不同施肥处理对侵蚀性红壤酸性和交换性能的修复效应
Restoration effect of different fertilizations on the acidic and exchange property of eroded red soil
摘要
Abstract
In order to understand the remediation effect of different fertilization structure on eroded soil, a pot experiment was conducted to investigate the restoration effects of Chemical fertilizer (NPK), NPK + Organic fertilizer (NPKM), NPK.+ Soil conditioner R2 (NPKR2), No fertilization (CK) on the acidic and exchange properties of eroded red soil which developed from different parent materials. The results indicated that treatments of combined application of organic and inorganic fertilizers (NPKM) and combined application of inorganic fertilizer and soil conditioner 2 (NPK.R2) could increase pH and buffer capacity significantly while the single fertilizer treatment (NPK) had no obvious effect. Treatment NPKR2 could ameliorate and decrease the acidic property of soil. Treatment NPKM could only increase pH buffer capacity of the soil, but not increase soil pH significantly. Treatment NPKM could increase the content of the organic matter of the soil, but the content of organic matter was not positively related to the pH buffer capacity of the soil. Each treatment could decrease the activity of Al3+ in the soil. Treatment NPKR2 decreased Al3+ in granite red soil significantly while the other two treatments had no obvious effects. Soil CEC of each treatment had little change and ECEC of the soil under treatment NPKR2 was significantly greater than that under the other treatments. ECEC of plevthific horizon red soil and homogenous layer red soil treated bylhe fertilizer treatments was higher than that treated by the no fertilizer treatments, only treatment NPKR2 showed significant effect on granite red soil and plate shale red soil.关键词
