Canonical correlation analysis of soil nutrients and the quality of Beibinghong grape juice
[Objective]To analyze the relationship between soil nutrients and fruit quality of Vitis amu-rensis Rupr.Beibinghong vineyard in the hope of providing reference for selecting suitable cultivation areas for the grage Beibinghong.[Methods]Eight sample sites representing four different habitats of Vitis amurensis Rupr.orchard in Xinjiang were selected to determine fruit quality and soil nutrient factors,and the relation-ships between them were analyzed using typical correlation and redundancy analyses.[Results]The overall coefficients of variation for each indicator of soil nutrients and fruit quality in the eight sample plots ranged from 6.147%to 40.476%and 3.674%to 11.895%,respectively,with the smallest coefficients of variation for pH and total sugar.The relationship between soil available P,available K,cation exchange capacity and fruit total soluble,tannin,totan sugar,total phenols,panicle weight,single fruit weight,individual yield were positively correlated;the relationship between soil alkali-hydrolyzable、cation exchange capacity and fruit an-thocyanin,Single fruit weight,individual yield were positively correlated;the relationship between soil organic matter and fruittotal phenols was negatively correlated;Fruit total acids was significantly and positively correla-ted with soil total nitrogen,and negatively correlated with available K.4 pairs of typical variables explained 75.500%and 94.900%of the information within the soil nutrient and fruit quality groups and 72.100%and 92.100%of the information between the groups;Combined with the coordinate map of typical variables,the ecological area distribution of Yanqi Basin and the northern foot of Tianshan Mountains were relatively concen-trated.[Conclusion]There were significant differences in the content of soil nutrients between the different'Beibinghong'fruit orchards,while the differences between the indicators of fruit quality were small,and the differences between soil pH and total fruit candies were not significant;the effect of soil nutrients on fruit qual-ity was significant and correlated with it.The soil environment in Yanqi County、Wensu County and in Urumqi in the wine grape producing areas of Xinjiang is more favourable to the accumulation of nutrients in Beibing-hong,which has a significant effect on improving the quality of the'Beibinghong'fruit.
