Abstract:
The object o f thi s study i s to verify tha t there is vig oro us supersession ofnew and old roo ts in soy bean va rio us g row ing stag es. Thro ugh the combining analysiso f the data of 3 ex perimental methods ( So lution culture, reduction of manganese oxide,square dif ferential value ) , i t i s co nfi rmed that in soy bean exist s a process ofsupersession o f new and old roo ts f rom seedling to po d fi lling stages, a nd there a re atleast 6990. 4cm of roo t s in leng th and 255. 8 no dules in 0. 0175m3 which sustain decayf rom June to Aug ust. It show s that the supersession of new a nd o ld roo t s i s animpo rtant link in the mecha nism of soy bean fer ti li zing soil.
