Abstract: Domestic deep pine plowshare was designed and produced.Under the same test conditions，comparative test about wear resistance and working quality between domestic deep pine plowshare and imported deep pine plowshare was carried out.Results showed that there was little difference between two kinds of plowshare.But mean square deviation of domestic plowshare was larger.It showed that domestic share production technology was not stable and wave of wear resistance was larger.In terms of quality of work，domestic deep pine plowshare and imported deep pine plowshare were at same level.Job performance of domestic deep pine plowshare was stable and it met requirements of relevant standards.
