秸秆还田的应用及其对环境的影响研究

Application of straw returning and its impact on the environment

随着粮食生产技术的发展和农村生活水平的提高,秸秆的生产和利用发生了巨大变化。我国秸秆年产量超过9亿t,大量秸秆在未经利用的情况下被随意丢弃或焚烧,使环境遭到严重污染。秸秆还田作为秸秆资源化利用的一种有效途径,在国内外逐渐得到重视和应用。介绍秸秆还田的应用方式和方法,探讨秸秆还田对环境产生的影响,以期为秸秆还田技术的推广和发展提供参考。

With the development of grain production technologies and improvement of rural living standard,the production and utilization of straw have significantly been changed.More than 900 million tons of straw are produced per year in China,and a large amount of them are randomly discarded or incinerated without utilization,causing serious environmental pollution.As an effective approach for the resourceful utilization of straw,straw returning has been gradually stressed and applied both in China and abroad.This paper introduced the modes and methods of straw returning and discussed its impact on the environment,providing a reference for the extension and development of the straw returning technique.
