摘要
免耕技术是用联合作业免耕播种机在前茬地上一次完成切茬、开沟、喷药除草、施肥、播种、覆土等多道工序的播种技术。免耕技术能尽量减少土壤耕作次数,减少土壤压实程度,保护和改善土壤结构,从而提高播种质量。为此,通过对发展保护性耕作的背景和意义的分析,论述了目前我国免耕播种机发展的现状以及存在的问题,并探讨了我国免耕播种机的发展前景,指出了免耕播种机在我国具有广阔的发展空间。
No-tillage technology is a kind of seeding technique which means using no-tillage planter to complete multi-procedures including cutting stubble, ditching, drug spray, weeding, fertilizing, seeding, earthing, in first stubble field once. It can reduce cultivated frequency and soil compactedness, protect and improve soil structure, then improve seeding quality. Hence, through analyzing the background and significance of protective cultivation, this paper states present situation of no-tillage planter and its defects, and discusses its development prospects in China.
