Abstract: The soil enzyme activities were investigated in orchard of the Ziziphus jujuba in Huanghekou Town of Kenli,Dongying,Shandong Province.The results indicated that the soil enzyme activity decreased with the soil layer deepening.Urease had remarkable positive correlation with peroidase and catalase,its correlation coefficients was 0.996 and 0.943 respectively;Urease had little correlations with polyphenal oxidase and correlation coefficient was 0.337;Catalase had remarkable positive correlation with polyphenal oxidase and correlation coefficient was 0.911;Polyphenal oxidase had little correlations with other three enzymes.Soil enzymes had remarkable correlations with soil nutrients,pH and soil microorganism.Among them,urease had remarkable correlation with soil nutrients,pH,azotobacteria,fungi,bacteria,and correlation coefficient was above 0.444;Polyphenal oxidase had little correlations with soil nutrients and microorganism;peroidase and catalase had remarkable correlation with soil nutrients,pH,fungi and cellulolytic bacteria.The correlation coefficient was above 0.451.

Key words: jujube orchard, soil enzyme, soil nutrient, soil microbe, saline land
