【Abstract】 The field test on DK1 maize with different density and different amount of applying fertilizer indicates that the output difference reaches the extremely remarkable level under condition of the different density and different applying fertilizer amount condition. As for comprehensive output and economic benefits, it is best to apply about 522 kg nitrogen by each hectare. The output raises as the density increases with the most suitable density should keep in about 64500 for each hectare.更多还原
