BACKGROUND: Foliar fertilizer adjuvant is a fertilizer adjuvant that can improve the efficiency of plant leaf nutrient absorption. It is an effective means to reduce fertilizer usage and protect the environment, and plays an important role in agricultural production. However, under drought stress, traditional foliar fertilizers are susceptible to photolysis and evaporation loss, which affects the efficiency of nutrient absorption. This experiment used the 10-year-old grape 'Zitian Seedless' planted in the Wuwei area of the Hexi Corridor as the test material, focusing on foliar fertilizer adjuvants, and through its synergistic effect, explored the effects of potassium dihydrogen phosphate combined with different foliar fertilizer adjuvants on leaf endogenous hormones and fruit quality. METHOD: This experiment had a total of six treatments: CK (potassium dihydrogen phosphate), T1 (potassium dihydrogen phosphate + ethylated and methylated vegetable oil), T2 (potassium dihydrogen phosphate + silicone), T3 (potassium dihydrogen phosphate + green citrus oil), T4 (potassium dihydrogen phosphate + sodium nitrophenolate aqueous solution), T5 (potassium dihydrogen phosphate + triacontanol solution + benzylaminopurine). The effects of different foliar fertilizer adjuvants on grape fruit quality and endogenous hormones in leaves were explored through a solar greenhouse experiment. RESULTS: Different foliar fertilizer adjuvants can improve the quality of fresh grapes, and each treatment s...
