| 中文摘要 | 通过连续6年对粮经果复合垄作模式的研究结果表明:粮经果复合垄作模式使土壤含水量增加,具有显著的保水效益;粮经果复合垄作以聚土垄作与农林复合为基础,在减少用工投入的基础上增加系统产出、减少径流、控制土壤侵蚀与降低非点源污染方面起得非常重要的作用;粮经果复合垄作能有效改善坡耕地土壤结构,提高土壤养分的含量。垄作的物理阻挡作用对土壤径流的截持与减少泥沙的流失,有效的改善了土壤的养分含量。粮经果复合垄作模式比粮经果复合平作模式土壤孔度提高9.38%。粮经果复合垄作模式增加了<0.02 mm土壤颗粒含量。与纯粮顺坡平作相比,径流量、侵蚀量平均减幅分别为97.83%,47.49%。坡耕地粮经果复合垄作水保效益显著,经济效益高,广泛适于三峡库区坡耕地的利用模式。 |
| 英文摘要 | Study on affection compound farming of grain-case crop-trees of slope croplands to soil features in Three Gorges reservoir area,soil conservation measures including contour tillage of wide ridge and furrow covering and compound farming of grain-case crop-trees formed vertical agricultural structure of slope crop land.Results show that technique of compound farming of grain-case crop-trees play an important role in improves soil water and soil nutrient and soil instruct.Runoff detention by compound farming of grain-case crop-trees can effectively reduce soil nutrient loss and improve soil nutrient content.The results showed that this technique had good ecological and economic effects,could improve the soil fertility,increase the soil effective water content,protect the soil and promote the land productivity.The results showed that this mode could effectively reduce soil and water loss of purple soil slop.The decrease of soil erosion amount is more evident in comparison with tradition model-run off amount decreased by 97.83% and soil erosion amount decreased by 47.49%. |
