Abstract:

In order to explore the effects of amino acid water-soluble fertilizer on grape yield and quality,the full-fruit Zaohebao grape was used as the experimental material,three treatments were set up:conventional fertilization (CK);increased application of organic fertilizer (OPT);organic fertilizer + amino acid water soluble fertilizer treatment (OPT+AA),the effects of exogenous amino acids on grape yield,growth,quality and soil nutrient content were studied.The results showed that compared with CK,grape yield decreased by 14.17% under OPT treatment and 7.50% under OPT+AA treatment,but were not significant.Compared with CK,partial productivity of fertilizer treated with OPT and OPT+AA increased significantly.Partial productivity of N,P2O5 and K2O treated with OPT+AA increased significantly by 73.44%,85.01% and 85.01%,respectively.OPT+AA significantly increased total sugar by 8.09%,soluble solids by 1.32 percentage,sugar-acid ratio by 38.80%,and the titratable acid content by 0.16 percentage.The nutrient content of shoots was significantly increased by 24.73% in OPT+AA,total phosphorus content and total potassium content were significantly increased by 24.73%.In addition,OPT and OPT+AA treatments did not inhibit plant growth,but could effectively reduce the leaching of available nutrients and increase the nutrient content in the root domain.In summary,reducing and increasing the application of organic fertilizer had no significant effect on grape yield,but could reduce the leaching of available nutrients and significantly improve the partial productivity of fertilizer.The application of amino acid water-soluble fertilizer could promote nutrient absorption in plants,improving grape yield and fruit quality.

Key words: Grape, Amino acid water soluble fertilizer, Organic substitution, Yield, Quality
