The high-yielding mechanism of sweet potato variety Tianfeng No .1 was explored through comparative researches on the main physiological characteristics between this variety and the control variety Jinshan 57 under high-yielding ecological culti-vation conditions .The results indicated that Tianfeng No .1 grew faster than Jinshan 57 at the earlier growth stage , and maintained higher efficiency of photosynthetic production in the whole growth and developmental period ;Tianfeng No.1 had large sink capaci-ty, strong ability to accumulate assimilation matter in its tuberous roots , and high economic coefficient;these were the physiological basis that Tianfeng No.1 formed high yield.This variety is characterized by high quality , high yield, wide adaptability, strong dis-ease resistance , easy cultivation , etc., and it has a certain extension and application value .
