Effect of Irrigation on Growth,Yield and Quality of Wine Grape in Eastern Foot of Helan Mountain

In the eastern foot of Helan Mountain,the grape planting has the problems of low water use efficiency of flood irrigation,low and unstable production and poor fruit quality.The field experiments are conducted with traditional furrow irrigation and drip irrigation with different water quantity and the growth,yield and quality of wine grape under each treatment are measured.The results show that the length of new shoot increases under drip irrigation and that under double tube drip irrigation is the longest;the fresh weight under drip irrigation is significantly higher than that under furrow irrigation;the fresh weight under double tube drip irrigation is further significantly higher than that under single tube drip irrigation;drip irrigation has a trend to accumulate leaf total nitrogen and,leaf total nitrogen significantly improves when compared to furrow irrigation;Double tube drip irrigation can significantly increase fruit soluble solid content material and the soluble sugar content;Single tube drip irrigation processing can reduce total acidity of fruit and increase sugar acid ratio;both Single and double-drip irrigation have significant increase on yield compared with furrow irrigation.
