摘要
针对我国近年来大功率拖拉机的广泛应用,急需配套大型耕作机具的市场需求,在吸收国外最新耕作技术和配套机具的基础上,结合我国的农业耕作技术要求,研究设计了新型复式少耕整地机械,一次作业就可完成有利于农作物生长的3层土壤耕层结构。大面积生产试验表明,该机具有显著的经济效益、社会效益和生态效益,对于发展效益型农业和可持续农业具有重要意义。
The project studies aim the extensive application of high - power tractors In China in recent years, urgent need for supporting large - scale farming equipment market needs, on the basis of the absorption of foreign technology and supporting the latest farming equipment, combined with the technical requirements of china＇s agricultural practices, study and design new multiple - small - tillage equipment tha achieve three - tier structure of soil tha Is conducive to the growth of crops one - stop o Large - scale production test showed that the aircraft has significant economic, social and ecological benefits, promote the use of this equipment have significance to development of efficiency and continuance agriculture.
