| 摘 要： | 目的]探讨水土保持措施对低丘坡地红壤硒的保持效果。方法]通过野外观测采样和室内测定，分析了不同水保小区的土壤总硒水平，找出不同水保措施改良土壤硒保育效果的差异，同时找出土壤硒的最佳水土保持措施。结果]各种措施保育土壤硒效果顺序为：标准水平梯田＋梯壁百喜草＋前埂后沟〉标准水平梯田＋梯壁百喜草〉纵坡间种（套种黄豆和萝卜）〉柑橘净植〉横坡间种（套种黄豆和萝卜）〉标准水平梯田＋梯壁清耕〉百喜草带状覆盖（果树-草）〉百喜草全园覆盖（果树-草）〉百喜草全园覆盖〉全园裸露。结论]该研究可为南方山区果业开发中采取科学的水保措施、有效保护土壤硒提供可靠依据。

| Abstract: | Objective J The aim was to explore the red soll selenium conservation benefits of soil and water conservation in hills. Method ]The soil selenium content in different treatment plots were analyzed by field experimental observation and indoor analysis, the differences of selenium conservation effect of different treatment plots was obtained, as well as the optimum soil and water conservation measure. Result] The result in- dicated that the effects of different modified measures to soil selenium in Citrus reticulate Banco orchard was as follow ： standard horizontal terrace ＋ Paspalum natatum planting on terrace ＋ rand in the front and ditch in the back 〉 standard horizontal terrace ＋ Paspalum natatum planting on terrace 〉 inter planting on longitudinal slope 〉 citrus planting only 〉 inter planting on cross slop 〉 standard horizontal terrace clean tillage on terrace 〉 Paspalum natatums strapping cover（ citrus-Paspalum natatums） 〉 Paspalum natatum totally cover（citrus-Paspalum natatums） 〉 Paspal- um natatum totally cover（ only Paspalum natatums） 〉 totally clean tillage. Conclusion ] The study can provide reliable basis for scientifically carrying out the soil and water conservation measures to effective protect soil selenium during fruit industry in south hilly areas. |
