Differential analysis of soil factor affecting the formation of fruit quality in different Myric rubra varieties
Using soil from 8 main production areas of Myric rubra in Zhejiang Province and two main varieties,Dongkui and Biqi,as experimental materials,correlation analysis was conducted between soil fertility and corresponding fruit quality indicators of different Myric rubra varieties.The main soil factors affecting the formation of fruit quality of different Myric rubra varieties were screened.Thirteen soil fertility factors and 18 fruit quality indicators were measured in the Dongkui and Biqi orchards,and correlation analysis was conducted.It was found that there were 94 significant correlations between soil fertility factors and fruit quality indicators in Biqi.Among them,soil organic carbon content,organic matter content,total nitrogen content were significantly positively correlated with fruit hardness,glucose content,vitamin C content,total flavonoids content,and total phenols content.Increasing the above indicators appropriately can improve fruit hardness,quality,and storage tolerance.There are 33 significant correlations between soil fertility factors and fruit quality indicators in Dongkui,among which available potassium content and total potassium content are significantly positively correlated with glucose content,vitamin C content,total flavonoids content,total phenols content,and total amino acids content.Increasing these indicators can appropriately improve fruit quality.The significant correlation between soil fertility and fruit quality in Dongkui was less than that of Biqi.Based on years of production experience,it is speculated that the formation of Dongkui fruit quality requires less soil fertility than Biqi,and requires more water,light,temperature,pruning and other factors than Biqi.
