| 摘 要： | 采用盆栽试验,重点探讨了粉煤灰和煤矸石改良盐碱土对柽柳生长的影响.结果表明:施加15％粉煤灰+15％淤泥改良盐碱土效果明显好于l0％粉煤灰+10％煤矸石+10％淤泥的效果,好于20％粉煤灰的改良效果.基质中加入粉煤灰,对提高柽柳发芽率、缩短枝条发芽时间和提高萌发枝条成活率均具有促进作用.施加粉煤灰改良盐碱土的优劣比例顺...

| Abstract: | By using pot experiment,the paper focuses on the effects of saline-alkali soil,which is improved by adding coal ash and coal gangue,to the growth of tamarisk.The result shows that the improvement effect of saline-alkali soil by adding 15% coal ash and 15% sludge is better than adding 10% coal ash,10% coal gangue and 10% sludge,or adding 20% coal ash.To add coal ash to the matrix plays a driving and positive role to raising the sprout rate,shortening the branch sprout time and improving branches survival rat... |
