钙、镁、硼、锌、铁是脐橙必需的中微量元素,施用量不足或过量,均会影响脐橙的生长发育、产量及品质。综述了施用钙、镁、硼、锌、铁等5种中微量元素与脐橙品质之间的关系。考虑脐橙园土壤中微量元素的基础含量及果树树龄,推荐施用与氮、钾等量的氧化钙及与磷等量的氧化镁;推荐基施硫酸锌约40 g/株,喷施锌肥质量分数控制在0.2%~0.3%;硼砂以15 g/株为宜,喷施硼肥质量分数控制在0.3%左右;基施螯合铁铁肥约60 g/株,或以树干输液的方式每株施用质量分数约0.36%的乙二胺四乙酸(EDTA)螯合铁铁肥500 mL。
Calcium, magnesium, boron, zinc and iron are essential medium and trace elements for navel oranges, either of which insufficient or excessive application will affect the growth, yield and quality of navel oranges. The relationship between the application of 5 medium and trace elements, calcium, magnesium, boron, zinc and iron, and the quality of navel orange is reviewed. Considering the basic content of trace elements in the soil of the navel orange orchard and the age of the fruit trees, it is recommended to apply calcium oxide equivalent to nitrogen and potassium and magnesium oxide equivalent to phosphorus. It is recommended to apply basal fertilizer zinc sulfate about 40 g/plant and it is appropriate to control the spraying mass fraction of zinc fertilizer at 0.2%-0.3%. Borax should be 15 g/plant and the mass fraction of spraying boron fertilizer is controlled around 0.3%. It is better that the basal application of chelated iron fertilizer is about 60 g/plant, or to apply 500 mL/plant of 0.36% mass fraction EDTA chelated iron fertilizer in the form of trunk infusion.
