【摘要】 针对我国北方干旱和半干旱地区因春旱引起的播种难出苗以及因土壤缺墒造成的诸多耕作问题,讨论了机械化保护性耕作技术和行走式节水补灌两项抗旱耕作适用技术的内容、特点及其发展历程;并对两项技术的共同性和互补性进行了分析;建议在研究、开发、试验、示范、推广和运用中集成配套,对两项抗旱耕作技术现有适用机械的主要结合点(免耕施肥坐水播种联合作业机)做进一步的研究,提高其通用性与精准性,以彰显免耕施肥坐水播种联合作业工艺的优势,达到干旱地区抗旱节水与增产节支的目的。更多还原

【Abstract】 For the farming problems that were caused by being lack of soil moisture in North of China where is farm belt depending on rain or severity aridity area.on the base of discussing the content,characteristic and their developing course of mechanization conservation tillage technology and walking water-saving and irrigation-supplementing machines and analyzing the intercommunity and complementariness of the two technologies.Suggest that can realize their integration and matching in the course of research,exploitation,test,demonstration,generalizability and application,especially,main combine point which is fit for machine in existence of two drought resistance farming technologies need to be researched to improve their universalizable performance and precision.Intend to achieve the aim of drought resistance,water saving,increase production and cost saving.更多还原
