Abstract:: The soi l celluloly tic enzyme activ ty of soy bean continuo us cro pping in dif ferent continuouscro pping years and di fferent g row th stages w as studied by field experiment s.The result s show tha t the chang e o f sowing time i s nea rly co nsi stent wi th ma ture periodand the soil celluloly tic enzyme activ ity is the low est in soy bean fo llowing so ybean for 2y ea rs. In co nt rast wi th i t, the soil celluloly tic enzyme activi ty of po dding stage i s thehighest in soybea n fo llowing so ybean fo r 2 yea rs and i t is almost higher po dding stag ethan tha t of sowing time, mature period. At last, by the co rrelatio n a nalysi s, w e foundthat the chang e o f soil celluloy tic enzyme activi ty in sow ing time, mature period is significa nt ly po stiv e co rrelatio n wi th soi l o rganic carbo n and pH.
