Abstract:

In order to study the application method of humic acid on grapes and find out the optimal proportion of carbon such as humic acid instead of organic fertilizer,the plot experiment was carried out with simple chemical fertilizer fertilization mode as control(CK treatment)for two consecutive years.Based on farmers' fertilizer practice(FFP treatment),3 ratios of carbon such as humic acid instead of organic fertilizer were set:10% carbon substitution(T1 treatment),20% carbon substitution(T2 treatment)and 30% carbon substitution(T3 treatment).Their effects on grape yield,quality and soil nutrients were studied,and the optimal substitution ratio was screened by principal factor analysis.The results showed that the yield of T2 treatment was the highest for two consecutive years,but there was no significant difference between T2 and T3 treatment.Single cluster weight and single fruit weight in T1,T2,T3 treatments were significantly higher than those in CK treatment,but there was no significant difference between FFP treatment and T1,T2,T3 treatments;on the whole,the contents of soluble solids,soluble sugar,titratable acid and vitamin C in humic acid treatment instead of organic fertilizer were better than those in other treatments.Through correlation analysis,soil available potassium,organic matter and acid phosphatase were positively correlated with grape yield.Available phosphorus,available potassium,organic matter and acid phosphatase in soil were very significantly correlated with soluble solids,soluble sugar and vitamin C content of grape.Regulation of these soil indexes was the way to increase grape yield and quality by replacing organic fertilizer with humic acid;through principal factor analysis,there were 2 principal factors with eigenvalue greater than 1 in 2019 and 2020,the cumulative contribution rate of variance of 2 principal factors reached 88.864%-91.470%,and T2 treatment was the highest comprehensive score for two consecutive years.On the whole,carbon such as humic acid instead of 20% organic fertilizer was the optimal proportion.
