摘　　要：本文运用外业调查和内业分析的方法,研究了土壤的理化性质与柑桔产量的相互关系。分析结果表明:土壤三相、土层深度、土壤容重,土壤pH值以及土壤化学性质与产量关系显著。据此提出了改良柑桔低产园土壤的几条途径。The Gorrelationship between the physical and chemical properties of the soil and the yield of satsuma orange (Citrus reticulata) was studied through field investigations and office/lab work. The analysis indicated that the yield was markedly affected by soil phases, tie Solum depth, thebulk density of soil, the soil pH value and the chemical properties of the soil. Several approaches are proposed to improve the low yield status of the orange orchards in Shuangpai County of Hunan province.
