本文通过温室盆栽试验方法研究了不同富锌污泥施用方法对水稻生长及其重金属含量的影响。结果表明,污泥施用主要通过增加水稻分蘖来促进水稻生长从而提高产量。污泥的施用显著地提高了水稻茎叶和籽粒中锌的含量。
In this paper, the effects of different zinc-rich sludge application methods on the growth and heavy metal content of rice were studied by greenhouse pot experiment. The results showed that sludge application increased rice yield mainly by increasing rice tillering. Sludge application significantly increased the content of zinc in stems and leaves of rice.
