堆肥污泥辅助金矿尾矿适生植物筛选的初步研究
Screening of Pioneer Plants for Gold Tailings Amended With Composted Sewage Sludge
摘要
Abstract
Screening of appropriate species of pioneer plants is crucial to phytoremediation of gold tailings. In order to screen suitable species of pioneer plants for gold mine tailings,eleven species of plants,including leguminous,gramineous and ornamental plants,were selected for the test. In the test, composted sewage sludge was amended in the field of gold tailings to assist the plants in setting-up and growing and then its effects on growth of the plants and changes in content of available nutrients in the field were monitored. Results show that among the 11 species of plants tested, erect milkvetch (Astragalus adsurgens),ryegrass(Lollum multiflorum),tall fescue(Festuca arundinacea)and sedum spectabile(Sedum spectabile)were found higher in emergence rate and survival rate,better in growth and larger in biomass,so the four spe-cies of plants could be used as pioneer plants for phytoremediation of fields of mine tailings. Besides,applying composted sewage sludge was beneficial to plant growth,accumulation of plant biomass and supply of available nutrient,but did have certain inhibitive effect on emergence of plant seedlings.关键词
