摘要
为探讨黄腐酸钾对火龙果品质及土壤不同钾素形态的影响,选取2年龄的火龙果树开展研究.结果表明,施用黄腐酸钾能显著提高果实的单果重和横径比,从而改善果型,增加其经济价值;同时,黄腐酸钾能显著提高火龙果的蛋白质、可溶性糖和可溶性固形物含量,提高果实品质;黄腐酸钾还能有效改变土壤中不同形态钾素的含量,提高土壤可交换性钾含量,有利于火龙果植株对钾素的吸收.施用黄腐酸钾对火龙果的高品质栽培具有较好的效应,在常规施肥基础上增施67.5 kg/hm^(2)黄腐酸钾效果最佳.
2-year-old pitaya trees were selected to study the effects of potassium fulvic acid on the quality of pitaya fruit and different forms of potassium in orchard soil. The results showed that fertilizer combined with potassium fulvic acid could significantly increase the single fruit weight and transverse diameter ratio of fruit, which could improve fruit shape and increase economic value;The content of protein, soluble sugar and soluble solid in pitaya were significantly increased by applying chemical fertilizer combined with potassium fulvic acid,,the quality of pitaya were improved. Potassium fulvic acid could also effectively change the content of different forms of potassium in soil, improve the content of exchangeable potassium, and promote the absorption of potassium by pitaya plants. The combination of common fertilizer and 67.5 kg/hm^(2) potassium fulvic acid had good effect on the high-quality cultivation of pitaya.
