| 摘 要： | 测定了在不同溶液酸度、不同离子强度和Ca~(2+)/Al~(3+)比下,铝对马尾松幼苗生长状况的影响。结果表明,溶液酸度增加,离子强度减小时,铝的毒害作用增大。钙对铝毒有明显缓解作用,当Ca~(2+)/Al~(3+)增大时,铝的毒性减小,但其缓解作用与铝浓度有关,当铝浓度增加,钙的缓解能力下降。

| Abstract: | The effects of aluminum on masson pine at different ionic strengths ,pH values and Ca2+/Al3+ ratios were evaluated. The results indicated that the aluminum toxicity was increased with the decrease of pH value or ionic strength and could be alleviated by Ca. The influence of Ca on the Al toxicity was weakened at high Al concentration. |

| Keywords: | Ca2+/Al3+ masson pine ionic strength pH |
