摘    要: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。

关 键 词:沼液  莴苣  重金属  产量

Abstract: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 .
Keywords:Biogas slurry  Lettuce  Heavy metal  Yield
