以瓯柑为试材，定期测定果实发育过程中糖和矿质元素含量，探明果实糖和矿质元素的变化规律，为果实营养调控提供理论依据。结果显示，瓯柑果实发育过程中可溶性糖含量呈持续上升趋势，9月2日以后快速积累，至11月22日达到7.70％；还原糖含量呈逐渐增加趋势，11月22日为3.07％；蔗糖含量呈先降后升的趋势，9月2日后急剧增加，至11月22日达到4.40％。瓯柑果实发育过程中N，P，K，S含量呈逐渐下降趋势，Ca，Mg含量呈先增后降趋势，N，P，K积累量呈上升趋势，8月12日至10月12日为快速积累期，此时期积累量分别占到各自总积累量的72.19％，75.99％，66.43％，7月2日至9月22日Ca，Mg，S积累量呈上升趋势，10月12日以后积累量无变化。结果表明，瓯柑果实成熟以积累蔗糖为主，8月中旬前应增施多元复合肥和K肥。

The contents of sugar and mineral elements were measured during development period in Ougan ( Citrus Suavissima Hort.ex Tanaka) fruits, to explore the accumulation trend of sugar and mineral elements and provide theoretical basis for the nutritional regulation .The results showed that during the development of fruits , the soluble sugar content increased continuously , accumulated quickly after Sept .2nd and reached 7.70%on Nov.22nd.The reducing sugar content increased gradually and reached 3.07%on Nov.22nd.The sucrose content decreased in the early phase and increased later , which began to increase rapidly after Sept .2nd and reached 4.40%on Nov.22nd. The N, P, K, S contents decreased , and the Ca and Mg contents increased in the early phase and decreased later . The accumulation of N , P and K elements presented upward trends all along , especially in the rapid accumulation period.The accumulation of them increased and occupied 72.19%, 75.99%, 66.43% of the total accumulation amounts from Aug.12th to Oct.12th, respectively.The accumulation of Ca, Mg and S increased from Jul.2nd to Sept.22nd and did not change after Oct .22nd.The results indicated that Ougan was the sucrose accumulating type , and multi-elements compound fertilizer and K fertilizer application should be increased before mid -August.
