摘要
作物秸秆还田是有效利用秸秆资源的重要途径。作物秸秆还田对土壤结构和养分状况、温室气体排放和作物产量等会产生明显影响。为了充分利用作物秸秆资源,并探讨其还田效用,综述了作物秸秆还田相关技术、秸秆还田对稻田土壤性状、水稻产量和米质以及温室气体排放的影响,并从秸秆还田轻简栽培技术、不同稻作方式下秸秆还田的环境效应及不同作物类型秸秆还田效应等方面提出了未来深入开展秸秆还田研究的建议,以期为合理利用作物秸秆、提高水稻产量和改善稻米品质以及保护环境提供理论依据。
Straw returning is an important way for effectively using the straw resources. Straw returning has great effects on soil structure and nutrient situation, greenhouse gas emission and crop yield. In order to make full use of straw resources, and discusses the straw utility, this paper summarizes the returning techniques, and the effects of straw returning on soil characteristics, rice yield, grain quality and greenhouse gas emission. The paper also gives advice on the future research on extensive straw returning in terms of simplified cultivation with straw returning, the environmental effect of straw returning under different rice cultivation models and the effect of different crops straw returning, hoping to provide a theoretical basis for rational utilization of crop straws, imorovintt the yield and aualitv of rice and protecting the environment
