| Abstract: | Through the rotating,regressive and perpendicular experiment and study of the effect of wheat yield between different fertilizer quantity and density.The wheat yield and the relation between the general regressive models as well as the 6 filial models of fertilizer quantity and density have been created.It reveals to what extent the density and fertilizer can affect wheat yield.The maximum of wheat yield in theory has been found.$$$$ |
| Keywords: | rotating regressive and perpendicular experiment wheat model |
