Abstract:
Taking three-year-old wine grape ‘Cabernet Sauvignon’ as test material at the eastern foot of Helan Mountain,farmer tradition was used to set six gradient nitrogen fertilizers of namely pure nitrogen application amount 0 kg?hm-2,120 kg?hm-2,240 kg?hm-2,360 kg?hm-2,480 kg?hm-2 and 600 kg?hm-2 to research the effects of nitrogen fertilizer application on the beginning growth and yield,quality of wine grape.The results showed that nitrogen fertilizer could significantly promote the occurrence of plant height,shoots length,axillary shoots number,nitrogen application amount was 480 kg?hm-2 made SPAD value for 4311,and 314 μmol?mmol-1 stand for enhancing the utilization of water effectively.It was concluded that the nitrogen application amount for maximum yield was 39875 kg?hm-2 by the simulation equations,when nitrogen application amount exceed 480 kg?hm-2 showed the growth decline,at the same time reducing sugar acid ratio.Nitrogen application amount 360 kg?hm-2 significantly improved the anthocyanins,soluble sugar,total phenols,and improved the quality of wine grape.
