Effect of Different Irrigation Water Quantity and Drip Tape Interval on Growth and Yield of Grapes in Turpan

The experiments of drip irrigation for Turpan grapes,with the irrigation quota of 720,850and 960mm and the drip tape interval of 40and 60cm,were conducted in 2013to monitor and analyze the growth index,water consumption and yield data of the grapes.The results showed that the growth indexes and yield of the grapes under the condition of drip tape interval of 60cm were better than that under the 40cm interval;the water consumption of grape in different irrigation quota treatments all changed from low to high then dropped,the water consumption and water consumption intensity increased with the increase of irrigation water quantity,in which the water consumption quantity at the grape berry enlargement stage was the largest,followed by other berries mature and mature vines,shoots growing,flowering and budding;the grape yield and water use efficiency of the W2treatment with 850mm irrigation quota were the largest,which is better than those of the W3treatment with 960mm irrigation quota irrigation,the increase of irrigation quantity within a certain range could increase the grape production;comprehensively considering the factors of yield and water use efficiency,the drip tape laying interval was decided as 60cm and the irrigation quota was decided as 850mm.
