Abstract
In order to grasp the phosphate needs of the law of the fruit of wine grapes in the eastern foot of Helan Mountain Sandificational,a field experiment combined with lab analysis was conducted to study the effect of phosphate fertilizer application amount on the grape growth,nutrient uptake,yield and quality,as well as economic benefits of 3 years wine grape in sandy soil at eastern foot of Helan Mountain of Ningxia.The results showed that within a certain range with the enhanced application rate of phosphate fertilizer,the length of new branches,leaves weigh,the contents of N,P,K in leaves,as well as the yield of the three years wine grape were significantly increased along with the increased phosphorus application rate less than 225 kg/hm2.However,further increased phosphorus led to decrease of branche length and yield.The maximum application rate of phosphorus for the 3 years wine grape was 266.67 kg/hm2.The optimum application amount of phosphorus was 233.33 kg/hm2.
