以5年生长势强和弱的蓝莓植株根际土壤为研究对象,采用环刀联合法、干筛法、湿筛法,研究了蓝莓植株根际土壤容重、土壤总孔隙度和土壤结构对蓝莓植株长势的影响。结果表明:蓝莓长势与土壤总孔隙度呈正相关,而与土壤容重呈负相关;长势强的蓝莓根际土壤>0.25mm团粒所占比重大于长势弱的蓝莓根际土壤,结构保持率也明显大于长势弱的蓝莓根际土壤;长势强与长势弱蓝莓根际土壤容重、总孔隙度、土壤结构分析各指标在0.05和0.01水平存在显著和极显著差异。
Taking 5 years growing strong and weak blueberry plant rhizosphere soil as the research object, we studied the effect of blueberry plant rhizosphere soil bulk density, total soil porosity and soil structure on the blueberry plant The impact of growth. The results showed that the growth of blueberry was positively correlated with the total porosity of the soil and negatively correlated with the bulk density of the soil. The proportion of> 0.25mm aggregates of the growing blueberry rhizosphere soil was larger than that of the weaker blueberry rhizosphere soil, and the structure retention rate was also significantly greater Growing weak and weak blueberry rhizosphere soil; weak and growing weak rhizosphere soil bulk density, total porosity, soil structure analysis of each index at 0.05 and 0.01 levels there is a significant and very significant difference.
