施肥对婆婆纳、离子芥、小花糖芥3种麦田杂草根际pH的影响

pH of rhizospheric soil with Veronica agrestis,Chorispora tenella,and Erysimum cheiranthoides in winter wheat field under different fertilization treatments

  • 摘要: 根际是受根系影响而在物理、化学和生物学性质等方面均不同于土体的极小部分土壤区域.研究表明:植物生长过程中,由于根系的代谢作用而向根外排泄H 或HCO3-,使根际土壤pH发生较大变化.而根际土壤的pH直接影响到土壤养分的活性和生物有效性.故不同植物根际土壤的pH状况可反映出它们对土壤氮、磷、钾养分吸收利用能力的相对大小.
