Scientific research shows that the sweet potato seedling twice reduced stems and leaves 16.3%, 28.3% reduction in root tuber; Transplanted 4 to 5 times the stems and leaves 40.8% ~ 50.6%, 17.5% ~ 28.3% reduction in root mass. Therefore, the more the number of transplanting, the greater the rate of decrease.
