不同土壤类型冰糖橙园土壤中微量元素养分特征及其对果实品质的影响
Characteristics of medium and trace nutrient elements and their impact on fruit quality of Citrus sinensis(L.)Osbeck orchard with different soils
摘要
Abstract
This study investigated the relationships among medium and trace elements content as well as fruit quality from different soil types as to provide a scientific basis for redress of nutrient in citrus orchards.Soils and fruits from 109 Citrus sinensis(L.)Osbeck orchards sampled from red soil,purple soil and paddy soil in Hunan Province at fruit maturity stage were examined with chemical and statistical analysis to evaluate soil pH,organic matter content,available medium and trace elements,and fruit quality parameters.Results showed that red soil citrus orchards have higher soil pH(4.95)than that of purple soil(4.75)and paddy soil(4.35),while organic matter content in paddy soils is significantly higher than that in purple soils and red soils by 28.2%and 38.9%,respectively(P<0.05).Exchangeable Ca and Mg showed no significant differences between citrus orchard on soil types.High variability(CV=100.9%)of exchangeable Ca was observed in red soil.Paddy soils exhibit significantly higher levels of available S(57.5%and 83.4%higher than red soils and paddy soils,respectively)and available Zn(45.6%and 80.0%higher than red soils and purple soils,respectively,P<0.05).Whereas no differences were observed for Fe,Mn,Cu,or B.No significant differences in fruit quality were observed between red soil and paddy soil orchards.However,purple soil orchards exhibited higher fruit shape index(0.98)and soluble solids percentage(14.2%)compared to paddy and red soils citrus orchard,but lower solid-acid ratio(22.5)and Vc content(27.5 mg·100 g-1).Correlation analysis revealed organic matter was positively linked to available S,Fe,Cu,Zn,and B,while soil pH,available S,and B were key factors affecting fruit quality.The heterogeneity of available medium and trace elements in citrus orchard was strongly linked to soil pH and organic matter.In red and paddy soil orchards,fruit quality can be enhanced by enhancing soil pH and supplementing micronutrients,while purple soil requires measures to prevent excessive accumu-lation of trace elements through orchard management.关键词
