Abstract:Taking the purple sweetpotato variety Taizhong 11 as material,the rules and characteristics of stem and leaf growth,root tuber yield formation and dry matter accumulation were studied under different planting densities.The results showed that the reasonable plant density could optimize the harmonious growth of aboveground and underground,increase the root number per plant,single root weight,commodity rate and dry matter accumulation,and accelerate the root expanding velocity.For population,under the plant density of about 52 200 plants per hectare,the relation between individual growth and population yield formation of Taizhong 11 could be better coordinated,and the yield was the highest.
