应用~(59)Fe 研究柑桔植株根和叶片对黄腐酸铁等不同形态铁盐的吸收及其运转。结果表明:柑桔植株对~(59)Fe-铁盐的吸收利用因引入途径不同差异很大,以叶面喷施为宜,并降低铁盐溶液 pH 值有利铁盐吸收。~(59)Fe-铁盐在柑桔体内的运转与其形态有关,有机态的黄腐酸铁大于无机态的 FeSO_4,并且大部分输送到枝叶部位,尤其是新生的幼嫩组织。 Study on the Absorption and Operation of Different Forms of Ferric Iron, such as Ferric Yellow, by Roots and Leaves of Citrus Using ~ (59) Fe. The results showed that the absorption and utilization of ~ (59) Fe-Fe salt in citrus plants differed greatly due to the different ways of introduction, and the application of foliar sprays was the best. ~ (59) The Fe-Fe salt movement in citrus was related to its morphology. The ferric humate ferric oxide was larger than that of inorganic FeSO 4 in the citrus and most of it was transported to branches and leaves, especially the newborn tissue.
