摘要
采用生态有机肥与化肥配施的方法,探讨有机-无机肥配施与有机、无机肥单施及不施肥对甘蔗产量和品质的效果,为生态有机肥在甘蔗生产上合理应用提供理论依据。试验结果表明,生态有机肥与化肥配施可显著增加蔗茎产量,比对照增产达1%显著水平,比化肥和生态肥单施增产均达5%显著水平;化肥单施产量略超生态肥单施,但差异不显著。生态肥与化肥配施得到的甘蔗蔗糖分和蔗汁品质不如生态肥单施,好过化肥单施,即处于生态肥和化肥两者之间。生态有机肥与化肥配合使用的地力得到培育,肥料利用率得到提高,甘蔗获得增产,蔗汁品质得到改善,是优良的施肥制度。
A field experiment was carried out to study the effect of combined application of organic-inorganic compound fertilizer, organic fertilizer, inorganic fertilizer and no fertilizer treatments on sugarcane yield and quality, aimed to provide theoretical basis for rational application of ecological organic fertilizer on sugarcane. The results showed that the combined application of ecological organic fertilizer and chemical fertilizer can significantly increase cane yields,which was over control 1%, over chemical fertilizer or ecological organic fertilizer 5%; The chemical fertilizer can increase more cane yields than ecological organic fertilizer,but not significantly. Sucrose content in cane and sugarcane juice quality obtained by combined application of ecological organic fertilizer and chemical fertilizer were between ecological organic fertilizer and chemical fertilizer,that was inferior to ecological organic fertilizer and better than chemical fertilizer. Combined application of ecological organic fertilizer and chemical fertilizer was an excellent fertilization system which can cultivate land capability, improve fertilizer use efficiency,increase cane yields and improve sugarcane juice quality.
