摘要
城市污泥堆肥作为矮牵牛栽培基质是可行的,按污泥堆肥、田园土5∶5体积比配成的基质种植矮牵牛,其冠幅、主根长、地上部分干重、地下部分干重最高,根冠比最小,花茎最大。
It was feasible that urban sewage sludge compost used as growing media of Petunia hybrida, according to the sludge compost, rural soil 5：5 volume match into the substrate to growing Petunia hybrida, it was the highest that the crown breadth, taproot length, the ground part of the dry weight, underground part dry weight, root-shoot ratio minimum, and the stem was the largest.
