干旱地区不同有机物料还田研究进展

Research Progress on Different Organic Materials Returning to Field in Arid Areas

有机物料还田是农林废弃物料综合利用的重要方式。在土壤中施加不同有机物料可以有效改善土壤结构,增加土壤水分和养分含量,提高土壤微生物数量和酶活性,是干旱地区节水保肥、实现作物增产的有效措施。对干旱区不同有机物料的还田现状、还田方式、有机物料还田对土壤物理特性、土壤养分含量、土壤微生物性状、作物生长的影响等方面的研究进行了综述,特别是对秸秆还田方面的研究做了全面总结。并在此基础上,提出有机物料还田存在的问题和建议,为有机物料还田在干旱地区的应用和推广提供理论参考。

Organic materials returning to the field is an important way to comprehensively utilize agricultural and forestry waste materials.Applying different organic materials to the soil can effectively improve the soil structure,increase soil moisture and nutrient content,and increase soil microbial population and enzyme activity.It is an effective measure to save water and fertilizer,and increase crop yield in arid areas.In this paper,researches on the present situation of returning,the patterns of returning,and the effects of different organic materials returning on soil physical properties,soil nutrient content,soil microbial traits and crop growth were systematically reviewed,especially on the research of straw returning.Based on this,the problems and suggestions for the returning of organic materials were proposed,which provided a theoretical reference for the application and promotion of organic materials returning in arid areas.
