Effects of Different Organic Fertilizers on Wine Grape Yield and Quality in Sanggan River Basin
'Chardonnay'grapes were used as the test material,and five different organic fertilizer treatments were set up in a field randomized block design(D-l,applying German BioElite fertilizer 1.8 t·hm-2;D-2,applying German BioElite fertilizer 5.4 t·hm-2;D-3,applying German BioElite fertilizer 18.0 t·hm-2;SA,applying Sanan bio-organic fertilizer;YF,applying rotted goat feces organic fertilizer).By measuring fruit yield and related quality indexes at maturity stage,using principal component analysis and membership function comprehensive evaluation method,in order to provide reference for the upgrading of grape industry technology in Sanggan River basin.The results showed that the overall fruit quality of'Chardonnay'grapes applied with German BioElite fertilizer at 5.4 t·hm-2 was the best,with the yield of 1.50 kg.The contents of total phenols,total flavonoids,total flavan-3-ols and total tannins were 18.23,8.73,7.74,8.15 mg·g-1,respectively.At the same time,it had the characteristics of high sugar and high acid,the reducing sugar content and titrable acidity were 243.73 g·L-1 and 5.11 g·L-1 respectively,which was conducive to the production of high-quality wine,so it was recommended to promote the use in the wine viticulture management in the Sanggan River basin.
