves the yields of agricultural production .

通过采样和化学测试，对污水灌溉条件下，小麦、水稻、蚕豆和油菜果实中Cu、Zn、Pb、Cr和Cd的含量及土壤中重金属本底浓度进行测定和分析。

The content of Cu , Zn , Pb , Cr and Cd in wheat , paddy , horsebean and rape , and the background concentrations of heavy metals in soil were measured and analyzed through sampling and chemical test in this paper .

由于工业污染、污水灌溉、污泥施用以及施肥等原因，我国农田土壤Cd污染问题日趋严重，对我国的食物安全和生态安全构成了严重的挑战。

Cd pollution of croplands of China has been shown intensified due to the increasing Cd loading from industrial contamination , sewage water irrigation , application of sewage sludge and Cd-containing fertilizers , which poses critical challenge for food security and ecological safety of China .
