在桂南红壤种植天草桔橙,分别用煤灰、滤泥、蔗渣做改土材料进行改土试验,每667m2均施用27t的改土材料,结果表明,改土后两年来,用煤灰总产1 635kg,增收400元;用滤泥总产1 274kg,亏损237元;用蔗渣总产1 022kg,亏损280元。同时,使用煤灰改土试验后果实的外观、风味及土壤理化性状的改良均优于滤泥,最差是蔗渣。

To choose coal ash,cane mud and bagasse as soil-improvement materials,an experiment was conducted in red soil of Southern Guangxi（27 T per mu）.The results showed that two years after application,the yield per mu for coal ash reached at 1 635 kg with income increase of 400 Yuan,1 274 kg for cane mud with loss of 237 Yuan and 1 022 kg for bagasse with loss of 280 Yuan.Meanwhile,the improvements in fruit appearance,taste and soil physical chemical characters of coal ash treatment are better than other treatments.The worse result was seen in bagasse treatment.
