机械化秸秆粉碎直接还田技术及其效益

Technology of Mechanical Crush-up of Stalks for Direct Returning to Farmland

从忻州地区多年来推广机械化秸秆粉碎还田的实际出发，从理论和实践的结合上，论述了发展机械化桔秆粉碎直接还田技术的必要性技术要求及综合效益。对其增产增收机理进行了科学的分析，并探讨了影响其技术效益的主要因素和解决的关键措施，得出结论：机械化秸秆粉碎直接还田技术是一项发展有机旱作农业，实现农业节本增效有效措施。

Starting from the actual conditions of mechanical crtish-up of stalks fordirect rettirning to farmland extended for many years,this paper deals with the basic re-quirements and comprehensive economic returns for developing mechanical crush-up ofstalks for direct returning to farmland both in theory and in practicea,analyses themechanism of vield increase and income increase,and discusses the major constraints af-fecting its technological benefits and the key measures to be taken. It comes to the con-clusion that technology of mechai1ical crush-up of stalks for direct returning to farmland is an effective measure to develop organic rainfed agrictilture and realize cost- saving andbenefit- increasing agriculture.
