Effect of different irrigation methods on growth,yield and quality of little white apricot

To explore water-saving methods in South Xinjiang,with 6~7 year old little white apricot as material,an experiment was conducted in Kuche of Xinjiang during 2009~2010 to study the effect of controlled alternative irrigation on growth,yield and quality of little white apricot.The results were as follows: The watewr amount in controlled alternative irrigation was reduced by 50% compared with that in conventional furrow irrigation,and reduced by 75%,compared with that in flooding irrigatuion;This method significantly inhibited the trees' new shoot,but had no evident effect on flowers' fruit-bearing rate,fruit hardness and Vc content;whereas soluble solids content of fruit and acid content were markedly improved.The yield of no film controlled alternative irrigation was reduced significantly,while other treatments had no observably effects on yield.It was suggested that the optimal irrigation scheme would be film controlled alternative irrigation.
