Abstract:
Taking the rhizosphere soil of 5-year-old blueberry plants growing well and growing weakly were used as research object，the soil bulk density and total porosity of soil were determined by cutting ring joint method；the soil structure was analyzed through the dry sieving method and wet sieving method.The results showed that there was a positive correlation between blueberries growth and soil total porosity，and a negative correlation between blueberries growth and the soil bulk density.The proportion of aggregates more than 0.25 mm of soil from blueberry plants with good growth was more than that of growing weakly.The structure retention rate was also significantly greater than weak blueberry rhizosphere.There were significant and extremely significant differences between rhizosphere soil of blueberry plants growing well and growing weakly in soil bulk density，total porosity and soil structure.
