- 摘要:
- 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>0.25 mm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。
- 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.
