Abstract
The field experiment was executed with peanut TJ in the Experimental Station of Agricultural Ecology Institute,Fujian Academy of Agricultural Sciences to study the effects of N fertilizer application amount on the photosynthetic characteristics,yield and kernel quality of dual-purpose peanut.The results showed that the yield of peanut and peanut vine were increased by low level N application and decreased by high rate,and reached the highest at applying N 300 kg/hm2 level.The peanut yields was 2.2% greater than that of no fertilization.The peanut vine yields was 86.0% greater than that of no fertilization.Photosynthetic characteristics study showed that the photosynthetic rate of peanut function leaf was increased by low level N application and decreased by high rate,and reached the highest at applying N 300 kg/hm2 level,while stomatal conductance and transpiration rate decreased gradually with the increase of nitrogen fertilizer.Quality with increase of nitrogen application rates,crude protein content of peanut vine was increased,but higher nitrogen rate improved the quality of peanut seedling.300 kg/hm2 N application was chosen to give the highest yield and the good quality in the peanut vine.
