摘　　要：农村河道清淤产生的淤泥体量大、有机质含量高,堆放或填埋处理既影响环境又造成资源浪费,生物质电厂燃烧后产生的草木灰渣,如不进行有效利用会变成新的污染源,成为电厂的负担。如能对其进行基质化利用,可变废为宝。以南粳9108为供试品种,以农村河道清淤河泥和草木灰渣为原料制作水稻育秧基质,探究不同配比育秧基质对秧苗素质的影响。结果表明:利用河泥和灰渣配制育秧基质可行性较强,相比对照,60%河泥+40%灰渣育秧效果最优,秧苗素质高于其余配比基质处理和对照,可用作水稻育秧基质,这为淤泥和灰渣高附加值化农用提供一条可行途径。The mud produced by the dredging of rural rivers has high organic matter content,and the stacking or landfill treatment not only affects the environment but also causes waste of resources.If it can be used as a culture substrate,waste can be turned into treasure.In this study,Nanjing 9108 was used as the test rice variety,and the rice seedling substrate was made from rural river mud and plant ash residue,and the effects of different ratios of seedling substrate on seedling quality were explored.Compared with the control and other treatments,60%river mud+40%ash had the best seedling raising effect,and the seedling quality was higher than that of the other substrate treatments and controls,which could be used as a rice seedling raising substrate,which provided a feasible way for high value-added agricultural use of dredging river mud and plant ash.
