缓释肥侧位深施对花生产量及养分利用的影响
Effects of Side Deep Application of Slow-Release Fertilizer on Peanut Yield and Nutrient Utilization
摘要
Abstract
To investigate the effects of different fertilization treatments on peanut yield and nutrient utilization,five treatment groups were established in this study as CK(no fertilizer),T1(conventional compound fertilizer,surface broadcasting;450 kg/ha basal+150 kg/ha topdressing),T2(conventional compound fertilizer,side deep application at 10 cm;450 kg/ha basal+150 kg/ha topdressing),T3(peanut-specific slow-release fertilizer,surface broadcasting;450 kg/ha),and T4(peanut-specific slow-release fertilizer,side deep application at 10 cm;450 kg/ha).Growth traits,yield and its components,dry matter mass,and whole-plant nitrogen(N),phosphorus(P),and potassium(K)contents were measured.Additionally,peanut nutrient accumulation and allocation rates,as well as agronomic efficiency were calculated.The results indicated that all fertilization treatments significantly promoted peanut growth,increased yield,and improved agronomic efficiency.Compared to conventional compound fertilizer,slow-release fertilizer significantly enhanced peanut yield and related traits.T4 achieved the highest yield(5,730 kg/ha),followed by T3(5,574.67 kg/ha).Compared to surface broadcasting,side deep application significantly increased dry matter accumulation,N/P/K uptake,and agronomic efficiency.Among the four ferti-lization treatments,T4 exhibited significantly higher growth traits,yield and related traits,nutrient accumulation and allocation rates,and agronomic efficiency than the other treatment groups.Therefore,the side deep application of 450 kg/ha peanut-specific slow-release fertilizer can synergistically improve peanut yield and nutrient use efficiency.关键词
