摘要
在美国,一种相对较新的铁肥是FeHBED [Fe-N,N ' -双(2-羟基苯基)乙二胺-N,N ' -双乙酸酯],它是一种螯合物,对铁的稳定常数大于FeEDDHA [fe -乙二胺-N,N ' -双(o-羟基苯基乙酸酯)]。本研究比较了大豆[甘氨酸max (L.)]稳定。]在两个温室种植期间,对FeHBED、FeEDDHA-1(~ 80%的邻位异构体)、FeEDDHA-2(~ 50%的邻位异构体)和FeEDDHSA [fe -乙二胺- n, n -二([2-羟基5-巯基])乙酸]进行了研究。FeHBED和FeEDDHA-1对所有测量参数(叶绿素水平、干物质产量、铁吸收)均有正响应,差异不显著(p < 0.05)。0.05水平)。这两种产品的性能相似。FeEDDHA-2和FeEDDHSA的反应一般小于FeHBED或FeEDDHA-1。通过一项简单的实验室试验预测了四种材料增加干物质或铁吸收的相对有效性,该试验测量了施用铁与土壤孵育1周后仍可溶解的比例。
Laboratory and greenhouse evaluation of four iron fertilizer sources
A relatively new iron fertilizer in the United States is FeHBED [Fe-N,N′-bis(2-hydroxybenzyl)ethylenediamine-N,N′-diacetate], a chelate with a stability constant for ferric iron greater than FeEDDHA [Fe-ethylenediamine-N,N′-bis(o-hydroxyphenylacetate]. This study compared response of soybean [Glycine max (L.) Merr.] over two greenhouse cropping periods to FeHBED, FeEDDHA-1 (∼80% ortho-ortho isomer), FeEDDHA-2 (∼50% ortho-ortho isomer), and FeEDDHSA [Fe-ethylenediamine-N,N-di([2-hydroxy 5-sulfophenyl])acetate]. FeHBED and FeEDDHA-1 gave positive responses to all measured parameters (chlorophyll level, dry matter production, Fe uptake) that were not significantly different (.05 level) from each other for the two cropping periods. The two products were similar in performance. FeEDDHA-2 and FeEDDHSA generally gave lesser responses than FeHBED or FeEDDHA-1. The relative effectiveness of the four materials to increase dry matter or Fe uptake was predicted by a simple laboratory test, which measures the proportion of applied Fe remaining soluble after a 1-wk incubation with soil.
