摘　　要：为减少化肥施用量,探寻有机肥对土壤的改良作用和对高丹草产量的影响,以化肥、普通有机肥、有机无机混合肥为材料,开展高丹草的肥效试验。结果表明,综合配施有机肥或有机无机混合肥可提高土壤有机质、全氮、有效磷、速效钾和碱解氮含量,改良土壤理化环境,提高土壤肥力并增加高丹草产量,适合推广有机无机混合肥施肥模式。In order to reduce the amount of chemical fertilizer used and explore the effect of organic fertilizer on soil improvement and yield of sorghum-sudangrass,the fertilizer efficiency test of sorghum-sudangrass was carried out with chemical fertilizer,common organic fertilizer and organic inorganic mixture.The results showed that the combined application of organic fertilizer or organic inorganic fertilizer could increase the contents of soil organic matter,total nitrogen,available phosphorus,available potassium and alkali-hydrolyzed nitrogen,improve the soil physical and chemical environment,improve soil fertility and increase the yield of sorghum-sudangrass.
