摘　　要：根据沿海盐碱地饲草―短季棉连作种植模式的特点,设计一款新型的基于北斗导航的棉花智能播种机。该机具可一次完成北斗导航无人驾驶、播种带清整、种下分层施肥、种肥隔离、智能精量播种、种肥隔离、覆土镇压、地表塑形等工序。利用该机具进行田间试验,结果表明:作业后的衔接行准确,播行端直,提高了衔接行的精准度和播行的直线度,播深平均为2.8 cm;播深合格率为92.5%;衔接行间距精度为1.2 cm;播种行直线度为0.8 cm,土地利用率提高5%。为后续田间标准化作业奠定基础,实现播种施肥精准控制,节种节肥。According to the characteristics of forage short season cotton continuous cropping mode in coastal saline alkali land,a new intelligent cotton planter based on Beidou navigation was designed.and the seed is made,and the layering is fertilized.The machine can complete the unmanned Beidou navigation,sowing belt cleaning,layered fertilization under seed,seed and fertilizer isolation,intelligent precision sowing,seed and fertilizer isolation,soil covering and pressing,surface shaping and other processes at one time.Field experiments are carried out with the machine.The results show that the accuracy of the link line and the straight end of the broadcast line are accurate,which improves the accuracy of the link line and the straightness of the broadcast line,and the average depth of the broadcast is 2.8 cm;The qualified rate of sowing depth was 92.5%;The accuracy of connecting line spacing is 1.2 cm;The straightness of sowing line was 0.8 cm,and the land use efficiency was increased by 5%.It lays the foundation for the follow-up standardized operation in the field,realizes the accurate control of sowing and fertilization,and saves seed and fertilizer.
