The results showed that the material used could strikingly raise water retentiveness and ventilating of medium. Through the determination of the effect of each growth index of several turfgrass, emergence density, plant height, root growth and individual plant′s net primary production were all positively related to the material′s amount mixed, showing that the mixture of material could promote turfgrass growth, further proving that the material used raised medium function of producing carpet turf by life rubbish and made most use of life rubbish resources. It provided a scientific base is for application of environmental engineering by using life rubbish to produce carpet turf. So the study had both important theoretic meaning and applied value.展开更多
用不同种类的基本培养基及不同浓度2,4-D、6-BA,对本地高羊茅的种子进行愈伤诱导.结果表明:基本培养基种类对愈伤诱导无明显的效果;M S培养基下不同浓度2,4-D、6-BA对高羊茅愈伤诱导时间及出愈率差别很大,以9 m g/L效果最佳,愈伤诱导率...用不同种类的基本培养基及不同浓度2,4-D、6-BA,对本地高羊茅的种子进行愈伤诱导.结果表明:基本培养基种类对愈伤诱导无明显的效果;M S培养基下不同浓度2,4-D、6-BA对高羊茅愈伤诱导时间及出愈率差别很大,以9 m g/L效果最佳,愈伤诱导率达70.2%左右;过高浓度2,4-D、6-BA对萌芽和愈伤的形成有负作用;愈伤组织分化以M S-BA 2.0 m g/L-NAA 0.5 m g/L为最佳M S基本培养基,2,4-D浓度以9.0 m g/L为最佳,最适合高羊茅愈伤组织诱导的培养基为M S+9.0 m g/L 2,4-D.展开更多
利用人工模拟降雨装置,结合ICP-MX质谱分析测试技术,深入探讨不同降雨强度、降雨时段和覆盖条件下,粉煤灰草坪基质渗滤特性及其环境效应。研究结果表明:在相同雨强和时段条件下,有草坪覆盖的基质其渗滤液离子浓度和离子流失总量均低于...利用人工模拟降雨装置,结合ICP-MX质谱分析测试技术,深入探讨不同降雨强度、降雨时段和覆盖条件下,粉煤灰草坪基质渗滤特性及其环境效应。研究结果表明:在相同雨强和时段条件下,有草坪覆盖的基质其渗滤液离子浓度和离子流失总量均低于裸露基质。在覆盖状况和时间段相同条件下,降雨强度对覆盖处理中的渗流离子浓度影响不很显著,但在裸露处理中则表现较为明显,雨强为90 mm h-1时大部分离子,尤其是草坪覆盖处理中的离子流失量达最大值。时段对渗漏特性也有一定的影响,总的来说草坪覆盖处理中离子浓度随时段的增加有降低趋势(A l除外);裸露处理中除K、Ca外,其余元素随时段增加浓度呈现增大趋势。此外,所有渗滤液均达到了国家规定的三类水质,部分甚至达到二类水质,不会对人类饮用水造成污染。展开更多
