Correlation Analysis Between Fruit Quality of Majia Pumelo and Soil Nutrients,Leaf and Fruit Mineral Nutrients
摘要
Abstract
Using canonical correlation analysis and multivariate analysis in the SPSS software,the main af-fecting factors of soil nutrients,leaf and fruit mineral nutrients were find out after an investigation of soil nutri-ent,leaf and fruit mineral nutrients,fruit qualities in Majia pomelo orchards of 5 townships in Guanfeng,Jiangxi Province.The result showed that multivariate analysis was suitable for this test and there were significant differ-ences in soil nutrients,leaf and fruit mineral nutrients among different orchards.The correlations between soilnutrients,leaf and fruit mineral nutrients and fruit qualities were strong.The fruit soluble solids had positive correlation with available Cu in soil,and negative correlation with P,K in leaves and Mn,Zn in fruits.The ti-tratable acid had positive correlation with available Mn in soil,Mg in leaves and Fe in fruits,and negative cor-relation with soil organic matter (OM).The Vc had positive correlation with Cu in fruits,and negative correla-tion with available Fe in soil and P in leaves.The total sugar had positive correlation with OM,and negative correlation with available Fe in soil,correlation with OM,and negative correlation with available Fe in soil,K in leaves and Mn in fruits.The fruit mass had negative correlation with available Zn in soil,N,Zn in leaves and Cu in fruits.The pericarp thickness had negative correlation with Zn in leaves and Cu in fruits.The juice yield had positive correlation with pH and available Cu in soil,N in leaves and Fe in fruits,and negative correlation with Zn in fruits.Using a combination of soil nutrients,leaf and fruit analysis could better reflect the fruit quality.Ad-justing the pH to 5.5-6.5 and increasing the content of OM in soil and Ca,Zn in leaves could promote the pro-duction of Majia pomelo with high content of total sugar and Vc and low content of acid.关键词
