| 摘 要： | 以枳砧温州蜜柑为试材,进行了长期定位施用磷、钾、镁肥试验。连续6年的试验结果表明,施用磷、钾、镁肥均有明显增产效果,并能提高叶片和果皮中相应元素的含量。其中,以在施用氮磷钾肥的基础上增施镁肥的增产优质效应最佳。长期施用氯化钾导致果实维生素C含量降低,总酸量增加。贮藏试验结果表明,果实耐贮性与施钾成正相关,与施镁成负相关,施磷对果实耐贮性亦有不利影响。

| Abstract: | Seven years old satsuma mandarins on trifoliate orange rootstocks were used for long-term fertilization test of superphosphate, potassium chloride and magnisium sulphate in red loam soil. The results for six years on end showed that the application of P,K , Mg fertilizers could significantly increased the yield and increased the P, K , Mg contents in leaf and peel. The best effect of additional fertilization of Mg after that of N,P and K on yield and fruit quality was obstained. But long-term application of potassium chloride decreased the vitamine C content and increased total acid content. The results of storage trial showed that the storage property positively correlated with K fertilization but negatively with Mg. P fertilization was unfavorable to it. |
