The Impact of Different Water and Fertilizer Management Modes on the Yield and Quality of Daqing Grapes
To study the effects of different water and fertilizer management modes on the yield and quality of Daqing grapes,the locally cultivated variety Daqing was used as the test material,and a randomized block experiment was conducted to set up two treatments,including optimized water and fertilizer management mode and conventional water and fertilizer management mode.The results showed that optimizing the fertilization mode could be helpful to reduce the elongation of grape new shoots,decrease the number of new shoots,increase the fresh to dry ratio of leaves,promote the increase of leaf area,and achieve a yield increase of more than 10％.Optimizing the fertilization mode could effectively increase the total sugar,vitamin C,soluble solids and other contents in Daqing grape fruit,which was beneficial for balancing the sugar acid ratio and improving the quality of Daqing grapes.
