比较了单施钾肥、单施镁肥以及钾镁肥配施分别对丁岙杨梅果实品质及营养元素的影响。结果表明,株施镁肥0.15 kg可显著提高杨梅果实单果质量、可溶性固形物、总糖、维生素C含量和株产,分别比对照提高6.48%、9.90%、7.89%、15.45和5.65%;株施钾肥1.0kg可显著提高杨梅果实单果质量、可溶性固形物、可溶性糖、糖酸比、维生素C含量和株产,分别比对照提高7.56%、11.48%、14.53%、33.38%、19.96%和22.35%,果实中钾、磷、铁含量显著提高;株施镁肥0.2kg+钾肥0.5kg可显著提高杨梅果实产量、可溶性固形物、可溶性糖、总酸、糖酸比、维生素C、硬度及株产,果实中钾、铁、钙含量显著提高。
The effects of single application of K fertilizer, single application of Mg fertilizer and application of potassium and magnesium fertilizer on fruit quality and nutritional elements of Myrica rubra were compared. The results showed that 0.15 kg of plant Mg could significantly improve fruit quality, soluble solids content, total sugar, vitamin C content and yield of M. mangium fruits by 6.48%, 9.90%, 7.89%, 15.45 and 5.65% 1.0kg potassium fertilizer could significantly improve the fruit quality, soluble solids, soluble sugar, sugar and acid ratio, vitamin C content and plant yield of the fruits of Bayberry, which increased by 7.56%, 11.48%, 14.53%, 33.38%, 19.96% and 22.35 %, The contents of potassium, phosphorus and iron in fruit increased significantly; 0.2kg potash fertilizer and 0.5kg potash fertilizer could significantly increase the fruit yield, soluble solids, soluble sugar, total acid, sugar acid ratio, vitamin C, hardness and yield , The fruit of potassium, iron, calcium content increased significantly.
