研究了沼液农用对莴苣重金属含量和产量的影响,结果表明:沼液灌溉会增加莴苣体内重金属铜( Cu )和锌( Zn)的含量,且随着沼液施用量的增加而增加;但只灌溉一个生长季的莴苣中重金属含量低于国家食品卫生标准;与施用常规化肥相比,沼液灌溉能更有效地促进莴苣产量增加。
研究瞭沼液農用對萵苣重金屬含量和產量的影響,結果錶明:沼液灌溉會增加萵苣體內重金屬銅( Cu )和鋅( Zn)的含量,且隨著沼液施用量的增加而增加;但隻灌溉一箇生長季的萵苣中重金屬含量低于國傢食品衛生標準;與施用常規化肥相比,沼液灌溉能更有效地促進萵苣產量增加。

The effects of biogas slurry irrigation on the heavy metal contents and yield of lettuce ( Lactuca sativa L.) were stud-ied.The results indicated that biogas slurry irrigation could increase the contents of Cu and Zn in lettuce plants , which increased with the increase in application rate of biogas slurry;however , the contents of heavy metal in lettuce plants irrigated by biogas slurry in only a growth season were lower than the national standards of food hygiene ; in comparison with the application of conventional chemical fertilizer , biogas slurry irrigation could more effectively promote the yield increase of lettuce .
