| 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。

| Abstract: | Contents of N,P,K,Ca,Mg,S,Zn,B,Fe in organs of 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,respectively,indicating dragon fruit was high-potassium plant.Application of K should be stressed since fruit removes a considerable amount of K. |
