| Abstract: | In the mutual actions of natural, adaptable,sufficient soil moisture and none,medium, high fertilizer application,the effects of soil water and fertilizer coupling on the efficient leaf area and grain yield of spring wheat are studied. The result shows that the efficient leaf area is positive correlation with fertilizer application level ,the highest grain yield (3713kg/hm2) is obtained in appropriate soil water and high fertilizer application. |
