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。
The runoff plots were used to study the effects of soil and water conservation on the perennials in red soil peanut with three peanut planting measures: peanut + grass hedgerow, peanut + mulch + grass hedgerow and peanut + mulching. The test was started after the peanut plantation in April and the peanut harvest ended at the end of August. The results showed that: 1) The surface runoff of 3 kinds of measures increased with the increase of daily rainfall; 2) The surface runoff and soil erosion of 3 planting measures were significantly different from the control (P <0.01). It shows that peanut + grass cover + hedgerows is an effective soil and water conservation measure for gentle slope peanut.
