摘要
测定了火龙果植株各器官的氮、磷、钾、钙、镁、硫、锌、硼、铁的含量。结果表明,花蕾的含氮量最高,茎的磷、钙、镁、硫、锌含量最高,果皮的钾、硼含量最高,根系的铁含量最高;果实中氮∶磷∶钾=4.86∶1.00∶10.12,茎中氮∶磷∶钾=1.46∶1.00∶1.81,说明火龙果是高钾植物。认为火龙果果实带走的钾素最多,故应特别重视钾肥的使用。
Contents of N, P, K, Ca, Mg, S, Zn, B, Fe in organs ot dragon fruit plant were measured. Results showed that the highest N content was in flower bud, the highest P, Ca＇, Mg, S, Zn were in stem, the highest K and B were in peel, and the highest Fe was in root. The contents of N ： P ： K were 4.86 ： 1.00 ： 10.12 in fruit, and 1.46 ： 1.00 ： 1.81 in stem, respeetively, indicating dragon fruit was high-potassium plant. Application of K should be stressed since fruit removes a considerable amount of K.
