| The contents of K, Ca, Mg, B, Fe, Cu, Mn, Zn were determined in 5 kinds of carnation organ by ICP-AES with wet digestion to study the distribution of nutrition. The results indicated that the content of K increased gradually. The content of Ca increased rapidly in early stage, it has a drastic reduction and in bud swelling period, but increased slightly in the cross period. The content of Mg increased quickly in early stage, but reduced gradually before its blossom.The content of B increased gradually in early stage, and increased dramatically in the cross period, which reached 4.4 times of the level of leaves. The content of Fe, Cu, Mn, Zn increased
gradually as the flower bud format, it began to decrease in the cross period. the content of Mn reduced more rapidly. |
