Abstract：The effect of combined use of straw and nitrogen fertilizer on wheat yield , thousand-kernel weight, nitrogen use rate and nitrogen benefit were studied by field experiments .The results indicated that the thousand-kernel weight was the highest as 39 .4 g when treated with nitrogen at the ratio of basal to dressing as 6∶4.The yield was the highest when treated by nitrogen at the ratio of basal to dressing as 7∶3, and then the one at the ratio of 6∶4 , but there were no significant differences between them .The nitrogen use rate and nitrogen benefit were the highest when treated by nitrogen at the ratio of basal to dressing as 6∶4 .So under the test conditions , the best treatment was nitrogen at the ratio of basal to dressing as 6∶4 combined with full corn straw returning , followed by the treatment with nitrogen at the ratio of 7∶3 .Under the condition of straw retur-ning, optimally increasing nitrogen amount at earlier stage could promote wheat growth and improve nitrogen u -tilization.
