| 摘 要： | 为解决豫西南丘陵坡地的水土流失问题,开展了种植龙须草、紫穗槐与次生植被的对比试验。结果表明,人工种植龙须草、紫穗槐改善了土壤的物理性状效果显著(p<0.05),使土壤容重分别降低了9.15%和10.56%,土壤总孔隙度分别增加了10.56%和12.28%;土壤非毛管孔隙度分别增加了38.64%和42.93%;土壤毛管孔隙度分别增加了4.78%和5.98%。种植龙须草、紫穗槐土壤蓄水保水能力提高显著(p<0.05),其中土壤毛管最大持水量分别增加了15.35%和18.49%,土壤饱和含水量分别增加了18.14%和19.57%,土壤饱和贮水量分别增加了4.10%和4.42%。人工种植龙须草、紫穗槐土壤的渗透率提高显著(p<0.05),其分别是次生植被的2.09倍和2.17倍。茎叶吸水率:龙须草>紫穗槐>次生植被。试验还表明,种植龙须草和紫穗槐3a后,地面径流深、土壤侵蚀量和土壤养分流失量低于次生植被。 |

| Abstract: | In order to control soil erosion on hilly upland in Southwest He′nan Province,comparative experiments were conducted among Eulaliopsis binata,Amorpha fruticosa and secondary vegetation.Results showed that Eulaliopsis binata and Amorpha fruticosa could significantly improve soil physical properties(p<0.05): soil bulk density was lowered to 9.15% and 10.56%;total porosity was raised to 10.56% and 12.28%;non-capillary porosity was increased to 38.64% and 42.93%;and capillary porosity was increased to 4.78% and 5.98%,respectively.Planting Eulaliopsis binata and Amorpha fruticosa could remarkably improve soil water storage and conservation capacity(p<0.05): moisture capacity was raised to 15.38% and 19.57%;soil maximum capillary moisture capacity,18.14% and 19.57%;and saturated soil water content,4.10% and 4.42%,respectively.Soil permeability was apparently improved(p<0.05): compared with secondary vegetation,artificially planted Eulaliopsis binata and Amorpha fruticosa could raise soil permeability by 2.09 and 2.17 times respectively.The water absorption rates of stem and leave were: Eulaliopsis binata>Amorpha fruticosa>secondary vegetation.In addition,results showed that the depth of surface runoff,the amount of soil erosion and the amount of soil nutrient loss in the areas with three years′ Eulaliopsis binata and Amorpha fruticosa planting were lower compared with those with secondary vegetation only. |
| Keywords: | Eulaliopsis binata Amorpha fruticosa soil and water conservation artificial planting hilly upland |
