果树资源学报2023,4(4):32-34不同浓度镁肥处理对蜜柚果实粒化的影响罗遵喜,莫永坤,王治富,何芬(荔波县农业农村局,贵州荔波558400)收稿日期:2023-05-05第一作者简介:罗遵喜(1982-),男,高级农艺师,主要从事作物遗传育种研究。E-mail:luozunxi@163.com摘要:【目的】为了解镁肥对蜜柚果实粒化的影响,在蜜柚果园常规施肥的基础上,通过增施不同浓度的镁肥,以期获得蜜柚果实粒化率最低时的镁肥施用浓度。【方法】针对蜜柚粒化率较高的果园,于2018、2019年连续2年在蜜柚始花期增施不同浓度镁肥,在蜜柚成熟期调查其单果质量、果皮质量、果皮厚度、可溶性固形物质量分数、粒化率等。【结果】与对照相比,株施0.6kg镁肥处理后,蜜柚果实粒化率从40.18%下降到15.27%,果皮厚度从20.17mm下降至13.55mm,可溶性固形物质量分数从10.1%提高至10.9%。【结论】增施镁肥可显著降低蜜柚果实粒化率,使得其果皮变薄,糖度增加,品质提高。关键词:蜜柚;镁肥;果实粒化文章编号:2096-8108(2023)04-0032-03中图分类号:S666.3文献标识码:AEffectsofDifferentConcentrationsofMagnesiumFertilizeronGranulationofHoneyPomeloFruitLUOZunxi,MOYongkun,WANGZhifu,HEFen(AgricultureBureauOfLiboCountryinGuizhouProvince,LiboGuizhou558400,China)Abstract:【Objective】Inordertounderstandtheeffectofmagnesiumfertilizeronthegranulationofhoneypomelofruit,onthebasisofconventionalfertilizationinthehoneypomeloorchard,theapplicationconcentrationofmagnesiumfertilizeratthelowestgranulationrateofhoneypomelofruitwasobtainedbyaddingdifferentconcentrationsofmagnesiumfertilizer.【Meth-ods】Fororchardswithhighgranulationrateofhoneypomelo,differentconcentrationsofmagnesiumfertilizerwereaddedattheinitialfloweringstageofhoneypomelofor2consecutiveyears.【Results】Increasingmagnesiumfertilizercouldsignificantlyreducethegranulationrateofpomelofruit,makeitspeelthinner,sugarcontentincreased,andqualityimproved.【Conclusion】Comparedwiththecontrol,thegranulationrateofpomelofruitdecreasedfrom40.18%to15.27%,thepeelthicknessde-creasedfrom20.17mmto13.55mm,andthesolublesolidsincreasedfrom10.1to10.9inthetreatmentof0.6kgmagnesi-umfertilizerperplant.Keywords:Honeypomelo;magnesiumfertilizer;lignification荔波蜜柚是荔波县主导的精品...
