摘　　要：【目的】研究叶面喷施多肽(肽肥)对葡萄生长的影响,分析多肽单独喷施和与镁配施对森田尼无核葡萄作用效果,筛选提高葡萄品质和产量的施肥方案。【方法】于葡萄坐果期至膨大期进行3次施肥处理,叶面喷施多肽、氨基酸并分别与镁配施,分析不同处理对葡萄叶绿素含量、光合参数、新梢养分含量、产量和品质指标的影响。【结果】叶面喷施0.3%硫酸镁后叶片叶绿素含量显著升高,葡萄果实可溶性固形物和可溶性糖含量增加。施用多肽、多肽与镁配施能促进新梢中氮含量的提高,提升果实的品质。多肽与镁配施后葡萄新梢叶片中镁含量较CK增高了19.01%,净光合速率提高39.84%,产量增高了17.93%。单独施用氨基酸对葡萄品质的提升效果优于氨基酸与镁混合施用。【结论】多肽与镁配施对促进葡萄光合作用、提高葡萄果实品质及产量效果最佳。【Objective】To explore the effect of foliar spraying of peptides on grapesgrowth,reasonably supplement nutrients and magnesium for grapes,study the effect of spraying peptides alone and combined with magnesium,and screen fertilization schemes that can improve grape quality and yield.【Methods】Three fertilization treatments were carried out from fruit setting stage to expansion stage and polypeptide and amino acid were sprayed on the leaves and combined with magnesium respectively.The effects of different treatments on chlorophyll content,photosynthetic parameters,nutrient content of new shoots,yield and quality indexes of grapes were analyzed.【Results】After spraying 0.3%magnesium sulfate on the leaves,the content of chlorophyll in leaves increased significantly,and the content of soluble solid and soluble sugar in grape fruits increased.The application of polypeptide,polypeptide and magnesium could promote the increase of nitrogen content in new shoots and improve the quality of fruits.Compared with CK,the content of magnesium in grape shoot leaves increased by 19.01%,the net photosynthetic rate increased by 39.84%,and the yield increased by 17.93%.The effect of single application of amino acid on grape quality was better than that of mixed application of amino acid and magnesium.【Conclusion】It can be concluded that the combined application of polypeptide and magnesium has the best effect on promoting grape photosynthesis,which improves grape fruit quality and yield.
