万能通用精准播种机的研究与试验

通过对排种机理的研究，阐述了播种机两大系列产品的通用化问题。通过对锥盘式小麦精准播种机的研究、应用及改进，解决了以锥盘式精准排种器为基础、以“一组三行”播种单体为基型的播种机通用化问题。

Experimental Study on a General Precision Planter

There have been being the two different types of planters, that is, drill and hill drop drill and both of them are general service within the extent of certain conditions. However, they haven't been being beyond the scope of their traditional styles of planting. In this work, a wheat precision planter with the conical plate type metering device which have been with three planting rows was developed, which was a successful approach to solve the spacing contradiction of wide and narrow rows and the dimensional contradiction of large, middle and small seeds between drilling and precision drilling. The new developed planter realized an economic and efficient process of planting.
