中文摘要根据干热河谷区生态环境脆弱.土壤贫瘠,有机质含量低的现状,研究本区种植豆科豆科牧草和灌木部分生态与改良的土壤效应.结果表明:(1)小气候得到改善,豆科牧草和灌木种植样地表及土壤湿度大于未种植地,温度低于未种植地.(2)随着豆科牧草和灌木种植年限增加,土壤肥力得到提高,土壤中全氮、速效钾及pH值含量逐年增加.土壤物理性质得到改善,土壤容重比未种植地低,孔隙度及田间持水量比未种植地高,持水能力增强.
英文摘要Based on the soil environment character and the lower soil organic carbon content, the effect of Legume grazing and shrub on ecological restoration and soil amelioration is studied in Yuanmou arid-hot valleys. The results showed that: (1) After planting, the microclimate was improved, for example the humidity of the earth’s surface and the restoration plot’s soil of grazing and shrub was higher than that of bare land, but the temperature of them was smaller than that of bare land. (2) With the increasing years of planting, the fertility of the soil was enhanced, such as the content of the soil organic carbon, total N, available potassium and soil Ph, and the physical properties were also ameliorated, for example the soil bulk density (SBD) of the restoration plot of the grazing and shrub was lower than that of bare land, but the porosity and field water holding capacity were higher than that of bare land, the field water holding capability were increased.
