| 摘 要： | 为探讨香蕉体内氮磷钾的含量及分布特点,采用整株肢解法,研究了香蕉不同生育期根、球茎、假茎、叶及果、果轴的氮、磷和钾含量.结果表明,不同生育时期,香蕉根系、假茎、球茎、叶、果实和果轴6个器官中的氮磷钾含量与分布不同.在香蕉抽蕾前,氮分布为叶＞球茎＞假茎＞根系,磷为假茎＞叶＞球茎＞根系,钾为假茎＞根系＞叶＞球茎;抽蕾后,氮...

| Abstract: | To research into the distribution characteristic of N,P and K contents in banana,banana trees were uprooted and divided into 6 parts in the growth phase and N,P and K contents of different parts were measured.Results showed that nitrogen,phosphorus and potassium contents of root,corm,pseudostem,leaves,fruit and columella were different in the growth phase.Before shooting of banana,nitrogen content was in rank of leaf > corm > pseudostem > root,phosphorus content in rank of pseudostem > leaf > corm > root,po... |
