摘要
[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.[Result] The materials 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.The materials are more suitable for plant growth than chemical fertilizers,applying of which helps plants obtain better adversity resistance.[Conclusion] The ecological remediation materials for soil moisture can reduce the application of chemical fertilizers effectively and improve the production and quality of crops remarkably.
[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,并在9个省区26个物种48个品种的退化耕地、板结地、盐碱地和实验室内进行应用试验研究。[结果]该土墒生态修复材料及配套技术,从配方、工艺制造、应用均生态环保,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;该材料比化肥更适于植物生长,且施用该材料可使植物获得较好的抗逆性。[结论]该土墒生态修复材料可有效降低化肥施用量,显著提高产量和作物品质。
