| Abstract: | Field experiment showed that application mode of nitrogen fertilizer on the Aeolian soils could be simulated by equation Y=ax2+bx+c.By using this mode,we calculate the highest benefit application rates for high yielding maize variety 'Xianyu 335' is 146.8kg/ha,and crop yield increases and income increases is 67.8% and 3213 Yuan RMB/ha,respectively. |
| Keywords: | Aeolian soils Maize Application mode of nitrogen fertilizer The highest benefit |
