    摘要:

    针对我国柑橘园土壤交换性镁及微量元素普遍缺乏导致产量品质下降的问题，利用创制的含微量元素镁肥，以江西赣州脐橙为试验材料，采取田间小区试验，比较含微量元素镁肥（MG1）、含微量元素钙镁肥（MG2）、速溶镁肥土壤施用（MG3S）、速溶镁肥叶面喷施（MG3F）对赣南脐橙产量、品质、养分含量的影响。结果显示，施用4种镁肥均可显著提高果实产量，其中MG1和MG2分别增产28.82%和24.76%，MG3S和MG3F分别增产18.78%和16.01%；施用镁肥可显著增加脐橙单果质量、可溶性固形物和维生素C含量、固酸比，改善果实品质，其中以MG2综合评分得分最高，即果实品质最佳；含微量元素镁肥明显提高果实养分积累，MG1和MG2的钙携出量分别显著提高32.12%和53.50%，镁携出量分别显著提高25.28%和29.90%，果实氮、硼、锌、钼养分积累量也显著增加。结果表明，施用镁肥对赣南脐橙有显著的增产提质效果，含微量元素镁肥、钙镁肥能明显改善树体钙、镁及硼、锌、钼营养状况，增产提质效果最好；速溶镁肥土壤施用和叶面喷施效果相近。

    Abstract:

    Gannan navel orange was used to study the effects of self-developed magnesium fertilizer containing trace-elements （MG1）， calcium-magnesium fertilizer containing trace-elements （MG2）， instant magnesium fertilizer in soil spraying （MG3S）and foliar spraying （MG3F）on quality and nutrients of fruit to solve the declines in yield and quality of fruit in Gannan navel orange caused by exchangeable magnesium and trace-elements in the soil of citrus orchards in China. The results showed that the application of four types of magnesium fertilizers significantly increased the yield of fruit， with an increase of 28.82% and 24.76% in MG1 and MG2， and 18.78% and 16.01% in MG3S and MG3F， respectively. The application of magnesium fertilizer significantly increased the quality of single fruit， the content of soluble solids and vitamin C， the ratio of solids to acid， and improved the quality of fruit. Among them， the comprehensive score in MG2 was the highest， indicating the quality of fruit is the best. Magnesium fertilizer containing trace-elements significantly increased the accumulation of nutrients in fruits. The calcium carrying capacity and the magnesium carrying capacity of MG1 and MG2 increased by 32.12% and 53.50%， 25.28% and 29.90%， respectively. The accumulation of nutrients including nitrogen， boron， zinc， and molybdenum in fruits increased significantly as well. It is indicated that the application of magnesium fertilizer has a significant effect on increasing the yield and improving the quality of Gannan navel oranges. Magnesium fertilizer and calcium magnesium fertilizer containing trace-elements can significantly improve the content of nutrients including calcium， magnesium， boron， zinc， and molybdenum in the tree， with the best effect on increasing the yield and improving the quality. The application of instant magnesium fertilizer in soil spraying and foliar spraying have similar effects.
