摘　　要：为了探究生草栽培对柑橘矿质营养及果实品质的影响,以清耕为对照,测定分析了生草栽培条件下椪柑(Citrus reticulata)叶片矿质元素含量及果实品质。结果表明:生草栽培的椪柑叶片钾、磷及硼含量均显著高于清耕,钙含量却显著低于清耕,而生草与清耕两者的镁、硫、铁、锌、铜、锰含量并无显著性差异。生草栽培的椪柑果实可滴定酸含量显著低于清耕,糖酸比显著高于清耕。可见,生草栽培可提高柑橘叶片钾、磷和硼含量及果实糖酸比。In order to investigate the effects of sod culture on mineral nutrition in leaves and fruit quality of citrus, in this study, clean tillage was taken as control, concentrations of mineral elements in leaves and fruit quality of ponkan （Citrus reticulata）under sod culture were determined and analyzed. The results showed that K, P, B contents were very significantly higher in leaves of ponkan from sod culture than from tillage orchard, whereas Cu content was significantly lower than that from tillage orchard, other elements such as Mg, S, Fe, Zn, Cu and Mn had no significant differences between sod culture and tillage orchard. The titratable acidity of fruit was significantly lower from sod culture than from tillage, while the ratio of sugar to titratable acidity of fruit significantly increased in planting grass plot. Thus, it＇s suggested that leaf K, P, B contents and ratio of sugar to titratable acidity of citrus fruit increase from sod culture orchard, compared to the tillage orchard.
