| Abstract: | This test was to study the regression model about the planting density and the matching application NPK by optimum compound design in hybrid maize yumeitou 168 seed production. Then analysis various factors to action effects in seed yield, modeling by computer, the results indicated that the density was 80100 plants/hm^2 and the volume of fertilizer delivery was N of 269.91kg/hm^2, P205 of 100.78kg/hm^2,K20 of 187.9kg/hm^2, it can obtain the maximum yield. The density was 79360 plants/hm^2 and the volume of fertilizer delivery was N of 161.55kg/hm^2, P2O5 of 66.9kg/hm^2,K2O of 171.15kg/hm^2, it can receive the planting plans with maximum profit that deduct the cost of the fertilizer. |
