南方红黄壤区经济植物篱配合平衡施肥的水土保持效应研究
- Title:
- Effect of Soil and Water Conservation with Balance Fertilization Combined with Economic Plant Hedge in Southern Red-yellow Soil Area
- 分类号:
- S157
- 摘要:
- 研究结果表明,水土流失不仅跟降雨量有关,还跟覆盖度有关,采用经济植物篱配合平衡施肥,可明显防治坡地的水土流失,与传统的农民习惯种植方式相比,可减少土壤流失88.58%～89.25%,减少径流量1.8%～8.20%.增加玉米产量52.03%(经济植物篱黄花菜+平衡施肥),增加农民收入263.28%～265.7%.经济植物篱配合平衡施肥对坡耕地的可持续利用起到了极大的作用.
- Abstract:
- The research result shows:soil and water loss has not only related with precipitation,but also the coverage.Using economic plant hedge combined with balanced fertilization can obviously reduce soil and water loss on sloping field,compared with traditional cultivating way,it can reduce soil loss about 88.58%～89.25% and runoff 41.48%～48.20%.Meanwhile,it can raise maize yield by 52.03%(economic plants hedge daylily+balanced fertilization),increase the peasants’ income by 263.28～265.74%.This method plays an important role in using slope field continuously.
