摘要: 通过研究连续3年施用土壤调理剂硅钙钾镁肥对蜜柚产量、品质和土壤性状的影响,了解硅钙钾镁肥的合理用量,为科学施用提供理论依据。结果表明,施用硅钙钾镁肥3年,虽然受蜜柚树体本身差异以及大小年(2015年为高产年)的影响, 各年度大部分处理的蜜柚产量均有不同程度的提高, 对蜜柚个数和裂果率影响不大。施入不同用量的硅钙钾镁肥能不同程度提高蜜柚Vc含量、 可溶性糖含量, 总酸含量变化不明显, 酸度平均值呈现下降趋势, 糖酸比差异并不显著。3年施用硅钙钾镁肥能提高土壤pH值、有效磷、 速效钾、 交换性钙和交换性镁含量, 增强土壤抗酸化能力。考虑到成本因素,硅钙钾镁肥以750 kg/hm2的用量对蜜柚增产效果及品质最好。

Abstract: The authors studied the effects of 3- year continuous application of silicon calcium potassium magnesium fertilizer on yield, quality of honey pomelo and soil properties, to understand the reasonable application amount of silicon calcium potassium magnesium fertilizer. The results showed that, with the application of silicon calcium potassium magnesium fertilizer for 3 years, although affected by tree itself and the major and minor year (high yield in 2015), honey pomelo yield was improved at different degrees each year, and the fertilizer had little effect on honey pomelo number and fruit cracking rate. Application of silicon calcium magnesium potassium fertilizer could increase the Vc content and soluble sugar content of honey pomelo to different extents. The total acid content of honey pomelo did not change significantly, but the average total acid decreased. The sugar/acid ratio of honey pomelo did not differ significantly between the treatments and the control. The application of silicon calcium magnesium potassium fertilizer could improve soil pH value, available phosphorus, available potassium, exchangeable calcium and magnesium content, enhance soil antioxidant ability. In conclusion, considering the cost, the yield and quality of honey pomelo were the best when the application amount of silicon calcium potassium magnesium fertilizer was 750 kg/hm2 .
