1) Nitrogen accumulation and utilization
氮积累和利用
2) Utilization ratio of NO_3~-N
累积氮利用率
3) nitrogen fertilization recovery rate
氮素累积利用率
1.
The pond and field experiments were conducted to research dynamic characters of biomass,nutrients(nitrogen,phosphor,potassium) uptake and nitrogen fertilization recovery rate of cotton after anthesis under different water and nitrogen applications.
灌水使240 kgN/hm2处理棉花(整株、营养器官、生殖器官)生物量和养分快速累积期持续时间缩短、最大累积速率出现时间提前、最大累积速率和累积量增大、氮素累积利用率和产量提高;而使480 kgN/hm2处理棉花营养器官生物量和养分快速累积期持续时间延长、最大累积速率出现时间推迟、生物量和养分最大累积速率及累积量增大、氮素累积利用率提高,而生殖器官相应指标呈降低趋势;灌水对不施氮处理棉花生物量和养分累积各项特征参数影响较小。
4) nitrogen accumulation and translocation
氮素积累和转移
1.
