Medium-small no-till wheat planter hasn’t already satisfy power need with the development of high-power tractor in the Mongolia and Sinkiang large farms, which restricted the application of conservation tillage. Therefore, it is necessary to study the large no-till planter matching with high-power tractor. Adopted the controlled flume dense dentiform seed meter to perform precision metering, the 2BMG-24 no-till wheat planter was designed. Furthermore, the wavy disc coulters were used to cut stubble for sowing, and the double disc coulters were used to open furrow for fertilizing. The results of field test showed that the eligibility ratio of seed depth, the variance coefficient of metering equality and the seed damaged rate were 91%, 28% and 0.1%, respectively. The operating performance of this machine was equal to that of the overseas machines. At the same time, the cost was much lower than them, reduced by 60%～70%. Its application can save 16 kg/hm2 fuels and increase 15%～20% incomes. Thus, the 2BMG-24 no-till wheat planter can meet with the need of large farms, which is an indispensable equipment for the development of the China conservation tillage.
