为探究中微量元素对赣南脐橙产量及品质的影响,优化脐橙中微量元素肥料施用方案,开展了纽荷尔脐橙追施4种不同中微量元素肥料的田间试验。结果表明:追施中微量元素肥料可提高脐橙的挂果数、单果质量、果实横径,其中习惯追肥+追施中微量元素肥料(T2)处理的挂果数比习惯追肥(CK)处理的提高8.1%~22.9%;追施中微量元素肥料可改善果实品质,其中T2处理的脐橙可溶性固形物、可溶性糖、维生素C含量比CK处理的分别提高4.4%~9.0%、0.8%~10.2%、3.3%~8.1%,总酸含量降低2.6%~15.2%,糖酸比、固酸比、可食率分别提高5.7%~25.6%、9.0%~24.3%、1.7%~11.3%。追施中微量元素肥料可提高纽荷尔脐橙产量及品质,以习惯追肥基础上追施中微量元素肥料的效果最优。
To investigate the effect of medium and trace elements on the yield and quality of Gannan navel orange and to optimize the application scheme of medium and trace element fertilizer for navel orange, a field trial of four different medium and trace element fertilizers is conducted for Newhall navel orange. The results show that topdressing medium and trace element fertilizer can improve the number of hanging fruits, single fruit weight and fruit transverse diameter of navel orange, among which the number of hunging fruits in the treatment of habitual topdressing+topdressing medium and trace element fertilizer(T2) is 8.1%-22.9% higher than that in the treatment of habitual topdressing(CK). Topdressing medium and trace element fertilizer can improve the fruit quality, among which the soluble solid, soluble sugar and vitamin C content of navel orange in the treatment of T2 increase from 4.4% to 9.0%, 0.8% to 10.2% and 3.3% to 8.1%, respectively, and the total acid content decreased from 2.6% to 15.2%, while the sugar-acid ratio, solid-acid ratio and edible rate increase from 5.7% to 25.6%, 9.0% to 24.3% and 1.7% to 11.3%, respectively, compared with those in CK treatment. Topdressing with medium and trace element fertilizer can improve the yield and quality of Newhall navel orange, and the best results are obtained by topdressing with medium and trace element fertilizer on the basis of habitual topdressing.
