摘要
通过北京市高碑店污水小麦栽培试验表明:和清灌比,污灌可使小麦增产7—9％,以灌“冻水”增产幅度最大,灌两次“冻水”产量最高。污灌还可提高小麦营养品质,使麦粒内氨基酸含量显著增加,增加幅度达5—9％,污灌不会对农田和地下水造成污染,粮食中重金属含量远远低于食品卫生标准。
The results of experiments showed that the yield of winter wheat irrigated with sewage water increased by 7-9％ comparing with those of clear-water irrigation. The best increasing range of wheat yield was observed in the plots irrigated in winter. The nutrition quality of the wheat was improved by sewage water irrigation. The increase of amino acids in the wheat grains Was significiant. The increase range was 5-9％. The farmland and ground water were not be polluted by sewage water. The heavy metal contents in grains was much less than that in the Food Hygienic Criteria.
