Abstract: Taking Ehima No.28, a new citrus variety as the test material, the fruit quality of 15 orchards in different producing areas in Hubei province was analyzed in 2019, the soil nutrient element content of the orchards was determined. The results showed that there were obvious differences in fruit quality between Ehima No.28 in the test orchard, including single fruit weight, thick skin, transverse diameter and longitudinal diameter. And total soluble solid content (TSS) ranging from 10.23% to 14.13%; The titratable acid content (TA) ranges from 0.47% to 1.06%; The content of vitamin C (Vc) ranged from 27.17 to 48.22 mg/100 g. The solid acid ratio ranges from 11.9∶1~30.1∶1. Test orchard soil also had different nutritional status, soil organic matter (OM), alkaline hydrolytic N and effective Zn content in appropriate range, the content of rapidly-available P and rapidly-available K in most orchards was excessive, all orchard soil effective content of Fe, Mn and Cu effectively were beyond the appropriate range, the content of soil exchangeable Ca and exchangeable Mg is large, the soil effective B and Mo content is generally low; Correlation analysis showed that the fruit of TSS was significantly positive correlation with soil organic matter content, effective B content in the soil with the transverse diameter of fruit weight, fruit and longitudinal diameter was significantly positively related to both, Vc content and exchangeable Ca content in soil was significantly negative correlation, the skin thickness and soil effective Cu content is significantly negative correlation, alkaline hydrolysis N and available K content in soil was significantly positively related to soil organic matter content of OM and exchangeable Mg was significantly positively, this further indicates that the fruit quality of the new variety Ehima No.28 is significantly different under the influence of soil nutritional status, and various elements in the soil also interact with each other.
