| Abstract | In view of the influence of straw returning interval time on soil particle size and corn yield, in order to determine the interval time of straw returning to the field, a study on the influence of straw returning to the field on soil particle size and corn yield was put forward. The experiment of straw returning to the field every other year, straw returning to the field continuously, and straw returning to the field continuously with nitrogen fertilizer was made. The results showed that although there was a trend of increasing corn yield and 100 grain weight in the year of straw returning, the difference was not significant; in the fifth year of straw returning, the effect of increasing corn yield and 100 grain weight was obvious, the increase range of corn yield was 3.07 similar to 11.69 %, the increase of 100 grain weight was 1.41 similar to 5.20 %, the effect of continuous returning and returning every other year on yield and 100 grain weight was not significant, but increasing nitrogen had a significant increase. The yield and 100 grain weight increased by 5.51 % and 3.65 %, respectively. The continuous return of straw to the field, the return of straw to the field every other year, and the increase of nitrogen had no effect on the seed yield of maize. |
