摘要： 为探究轮作与减量施肥对轮作系统作物产量及土壤养分影响，优化金花菜（Medicago polymorpha）-水稻 （Oryza sativa）轮作体系下施肥量，本研究采用双因素完全随机试验设计，设置“水稻连作（高肥）”“金花菜（不施肥）+水稻（中肥）”“金花菜（施肥）+水稻（中肥）”“金花菜（不施肥）+水稻（低肥）”和“金花菜（施肥）+水稻（低肥）”5种处理。结果表明减量施肥处理轮作系统产量及土壤养分差异较大，金花菜（施肥）+水稻（低肥）处理水稻产量较同年其他处理最高，有机质较其他处理整体显著增加14.81%～38.13%，土壤pH较其他处理降低2.34%～5.03%，土壤氮素含量较其他处理也显著增加0.80%～35.66%（P<0.05）。因此，轮作减量施肥可有效提高轮作系统产量与土壤养分。

Abstract: To explore the effects of crop rotation combined with reduced fertilization on crop yield and soil nutrients in the rotation system, and to optimize fertilizer application in rotation system of burclover (Medicago polymorpha) -rice (Oryza sativa), this study adopted the double-factor completely randomized design, and set up five treatments, including "continuous cropping rice (high fertilizer)" "burclover (no fertilizer) + rice (middle fertilizer)" "burclover (fertilizer) + rice (middle fertilizer)" "burclover (no fertilizer) + rice (low fertilizer)", and "burclover (fertilizer) + rice (low fertilizer)". The results showed that there were significant differences in yield and soil nutrients with the reduced fertilizer in rotation system. The highest rice yield in the treatment of "burclover (fertilizer) + rice (low fertilizer)" was higher than the other treatments in the same year, with organic matter significantly increased by 14.81%~38.13%, soil pH reduced by 2.34%~5.03%, and soil nitrogen content significantly increased by 0.80%~35.66% (P<0.05). Thus, reducing fertilizer application in crop rotation can effectively improve yield and soil nutrients in crop rotation systems.
