| 摘要: |
| 研究以广东省梅州市梅县红肉蜜柚 Citrus maxima ""Hongroumiyou"" 种植基地的 5 a 生红肉蜜柚为试验材料，以不施肥为对照组，将有机肥和无机肥的全年单株施肥量设置为 15、20、25 kg 3种梯度，对比分析不同肥源和施肥量对红肉蜜柚外观品质和食用品质的影响。结果表明，施用肥料能显著提高红肉蜜柚的果实品质（P<0.05）；对比无机肥，施用有机肥能显著提高红肉蜜柚的可食率（P<0.05），而单果重、果形指数、含水率和出汁率并没有显著差异；随着有机肥和无机肥施肥量的增加，红肉蜜柚的单果重、可食率和出汁率均有显著的提高。考虑到无机肥对土壤和环境的危害性，红肉蜜柚栽培过程中建议用有机肥替代无机肥或有机无机肥配施。 |

| Abstract: |
| Reasonable fertilizer source and fertilizer application rate is one of the important factors to improve the fruit quality of Citrus maxima ""Hongroumiyou"". In this study, the 5-year-old C. maxima ""Hongroumiyou"" planting base in Meixian county, Meizhou city, Guangdong province was used as the experimental material. The control group was not fertilized, and the application rates of organic fertilizer and inorganic fertilizer were set to 15 kg · N-1 · Year-1, 20 kg · N-1· Year-1, and 25 kg · N-1· Year-1, respectively. The effects of different fertilizer sources and fertilizer rates on the appearance and edible quality of C. maxima ""Hongroumiyou"" were compared and analyzed. The results showed that the application of fertilizer could significantly improve the fruit quality of C. maxima ""Hongroumiyou""(P<0.05). Compared with inorganic fertilizer, the application of organic fertilizer could signifificantly improve the edible rate of C. maxima ""Hongroumiyou""(P<0.05), but there was no significant difference in single fruit weight, fruit shape index, moisture content and juice yield. With the increase of organic fertilizer and inorganic fertilizer, the single fruit weight, edible rate and juice yield of C. maxima ‘Hongrou miyou’ increased signifificantly. Considering the harmfulness of inorganic fertilizer to soil and environment, it is suggested that organic fertilizer should be used instead of inorganic fertilizer or combined application of organic and inorganic fertilizer in the cultivation of C. maxima ""Hongroumiyou"". |
