摘要
Abstract
Assessing pod yield and plant phosphorus demand can provide theoretical guidance for fertilization management of high yielding peanut(Arachis hypogaea L.).Following this rationale,a large dataset was collected from field experiments(n=265)across the main pea-nut planting regions of China for a period spanning from 1990 to 2021 to evaluate nutrient uptake behavior of peanut under current optimum fer-tilization management.Across the entire dataset,the results showed that average peanut pod yield and harvest index(HI)were 4 642 kg/hm2 and 0.54.The average peanut phosphorus(P)requirement was 6.45 kg/t.Across five ranges of pod yields(<3,3-<4,4-<5,5-6,and>6 t/hm2),both nutrient uptake and HI increased with increasing pod yield.The P requirement increased with yield,attributed to an in-crease in straw P concentration as P luxury uptake occurs under high pod yield.关键词
