摘要
比较了炼山全垦、全垦和直接挖穴造林等 3种造林方式对红壤养分状况和土壤流失量变化的影响 .结果表明 ,炼山和全垦造林将明显增强土壤和养分的流失 ,导致土壤有机质、氮、磷。
Based on the measured data of soil nutrients and soil erosion, three afforestation methods, including controlled burning, full cultivation and bunch plantation, were compared .The results showed that both controlled burning and full cultivation enhanced erosion of soil and nutrients , caused decrease of organic matter, nitrogen , phosphate and potassium and led to degradation of soil fertility quality.
