以“台农1号”芒果为试材，田间试验研究了花前土施不同用量硝酸钙对芒果果实钾、钙、镁含量及产量、品质的影响。结果表明：(1)与不施钙相比，土施钙肥可明显提高果实糖酸比，其原因主要是降低了可滴定酸含量，提高了可溶性糖含量，同时可显著提高果实Vc含量，降低贮藏期果实发病率，在土施钙150 g/株时产量最高，增产率为14．25%。(2)在一定钙用量范围内，土施钙肥可显著提高果肉钙含量，使果皮、果肉与果核的钾、镁含量下降。(3)果皮、果肉及果核钙含量与钙肥用量呈正相关，钾、镁含量与钙肥用量呈负相关。(4)果实可溶性糖含量、 Vc含量及糖酸比与钙肥用量呈正相关，果实可溶性固形物含量、可滴定酸含量、失重率、发病率与钙肥用量呈负相关。土壤增施钙肥有利于提高芒果果实品质，提高果实耐贮性。

A field trial was undertaken to evaluate the effects of applying Ca( NO3 ) 2 in soil before flower period on the contents of potassium, calcium, magnesium and quality of “tainung No. 1” mango. The results showed that: (1) Compare with the results of the control, applying calcium fertilizer could obviously increase the fruit sugar acid ratio because of the increase of content of soluble sugars and acidity reduced, and improve the vitamin C in the fruit, reduce the rotten fruit rate during stor-age. The highest yield occurred when 150 g/plant calcium was applicated, and the yield increased by 14. 25% compared to the control. (2) By applying calcium fertilizer, the calcium content of pulp in fruit was significantly increased, the magnesi-um and potassium contents of peel, pulp and seed in fruit reduced. (3) The calcium contents of peel, pulp and seed in fruit had positive correlation with the calcium application amounts, and the potassium and magnesium contents of peel, pulp and seed in fruit had negative correlation with the calcium application amounts. (4) The contents of soluble sugars, vitamin C and sugar acid ratio were positive correlation with the calcium application amounts. The contents of soluble solid, acidity, weight loss ratio and the rotten fruit rate were negative correlation with the calcium application amounts. It suggested that applying Ca( NO3 ) 2 in soil could increase quality and improve storability of mango during storage.
