摘　　要：通过田间试验,研究施用炭基缓释花生专用肥对砂姜黑土夏花生干物质积累及产量的影响。结果表明,不同施肥处理各器官干物质质量在不同生育时期的变化趋势基本相同,随着生育期的推进,根茎的干物质质量呈"S"型变化趋势、叶干物质质量呈现先增后降的变化趋势,荚果干物质质量随着生育期的推进不断增加,并在成熟期达到峰值。从苗期到成熟期,各处理花生植株干物质累积总量为逐渐增加的趋势,干物质累积速率呈现"慢—快—慢"的"S"型动态变化趋势。产量形成期对照、复合肥和炭基肥处理的干物质累积量迅速增长,该时期累积总量分别占全生育期干物质总量的59.24%、57.87%和65.88%,且累积量和累积速率均以炭基肥处理最高,各处理间差异显著。炭基肥处理的花生功能叶SPAD值在不同生育期均高于复合肥和对照处理,荚果产量为4366.01kg·hm^(-2),较对照和复合肥分别增产29.58%和11.78%,差异显著。Field experiments have been conducted to study the effects of charcoal-based slow release peanut specific fertilizer on dry matter accumulation and yield of summer peanut in lime concretion black soil.The results showed that the variation trend of dry matter of various organs at different growth stages were basically similar under different fertilization treatments.The root and stem dry matter showed a tendency of S type with the advance of the growth stage,the mass of leaf dry matter increased initially and then decreased in different growth stages,pod dry matter mass increased with the growth period and reached its peak at mature period.From the seedling stage to the mature stage,the total amount of dry matter accumulation of peanut plants increased gradually,and the rate of dry matter accumulation showed a slow-fast-slow trend of S type.The dry matter accumulation of CK,compound fertilizer and charcoal-based slow release peanut specific fertilizer treatments increased rapidly during the yield forming period,and the accumulative amount of dry matter in this period accounted for 59.24%,57.87%and 65.88%of the total dry matter during the whole growth period,respectively,and the accumulative amount and accumulation rate were the highest with the charcoal-based peanut specific fertilizer treatment.Significant differences among treatments were found.The SPAD value of functional leaves of peanut treated with charcoal-based slow release peanut specific fertilizer was higher than that of compound fertilizer and CK during different growth stages,and the pod yield was 4366.01 kg/hm 2,which was 29.58%and 11.78%higher than that of CK and compound fertilizer,respectively,and the difference was significant.
