粉煤灰改良土壤
fly ash in soil amelioration
fenme一hu一90}l一ong turong粉煤灰改良土坡(fly ash in 5011 ameliora-tion)粉煤灰是由多种颖粒组成的，包括:碳粒、球形颗粒、蜂窝状顺粒、石英等.粉煤灰中粒径大于。.01 mm的物理性砂粒占85%左右，毛细管孔隙度为“%~85%，视密度为2.。~2.29/cm，，容积密度为。.609/cm，。因此，粉煤灰具有质轻、多砂、多孔、渗透快、吸水性及保温性好、吸附性高等特性。同时，粉煤灰中含有植物所需的多种化学营养元素，因此是一种多功效的土壤改良剂。 扮性土城改良各种猫性土壤都质地猫重、通气透气不良、耕性差，水、肥、气、热不协调，因而影响作物生长。利用粉煤灰的物理特性，适量施人粉煤灰(2 .25~4.5 kg/m，)，可以明显地改良土壤质地。主要是:①降低翁土中猫粒相对含量，改良质地;②减小土壤容重.③增加土壤孔隙度，④提高猫土15 cm土层内的温度;⑤提高土坡含水量和田间持水量;⑥调节土壤三相比(固相:液相:气相);⑦减小土镶膨胀率.提高土壤渗透性，防止土坡流失。粉煤灰对猫性土壤物理性质的显著改善.促进了土壤中徽生物活性，有利于养分转化和保温保墒，使水、肥、气、热走向协调，为作物生长创造良好的土壤环境.同时，粉煤灰中含有的硅、铜、锌、钥、钙、铁、锰、翻、硒等营养微量元素，增加了土壤中这些营养元素的含量，改善了土壤养分状况;施用粉煤灰，还可提高土壤中有效磷含量。实践证明，施用适量粉煤灰对小麦、玉米、水稻、大豆等主要作物皆有显著的增产效果，其中小麦平均增产12.7士5.8%，玉米平均增产20.8士10%。另外，对谷子、甘薯、棉花、蔬菜等作物也有一定的增产效果。同时，施用粉煤灰后长出的粮食中蛋白质含量有所增加。 酸性土壤改良对于酸性猫质土壤，除有上述改良作用外，粉煤灰还可以提高土坡中的pH值，使酸性土壤中性化，有利于作物的生长。 盐化潮土的改良向盐化翁性潮土施用粉煤灰，既可改良潮土的翁性，又可起到降盐作用。 在有效硅较低的土壤中，粉煤灰与腐殖酸结合使用，可以提高土壤中有效硅含量，从而改善作物的生长条件。 粉煤灰中含有一定量的有害元素，如锅、铬、铅、砷、汞、苯并(a)花、放射性元素等，经过大量的研究和实践，在施粉煤灰量4.5 kg/mZ以下时，不会对土壤产生污染.对这些土壤中生长的粮食作物也不会造成污染。但由于煤种的不同，粉煤灰中有害元素含量也各有差别，故在施用粉煤灰时应做试验.
