摘要
以栽植３年的幼龄温州蜜柑为试材，在低丘红泥沙土上进行了连续３年定位试验。结果表明，３～７年生温州蜜柑在株施绿肥２５ｋｇ（折干）的基础上，株施０．３４ｋｇ纯氮产量最高。配施磷肥能显著增加果实维生素Ｃ的含量，其增幅为６．０４％。同时，施磷还有降低酸度提高糖酸比的趋势，其提高幅度为９．４９％～１２．６３％。长期施用氯化钾可导致果实酸度显著增加，维生素Ｃ含量显著下降，其增幅和降幅分别可达１１．１１％和８．０６％。
Long term experiment was set up in red roam orchard in low hilly area to study theeffect of fertilizer management on 3- year-old satsuma.The results of 3 years experimentshowed that N supplied with 0.34kg per plant based of the application of 25kg green manureresulted in the highest fruit yield.Application of P increased Vc of fruit by 6.04%,as com-pared with the control,decreased fruit acidity and increased sugar/acid ratio by 9.44-12.63%,While continuing applying KCl caused the increasing of avidity and decreasing Vccontent in fruit by 11.11%and 8.06%,respectively.
