摘要
为研究生物覆盖治理对坡地果园水土流失的影响,在坡地芒果园边坡种植生物栅篱、在梯面种植绿肥和覆盖秸杆,试验结果表明:生物覆盖综合治理区与对照区相比,平均减少水流失389.85m3/hm2,减少63.72%;土壤侵蚀量年平均减少4.66t/hm2,减少83.65%,土壤含水量平均提高4个百分点,且耕层土壤水分波动较小。
In order to study the effect of biological coverage on controlling soil and water erosion in slope orchard land, biological-fence were planted in slope land of mango, and green manure was planted and crop straw was covered in terrace. The results indicated that, as compared with the contrast orchard land, the average amount of loss reduction was 389,85 m^3/hm^2 and 63.72%, the average amount of soil erosion reduction was 4.66 t/hm^2 and 83.65%, and soil moisture increased 4 % and topsoil moisture had no obvious fluctuation.
