Effects of aged wastes from landfill on seed germination of Cucumis sativus L
摘要
Abstract
To properly utilize aged waste resources is an important issue in eco-environmental protection. In this study, 20% , 80% , and 100% of aged wastes from landfill were added to culture medium to investigate their eco-toxieity on the seed germination of Cucumis sativus, with distilled water and soil as the contrasts. The wastes could substantially improve the seed germination of C. sativus, and didn' t show any toxic effect. The optimal proportion of the wastes in the medium was 80%. In this case, the seed germination potential was increased by 12. 8% and 7. 6% , and the seed germination rate was increased by 11.3% and 7.2%, as compared with those in distilled water and soil substrate, respectively. The aged wastes could also promoted the growth of root and sprout markedly. In the medium with 80% of aged wastes, the root length, sprout length, and sprout fresh weight were increased by 177. 6% and 49. 0% , 44. 9% and 28. 4% , and 143.4% and 72.4% , as compared with those in distilled water and soil substrate, respectively. These results suggested that land application of the aged wastes from landfill could be a feasible approach for the recycling of the aged waste resources.关键词
