有机肥对我国盐碱地土壤改良及作物生长的影响

Effects of Organic Fertilizer on Soil Improvement and Crop Growth in Saline-alkaline Soil in China

  • 摘要: 盐碱地是我国重要的后备耕地战略资源,盐碱地的绿色改良与合理有效利用对于保障我国粮食安全具有重要意义。近年来,有机肥在农业生产中的应用越来越广泛,有机肥改良盐碱地的研究也备受关注。然而有机肥对盐碱地的改良效果受盐碱类型、原料种类、施用方式(单施、配施)、施用量、作物种类及施用年限等因素的影响,不同研究成果具有差异且缺乏系统总结,限制了有机肥在盐碱地中的发展与应用。综述了有机肥对我国盐碱地土壤理化性质、土壤微生物、作物产量及品质等方面影响的研究成果,从环境友好角度分析有机肥改良盐碱地的效果及存在问题,并结合我国国情提出有机肥在盐碱地中进一步研究的方向,以期为我国盐碱地绿色生态治理提供参考。

     

    Abstract: Saline-alkali land is an important reserve arable land strategic resource.Green improvement and rational and effective utilization of saline-alkali land are of great significance to guarantee our food security.In recent years, application of organic fertilizer in agricultural production is more and more extensive.However, improvement effect of organic fertilizer on saline-alkali soil is affected by types of salt and alkali, types of raw materials, application method(single application, combined application), amount of application, types of crops and application years.Conclusions of different studies are different and lack of systematic summary, which limits development and application of organic fertilizer in saline-alkali land.Effects of organic fertilizers on soil physical and chemical properties, soil microorganisms, crop yield and quality in saline-alkali soil were reviewed.Effects and existing problems of organic fertilizer improvement in saline-alkali land were analyzed from perspective of environmental friendliness, and further research direction of organic fertilizer in saline-alkali land was put forward according to our national conditions in order to provide reference for our national green ecological management of saline-alkali land.
