    红壤缓坡花生地不同水土保持措施效果分析

    Benefit analysis of different soil and water conservation measures at sloping Arachis hypogaea land with red soil

    • 摘要: 采用径流小区试验,以花生常规种植为对照,研究红壤荒坡花生地花生+草篱、花生+覆盖+草篱、花生+覆盖3种种植措施的水土保持效果。试验从4月份花生种植后开始测定,8月底花生收获结束。结果表明:1)3种种值措施地表径流量均随日降雨量的增大而增大;2)3种种植措施地表径流量、土壤侵蚀量均与对照差异显著(P<0.01)。表明,花生+覆盖+草篱是红壤缓坡花生地有效的水土保持措施。

       

      Abstract: Taking conventional cultivation of Arachis hypogaea as control, effects of different soil and water conservation measures were analyzed at sloping Arachis hypogaea land with red soil by using runoff plot experiment. The measures are Arachis hypogaea+ grass hedge, Arachis hypogaea + cover + grass hedge, and Arachis hypogaea+ cover. This experiment began in April after determination of Arachis hypogaea planting, and ended in August after Arachis hypogaea harvest. Results showed that: 1) The surface runoff of three kinds of measures increased with the increase of daily rainfall; 2) the surface runoff and soil erosion of three kinds of measures differed significantly with control (P<0.01). That Arachis hypogaea + cover + grass hedge should be the effective Arachis hypogaea soil and water conservation measure at sloping Arachis hypogaesa with red soil.
