Abstract: In order to evaluate performance of slow/controlled release fertilizer coated and felted by nano-materials, yield and quality of winter wheat and summer corn were determined through the 3-year and 6-season field experiment in winter wheat-summer corn rotation. The results showed that grain yield and protein were improved in some degree, but protein content was increased insignificantly, and soluble sugar content was decreased by slow/controlled release fertilizer coated and felted by nano-materials compared with NPK chemical fertilizer. It was effective to use slow/controlled release fertilizer coated and felted by nano-materials to improve wheat yield and quality but the effects were different.
