Abstract：To discuss the slowing effects of nitrogen (N ) application modes on peanut continuous cropping obstacle,different basal/topdressing ratios were designed to investigate agronomic characters, photosynthetic characteristics,dry matter and yield for continuous cropping peanut as affected by N application modes.The results show that,at the same N rate,N fertilizer postponing increased effective photosynthetic area during the process of pod maturation,in favor of improving yield component factors, and increased net photosynthetic rate,chlorophyll content,dry matter and peanut yield.Compared with single basal fertilization,reasonable basal/topdressing cooperated fertilization met N needs much better for continuous cropping peanut growth,ensured fertilizer sufficiency during the whole growing stage,and further increased peanut yield,in which the yield under 2 5% N basal fertilization and 7 5% N topdressing at flowering and pegging stage was the highest,3 906.7 kg/ha,by increment of 21.3% compared with total N basal fertilization.
