辽西地区紫穗槐对土壤化学性质改良效果研究

Effects of Amorpha fruticosa on Soil Chemical Properties in Western Liaoning Province

以室外取样和室内试验分析相结合的方法,对不同立地条件下紫穗槐改良土壤效果进行研究。结果表明,研究地区紫穗槐在不同立地条件下生长发育状况和改良土壤效果有较大差异,紫穗槐通过根系的生长活动和作用,增加了N、P、K含量,改良了酸性土壤,从而更适合植物的生长。

Adopting combination of outdoor sampling and indoor real test analysis,soil-improvement effect by Amorpha fruticosal under different site conditions was studied. Result shows that growth status soil-improve-ment effect of Amorpha fruticosal in the research area under different site conditions are different, through the growth of root system activity and function, the soil moisture content increased, N, P, K content Amorpha frutico-sal were increased and were acid soil improved, which is more suitable for plant growth and activities.
