Sustainable development agriculture and organic cultivation get more and more attention. The effects of different mechanical planting methods on the yield, quality and aroma of the conventional fragrant rice variety 19 Xiang under the organic cultivation conditions were studied. In this experiment, four treatments were set up, namely mechanical transplanting with dry transplanter （DD）, mechanical transplanting with water transplanter （DW）, mechanical dry direct seeding （D）, conventional water transplanting method as the control （CK）. The results showed that, there was no significant difference in effective panicle number, grains per panicle, seed-setting rate, 1000-grain weight and yield between DD treatment and CK, while the yield under D treatment decreased significantly. Compared with CK, DD, DW and D treatments significantly inhibited the expression of BADH2,a key inhibit gene of rice aroma synthesis, thereby enhancing rice aroma, with the highest content of aroma substance （2-acetyl-1-pyrroline） under DD treatment. In conclusion, the mechanical transplanting with dry transplanter is suitable as a mechanical planting method under organic cultivation conditions.
