Abstract

Abstract: In order to explicit application and planting density on the winter wheat grouting period of physiological characteristics, the influence of the split plot experiment design using two factors, the‘Ningdong 11’winter wheat grain filling characteristics, grain weight and yield was studied. Results showed that N application has obvious influence on filling duration, especially N4 interchange processing (360 kg/hm²) filling duration increased, but at the same time cause wheat variety; N application on yield notable influence to N3 (270 kg/hm²) with the highest yield. No obvious influence on the filling rate and grain weight. Planting density on the filling duration had no significant effect, but the larger impact on filling rate, grain weight and yield, low density treatment (450×104 spike/hm²), grain weight, the largest filling rate was high, but the yield was relatively low. Medium density (600×104 spike/hm²) grouting speed, the highest yield. Together, in the irrigation area of Ningxia were, when the planting density of 600×104 spike/hm², N application rate of 270 kg/hm² on wheat grouting was the most favorable, and the highest yield, could be up to 12178.36 kg/hm².
