Other claims from this paper (12)
- Association The N fertilizer utilization rate of the pear trees increased with the advancement of the phenological period.
- Observation In the full bloom period the N fertilizer utilization rate was 10.39%, the fastest growing period.
- Observation The N fertilizer utilization rate reached a maximum of 23.62% in the post-harvest stage.
- Observation In the young fruit stage the share of N derived from labeled fertilizer (%Ndff) in the fruit was only 1.02%.
- Observation In the young fruit stage the %Ndff of most new vegetative organs was above 1%.
- Observation The fate of the applied N fertilizer ranked N fertilizer loss > soil residue > tree absorption.
- Observation N loss in the fruit expansion stage was higher, at 3.76 g.
- Observation N loss in the harvest stage was higher, at 3.74 g.
- Observation N utilization rate in the area is low throughout the year.
- Observation The authors state that there is nutrient competition between reproductive growth and vegetative growth in the pear trees.
- Intervention effect The authors state that spring top-dressing can effectively alleviate the nutrient competition between reproductive and vegetative growth.
- Recommendation The authors recommend split fertilizer application and timely supplementation of an appropriate amount of N fertilizer to improve N use efficiency.
