生物有机肥对比复合肥在甘蔗生产上的应用

以桂糖97-69 作为供试品种，以利达生物有机肥、普通复合肥为供试肥料，设置等价施肥处理，研究不 同肥料处理对甘蔗农艺性状和工艺品质的影响。结果表明，施用生物有机肥处理的甘蔗株高、成茎率、有效茎数、产 量、纤维分、蔗糖分高于施用复合肥处理，但出苗率、分蘖率、茎径不及施用复合肥处理。说明在促进甘蔗伸长、提高 甘蔗有效茎数、产量及含糖量上，施用生物有机肥比施用普通复合肥具有更显著的效果。

Application of bio-organic fertilizer in sugarcane production contrast of compound fertilizer

With GT97-69 as tested material, using Li-Da bio-organic fertilizer and common fertilizer as tested fertilizer, setting the equivalent fertilizer treatments, effects of different fertilizer treatments on agronomic characters and process quality of sugarcane were studied. Results showed that compared with the treatment of using compound fertilizer, sugarcane applied by bio-organic fertilizer had the higher stem length, stem rate, millable canes, yield and contents of fibre and sucrose, but lower emergence rate, tiller rate and stalk diameter. As the aspects of promoting sugarcane extend, increasing millable canes, yield and the content of sugar, compared to the common fertilizer, application of bio-organic fertilizer had higher significant effect.
