【摘要】 [目的]对退化土地生态修复材料及技术进行研究。[方法]针对中国土地出现的土墒地力条件退化的具体原因,研究以环境友好的层状硅酸盐为基料、秸秆还田为手段的土墒生态修复材料及配套技术,并对9个省区26个物种48个品种的退化耕地、板结地、盐碱地进行应用试验研究。[结果]该土墒生态修复材料及配套技术环境友好,从配方、工艺制造、应用配套技术均生态环保,没有任何对造成土地二次污染的隐患;该材料及配套技术以修复土地土墒条件(水、肥、期、热、生)的良性平衡,建立稳定的循环圈核心,实现粮食增产。[结论]该土墒生态修复材料及配套技术原材料分布广泛、价格低廉,其中部分原材料是现在还在造成环境污染的材料,该材料及配套技术的实施,是一个环保建设项目。更多还原

【Abstract】 [Objective] The paper aimed at researching on the ecological remediation materials and related technologies in degraded land.[Method] Pointing at the specific reasons for degradation of soil moisture and fertility conditions,the ecological remediation materials and related technologies for soil moisture had been studied using layered silicates as substrate materials and using straw turnover as the method.The application research had been carried out in degraded cultivated land,compacted land,saline-alkali soil and laboratory of nine provinces and regions on 26 species and 48 varieties.[Results] The material and related technologies are environment-friendly in formula,processing,application with no hidden trouble as secondary pollution,which can be used for the restoration of positive balance of soil moisture conditions(water,fertilizer,gas,and heat),establishment of the core of a stable circle and improving food production steadily.[Conclusion] The raw materials of the ecological remediation materials related technologies for soil moisture are widely distributed and low in price,some of which are still causing pollution at present.The application of this materials and related technologies is a construction project of environmental protection.更多还原
