摘　　要：为探究施用牡蛎壳土壤调理剂对土壤及黄地脐橙果实品质的影响,进行连续两年的田间实验。实验设置为对照组(2019年)(0 kg/棵)、实验组第一年(2020年)(5 kg/棵)和实验组第二年(2021年)(10 kg/棵)。测定土壤pH值、有机质和交换性钙含量,以及黄地脐橙果实产量与品质,探究牡蛎壳土壤调理剂对土壤和果实品质的改良效果。结果显示,与2019年相比,2020年、2021年施用牡蛎壳土壤调理剂后,土壤pH值分别提高了2.47和2.14,土壤有机质含量分别提升了55.19%和67.68%,土壤交换性钙质量摩尔浓度分别增加了2.00,6.61 cmol/kg;实验地的黄地脐橙产量逐年递升,2020年产量较2019年增加50.0%,2021年产量较2020年增加144.4%;在果实糖酸比方面,施用牡蛎壳土壤调理剂后,2020年、2021年较2019年分别增加6.37%和25.26%;维生素C质量比也逐年增长,与对照组(2019年)的0.41 mg/g相比,第一年(2020年)施用牡蛎壳土壤调理剂后维生素C质量比提高至0.53 mg/g,第二年(2021年)施用牡蛎壳土壤调理剂后,维生素C质量比提高至0.68 mg/g。说明,施用牡蛎壳土壤调理剂可明显改善黄地脐橙土壤酸化情况,提高土壤有机质和交换性钙含量,同时可有效提升果实的产量及品质。In order to explore the effects of oyster shell soil conditioner on soil and fruit quality improvement of Huangdi navel orange,a two consecutive years′field tests was carried out during 2020-2021.The total amount of soil conditioner applied to different oyster shells was set as control(0 kg/tree)and test group(5 kg/tree)in first year,and 10 kg/tree in second year,respectively.Several indices,such as soil pH value,organic matter and exchangeable calcium content,the yield and quality of Huangdi navel orange fruit were measured to evaluate the effects of fertilization.The results showed that compared with 2019,the soil pH value increased by 2.47 and 2.14,respectively after applying oyster shell soil conditioner in 2020 and 2021;The content of soil organic matter increased by 55.19%and 67.68%,respectively;The exchangeable calcium content in soil increased by 2.00,6.61 cmol/kg,respectively.Noticeably,the output of Huangdi orange in 2020 and 2021 increased by 50.0%and 144.4%from the previous year,respectively.Increment of 6.37%and 25.26%in fruit sugar acid ratio was observed after the first and second year fertilization.Compared with 0.41 mg/g of the control group(2019),the content of vitamin C increased to 0.53 mg/g after the first year of application,and to 0.68 mg/g after the second year.The present results showed that the application of oyster shell soil conditioner could significantly neutralize soil acidification,increase the content of soil organic matter and exchangeable calcium,and effectively improve the fruit yield and quality of Huangdi navel orange.
