摘　　要：在3年肥力定位试验地上进行不同土壤肥力对芝麻生长发育及产量和效益的影响研究。结果表明,芝麻株高、叶面积、叶片数、干物质质量均随土壤肥力的提高而增加,处理间差异均达极显著水平。土壤肥力越高芝麻籽粒产量和效益越高。处理1-4产量分别比处理5减产48.86%、55.52%、42.88%和28.18%,经济效益分别比处理5降低了49.87%、50.48%、36.40%、20.04%。在土壤基础地力较低的条件下,作物产量在本地同土壤类型居中高水平,为作物减量施肥、节资增效提供依据。The effects of different soil fertility on growth and development, yield and benefit of sesame are studied. The results show that, the plant height, leaf area, leaf number and dry matter accumulation of sesame increase with increase of soil fertility, the difference of treatments has reach extremely significant level. The yield and benefit of sesame increase with increase of soil fertility. Compared with treatment 5, the yield of treatment 1-4 is respectively reduced by 48.86%, 55.52%, 42.88%, 28.18%, the economic benefit is reduced 49.87%, 50.48%, 36.40%, 20.04%. Under the condition of low soil foundation soil fertility, the yield of crop is better level than same soil types, provide the basis for reducing crop fertilization section and increasing efficiency.
