| 摘 要： | 通过土培和盆栽试验研究生物质灰渣与土壤混合培养后对土壤性质的改良作用及对油菜苗期生长的影响.结果表明:随灰渣用量的增加,土壤中有效养分含量增加,尤其是速效磷和速效钾增加显著；随灰渣施用量的增加,土壤pH值升高,平均增幅7.78％,趋于中性；在肥料用量低时,灰渣施用量的增加更有利于土壤中速效磷含量的提高,最大增幅可达4....

| Abstract: | Soil culture and pot experiments of bio-ash mixed with soil were employed to investigate the effects of bio-ash on soil properties and the seedling growth of rape.The results showed that the contents of soil effective nutrients increased with the increase of bio-ash application amount.Particularly the contents of available P and K in soil increased significantly.With the increase of ash amount,pH of soil increases and tends to neutral.The average increase is 7.78%.In low level of fertilizer,the increase of ... |
