Abstract
A study was conducted on the effects of three kinds of foliar fertilizer on the yield and quality on the Red Globe grape and Munage grape,with a view to provide theoretical basis and practical guidance for effective foliar fertilization in the grape production.The result showed that spraying Amino acid chelated Calcium liquid fertilizer,humic acid liquid fertilizer and balanced nutrients at different growth stages of the grapes could significantly increase the chlorophyll content(SPAD value),yield,soluble solid content and the reduced ascorbic acid,and it could also significantly reduce the titratable acid content,in which the effect of taking four times amino acid chelated calcium liquid fertilizer on Red Globe grape and Munage grape could get the best effect,and the yield increase was respectively 8.50% and 17.15%,and the quality of grape treated by acid chelated calcium liquid fertilizer was also better than other two kinds of spray fertilizer.
