Abstract: The transplanting machine of bowl young seedling made of plant was manufactured according cultivated technical demands. The research was focused on six rows rice seedling transplanting machine which was homemade in Yanji, and the bench tests and simulation tests for assembled whole machine of vertical feed mechanism, horizontal feeding mechanism, setting for supporting and cutting and orientation of the separtated seeding, and disposal of ort after planting were done to the machine. The tests were done for many years and the results showed that the research reached demands for planting, and the rate of injured seedlings was 1.8%, the downfallen rate was 3.2%, the misplanting rate was 2.0% and the passing rate of uniformity was 94.6%. The technical parameters are provided to refit other kinds of rice seedling transplanting machines.
