项目5大功率拖拉机配套农田作业装备研制主要研究内容针对我国北方旱作地区,重点研究为220.6~331 kW(300~450hp)段拖拉机配套的高速宽幅联合整地机械和高速宽幅气力输送式播种施肥联合作业机械。针对我国南方稻麦轮作区,重点研究秸杆还田深旋耕施肥播种复式作业机械。课题研究目标针对规模化农业生产对大型多功能联合耕种机械的需求,重点突破高速作业状态下宽幅机具液压折叠、种肥集中气力输送、精
Item 5 Research and development of high-power tractor supporting farmland equipment Main research contents Focus on the northern part of China’s dry farming areas, focusing on 220.6 ~ 331 kW (300 ~ 450hp) section tractor supporting high-speed wide joint preparation machinery and high-speed wide-format pneumatic conveying sowing Fertilizer joint operation machinery. According to the rice-wheat rotation area in southern China, we will focus on returning straw to deep-plowing, fertilizing and sowing double-cropped working machinery. Research objectives of the project for large-scale agricultural production of large-scale multi-functional cultivation of machinery needs, focusing on breaking the high-speed operating conditions under a wide range of hydraulic folding machine, concentrated fertilizer and concentrated pneumatic conveying, fine
