| 【目的】化学肥料减量施用技术是避免过量施肥带来环境污染，促进农业可持续发展的重要技术。
探讨有机肥替代化学肥料，为广东冬作马铃薯的商品有机肥部分替代化肥，实现化肥减量提供科学依据。【方
法】以费乌瑞它为试验材料，研究 3 种商品有机肥处理和等施肥量的化肥处理对广东冬作马铃薯产量、经济效益、
肥料表观利用率和品质的影响。【结果】有机肥处理马铃薯块茎对品质的影响与化肥处理无显著差异。3 种有机
肥处理中商品有机肥 2 处理总产量、商品薯产量和总产值高于另外两种有机肥处理，而肥料成本低于另外两种
有机肥处理。商品有机肥 2 处理肥料表观利用率为 10.17%，分别比商品有机肥 1 和商品有机肥 3 处理高 1.96、3.52
个百分点。产量和经济效益占优势的商品有机肥 2 处理有机肥同效当量为 66.02%。【结论】在南方冬作马铃薯
种植中有机肥可以部分替代化肥，实现化肥减施。 |

| 【Objective】The technology of chemical fertilizer application reduction is an important way to avoid
environmental pollution caused by excessive fertilization and promote the sustainable development of agriculture. This study
was conducted to explore the replacement of chemical fertilizer with organic fertilizer, and provide scientific basis for the
application of commercial organic fertilizers in winter potato by replacing chemical fertilizers.【Method】With Favorita as
experimental material, the effects of three commercial organic fertilizers and chemical fertilizer treatments on yield, economic
benefit, apparent fertilizer use efficiency and quality of winter potato in Guangdong Province were studied.【Result】There
was no significant difference between the quality of potato tubers treated with organic fertilizer and chemical fertilizer. Among
the three organic fertilizer treatments, the commercial organic fertilizer 2 had higher total yield, marketable tuber yield and
total value than those of the other two commercial organic fertilizer treatments while the cost was lower than that of the other
two. The apparent fertilizer use efficiency of commercial organic fertilizer 2 was 10.17%, which was 1.96% and 3.52% higher
than that of commercial organic fertilizer 1 and commercial organic fertilizer 3, respectively. The organic manure equivalenceof commercial organic fertilizer 2 treatment was 66.02%. Overall, commercial organic fertilizer 2 was a better choice with a good
price in the process of replacing chemical fertilizer with organic fertilizer in winter potato. 【Conclusion】The organic fertilizer
could partly replace chemical fertilizer in winter potato cultivation, and achieve reduction of fertilizer application. |
