0引言冬小麦精密播种高产栽培技术是一套高产、稳产、优质、低耗、经济效益高和生态效益好的栽培技术体系,为实现和推广这项农艺技术,必须有与之配套的高性能小麦精密播种机。目前,生产中推广的小麦精密播种机均采用机械式排种器,种子在田间粒距分布仍属稀条播,播种量远远超过精播的播种量,现在生产上迫切需要能够实现播量在25~45 kg/hm~2、播种均匀一致的小麦单粒精密播种机。奥地利Wintersteiger公司生
0 Introduction Winter wheat precision sowing high-yielding cultivation techniques is a set of high-yield, stable yield, high quality, low consumption, high economic efficiency and good eco-efficiency cultivation technology system, in order to achieve and promote this agronomic technology, there must be associated with high-performance wheat Precision planter. At present, the precision wheat planter popularized in production adopts the mechanical seed metering device. The seed grain distribution in the field is still thinly sowed, the sowing amount far exceeds the sowing amount of the sowing seed, and the urgent need in the production now can realize the sowing rate 25 ~ 45 kg / hm ~ 2, sowing uniform wheat precision grain planter.
