摘　　要：秸秆还田是培肥土壤和解决田间燃烧所产生的环境问题的重要方式,本文系统介绍了国内外秸秆还田的方式、时机、还田量、腐解特征和碳氮比的影响,阐述了秸秆还田及其技术对土壤物理性质、土壤养分、土壤微生物及作物生育和产量等方面的效应,着重概述了盐碱土秸秆还田研究的相关进展,并对今后研究方向进行了展望。文章提出在松嫩平原现有的土壤、气候条件下,秸秆还田需要配套合理的改良技术,与其他物理、化学、生物措施相结合,因地制宜,才能取得较好的效果。Straw returning is an important way for fertilizing soil and solving the environmental problems produced by combustion straw in field. Research situation on way, time, amount, decomposition characteristics, carbon and nitrogen ratio of straw returning were introduced in this paper. Effect of straw returning on soil physical properties, soil nutrient, soil microbial, crop growth and yield were summarized. This paper emphasized research progress of straw returning on saline soils. The future research prospects of straw returning technology were advanced. This paper presents, under the existing soil and climate conditions in Songnen Plain, Straw returning need to form a complete set of reasonable improvement technology, combined with other physical, chemical and biological measures. By adjusting measures to local conditions, better effect can be achieved.
