通过对重庆开县12个主要柑橘果园采集的67个叶样的氮、磷、钾、钙、镁、硫、铁、锰、锌、铜、硼等11种营养元素进行分析测定，结果表明，柑橘园的中叶片普遍氮偏高，缺锌、钾、镁。氮过量占77%，磷过量占37%，缺钾占75%，缺锌占95.5%，缺锰占40%，缺镁占62%。根据叶片营养丰缺状况配方施肥，调整开县柑橘施肥措施，重点控氮、补钾、补锌、补镁、补锰，从而全面提高开县柑橘产量和质量。

Contents of 11 kinds of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, manganese, iron, copper, zinc and boron in 67 leaf samples from Chongqing Kaixian 12 main citrus orchard were analyzed.The results show that, Common citrus orchard leaf has higher nitrogen, but is lack of zinc, magnesium, potassium.Excess nitrogen accountedfor 77%, excess phosphorus accountedfor 37%, potassium deficiency accounted for 75%, Zinc deficiency accounted for 95.5%, Manganese deficiency accounted for 40%, Magnesium deficiency accounted for 62%.Adjust the fertilization measures of Kaixian Citrus, according to the nutritional content of leaves, the key measure is control of nitrogen and supplement of potassium, zinc, magnesium, manganese.In order to improve the yield and quality of Citrus in Kaixian.
