Abstract To give full play to the production potential of Xiangyan 7 and to optimize the supporting planting technology， the effects of 9 different field structures on the yield and quality of Xiangyan 7 were studied by split plot design.The research results showed that the two field structures were 21 leaves left after topping and 4 leaves removed at the bottom， and 22 leaves left after topping and 5 leaves removed at the bottom.These two field structures were most favorable for Xiangyan 7 to obtain higher yield and better quality of tobacco leaves.
