    摘要:

    田间试验研究了常规施肥基础上花前增施镁肥对芒果果实产量、品质及经济效益的影响。试验设3个处理,空白对照、常规施肥和增施Mg肥。结果表明:与常规施肥相比,增施Mg肥处理芒果单株产量可达24.12 kg/株,折合产量12.06 t/hm2,增产9.7%;果实营养品质得到提升,可溶性固形物含量提高9.6%,可滴定酸降低14.6%,固酸比提高28.1%;净收入较常规施肥处理高5 429元/hm2,提高21.2%。土壤增施镁肥是提升芒果产量与品质的有效措施。

    Abstract:

    A field experiment was carried out in Hainan to investigate the effects of applying MgSO4 in soil before flower period on the yield of mango and its quality,and the benefits and cost analysis was estimated thereafter.The experiment had three treatments:no fertilizer(CK),farmers practice(FP)and applying magnesium fertilizer(Mg).The result showed that the yield was higher in the applying magnesium fertilizer treatment(12.06 t/hm2),which increased by 9.7% than that of traditional fertilizers treatment.As compared with FP treatment,applying magnesium fertilizer increased the fruit total soluble solid and tssacid ratio by 9.6% and 28.1%,and reduced total titration acid by 14.6%,respectively.The net benefit of fruit production was the higher in the applying magnesium fertilizer treatment due to higher yield.In summary,mango applied with magnesium was economical viable which offers a new perspective for mango nutrients management.
