不同水肥管理模式对大青葡萄产量及品质的影响

The Impact of Different Water and Fertilizer Management Modes on the Yield and Quality of Daqing Grapes

以当地主栽品种大青作为供试材料,采用随机区组试验方法,设置优化水肥管理模式与常规水肥管理模式两个处理,研究不同水肥管理模式对大青葡萄产量及品质的影响。结果表明,优化施肥模式有助于降低葡萄新梢伸长,减少新梢发生数,增加叶片鲜干比、促进叶面积增加,可实现增产10%以上。优化施肥模式可有效提高大青葡萄果实中的总糖、维生素C、可溶性固形物含量等,有利于均衡糖酸比,改善大青葡萄品质。

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.
