The aim of this study was to investigate the effects of different humic acid fertilizers and biobacteria fertilizers on the yield and quality of Kreisen grapes,and to provide a reliable basis for scientific and rational fertilization for vineyards.The effects of humic acid fertilizer and biological fertilizer on the yield and quality of the grape and the physical and chemical properties of the orchard were studied.The results showed that: 1) The different humic acid fertilizer combined with biological fertilizer increased soil organic matter content,reduced soil pH,increased soil nutrient content; 2) Sugar content of Kerry Sen grape fruit in Humic acid fertilizer treatment was higher than that of control.and,and when the sugaracid ratio was higher,the fruit surface color was more red；3) With application of humic acid fertilizer,the weight of single grape fruit and yield were generally higher,especially for T5 treatment,the single grain weight,ear weight,yield point of view were significantly higher than those of other treatments,and fruit sugar content reached 23.2%,the sugaracid ratio was 26.4∶1,and the difference was significant.Based on the above results,the application of humic acid fertilizer combined with biological fertilizer treatment,which resulted in higher yield and good fruit quality,could be considered in a wide range of promotion.
