| Abstract: | The optimal compound design(311B) was used to conduct field trail on different ration of Nitrogen,Potassium,Magnesium nutrition of tobacco.The result indicated that the yield and output value of tobacco were affected respectively by the different allocation of N,K 2O,Mg to the different extent.Some optimum allocation schemes of N,K 2O,Mg in the test,were obtained by realityimitaling and optimumsearching with computer.Yield scheme ,N 86 40 kg/hm 2,K 2O 492 45 kg/hm 2,Mg 19 35 kg/hm 2;Output value scheme N 72 15 kg/hm 2,K 2O 523 50 kg/hm 2, Mg 18 00 kg/hm 2;Average price scheme,N 52 20 kg/hm 2,K 2O 417 75 kg/hm 2,Mg 13 20 kg/hm 2;Synthetical scheme,N 70 25 kg/hm 2,K 2O 477 90 kg/hm 2,Mg 13 10 kg/hm 2. |
