| 摘要: |
| 在对广西田阳、田东、钦州和防城果主要产区的代表性果园(16个)进行土壤农化性状调查的基础上,进行N、P、K、Mg田间施肥试验,试验小区5个,随机区组排列,每小区5株,重复4次。土壤调查表明,供试果园土壤有机质含量(g/kg)11.44~12.09,全N量(g/kg)0.53~0.92,全P量(g/kg)0.20~0.38,全K量(g/kg)5.14~18.43。速效P(mg/kg)0.8~26.2,速效K(mg/kg)33.9~53.3。田间试验结果表明,施N、K配镁肥,能改善果植株的营养状况。施钾配镁肥,落果率可减少20.87%。在试验施肥条件下,单株产量提高0.85千克/株。增施N、K配施Mg肥,单果重达323g,此外施K,可提高果实粗蛋白和VC含量,可食部分略有增加。N2PK2Mg处理的果在室内气温26.5℃~32.5℃,64%~89%的相对湿度下,可贮藏23d。 |

| Abstract: |
| Field experiment was carried out for the fertilization techniques of mango based on the investigation of soil nutrient conditions of mango orchard.The poor soil nutrient condition was one of the main reasons for being low yield of mango in Guangxi. Increased application of N.P.K and Mg could promrote the growth of mango trees,raise mango yield,improve its quality and lengthen its preservation time. Application of K and Mg reduced the fruit dropping of mango by 21%. The crude protein and VC content and edible proportion of fruits were lightly increased by applying potash fertilizer. |
