Abstract:

Mathematic model to describe the relation betw een y ields and four cultivation measures w as set up inthe main soy bean productions area of Inner Mongolia , taking Mengdou 5 as experiment material under dry farmingcondi tion , through studying the relation betw een different amount of N 、P2O5 、K2O applied , different seedingrates , four cultivation measures and yield consti tuent s;Acco rding to optimum analyzing the model , the crossscheme of optimum ag ricultural cultivation measures that the goal yields was above 175kg/667m2 was put forward , namely the density w as 2 .05 -2 .19 ×104 plants/667m2 , amount of N , P2O5 , K2O w as 4 .0 -4 .7kg/667m2 , 4 .05 -5 .5 kg/667m2 , 3 .7 -4 .4 kg/667m2 rspect ively .It had been proved that the model and the opt imumscheme were feasible by experiments , and had signif icant theoretical meaning and applied v alue .Thechange curve of seeds/plant , seeds/pod 、100 -seed weight and yield all took on sing le -peak curve along with theincreasing density and fertilization , besides the pods/plant increases along w ith the reduction of density .
