摘要

一项温室研究旨在确定叶面喷施磁化螯合液态铁肥对提高两种豆科植物耐旱性的影响。研究目的是确定四种处理对大豆(Glycine max)和丝绒豆(Mucuna pruriens)植物的叶面气体交换、土壤湿度和植物生长的抗旱效果。对植物的处理包括使用传统臂式喷雾器施用螯合液态铁肥(2.5% 和 5%)、在喷洒管路中安装和不安装磁铁以及使用金属卤化物灯。在进行叶面处理之前和两次水分胁迫处理之后,收集了三次气体交换测量结果。叶面喷洒和金属卤化物灯处理使九个相互关联的气体交换参数失活或失联,这些参数与植物在水胁迫条件下的防御活动相关。停用相互关联的气体交换调节功能提高了新陈代谢效率,降低了胁迫水平,并增强了植物对非生物胁迫的适应能力。此外,研究结果表明,研究处理保持或增加了植物组织和维管系统中生物结构水的水平。

Effects of Magnetized, Chelated Iron Foliage Treatments, and Metal Halide Lamps on Plant Water Structure, Water Vapor Dynamics, and Resilience for Legumes under Water Stress
A greenhouse study was conducted to determine the effects of foliar applications of magnetized, chelated liquid iron fertilizer for increasing the drought tolerance of two legumes. The study objectives were to determine the drought tolerance effects of four treatments on foliar gas exchange, soil moisture, and plant growth for soybean (Glycine max) and velvet bean (Mucuna pruriens) plants. The plant treatments included applications with chelated liquid iron fertilizer (2.5 and 5%) with a conventional boom sprayer, with and without magnets in the spray lines, and metal halide lamps. Three gas exchange measurements were collected before applying the foliage treatments and after two water stress treatments. A foliage and metal halide lamp treatment deactivated or unlinked nine interconnected gas exchange parameters that are correlated with plant defense activities during water stress conditions. The deactivation of interconnected regulatory gas exchange functions improved metabolic efficiency, reduced stress levels, and boosted plant resilience to abiotic stressors. Also, the study findings suggest that the study treatments maintained or increased the level of biologically structured water in plant tissues and vascular systems.
