Abstract:
With slow/cont rolled release fertilizer , dry matter accumulation/parti tioning and nut rient s absorpt ionand yield variation in the g row ing period of soy bean were investigated in pot experiments .The result s show edthat dry mat ter accumulatio n during the g row ing period in all t reatments are higher than that of cont rol , especiallythe LP -40 and LP -70 ;how ever , only LP -40 , LP -70 and LP -SS100A treatments are higher thancont rol af ter pod -set ting .The controlled release fertilizer wi th short releasing time have less effect on nitrogenabsorption , w hile the long time one may reduce the ni trogen absorpt ion at the earlier stage .How ever controlledrelease fertilizers in general can increase the absorption of K+to a certain extent , but have no effect on absorptionof PO43 - .LP -SS100A can increase productivity by 21 .9 %, LP -70 and LP -180A can increase productivity by 13 .1 % and 12 .2 % respectively .
