摘要
土壤有机质对土壤的物理、化学和生物性质都有着积极影响,它也是土壤肥力的主要标志,秸秆还田是恢复和保持土壤有机质含量的基本途径。阐述了我国稻麦秸秆还田技术的发展和研究现状,并按照秸秆还田的深度进行了详细的归纳和分析,从中梳理出秸秆还田作业机的发展历程和方向,并对今后秸秆还田技术的研究提出了意见和建议。
Soil organic matter has positive impacts on its physical,chemical and biological properties,and the level of its content is a main symbol of soil fertility. Straw returning to field is the most basic way to restore and maintain the content. Current status of development and research of straw returning technology were described. Induction and analysis in detail were made in accordance with the straw depth,from which development process and direction of straw returning machine were teased out.Some opinions and suggestions for the future research of straw returning technology were put forward.
