铁的红色螯合物邻啡罗啉铁对苹果插根试验表明：铁肥插根处理，铁沿着靠近形成层的木质部向地上部分运输，速度可达３８．４８ｃｍ／ｈ，根系分布较少；强力高压注射铁主要沿中央木质部运输，首先充分向下运往根系，向上运输较向下运输少，运输速度可达４５０ｃｍ／ｈ。环状沟土壤浸施铁在不断根的情况下很难被根吸收，断根吸收、运输铁的机制与插根相同。
The results showed that the iron fertilizer was inserted into roots and the iron was transported to the aerial part along the xylem near the formation layer at the speed of 38.48cm / h with less root distribution ; High-strength injection iron mainly along the central xylem transport, first fully down to the root, upward transport less than the lower transport, transport speed up to 450cm / h. The annular ditch soaked in iron in the case of continuous root is difficult to be absorbed by the root, root and root absorption, the mechanism of transport of iron and the same rooting.
