| 摘 要： | 以两种铁源和供铁方式以及增加锌元素等,对缺铁黄叶的柚砧尤力克柠檬(Citrus Limon)进行复绿矫治研究。结果表明,尿素铁+硫酸锌,硫酸亚铁+硫酸锌进行叶面喷施和尿素铁+硫酸锌,硫酸亚铁+柠檬酸进行埋瓶浸根,叶片复绿效果较好,并有助于提高果实产量和品质。试验还对复绿的机理和供铁、锌元素对其他矿质元素的影响进行了探讨。

| Abstract: | A field trial was conducted to investigate the strategy for the correction of Fe deficiency-induced chlorosis in Eureka lemon (Citrus limon) grafted onto pummelo (C. grandis) rootstock. Foliar spray of the trees with urea-Fe plus zinc sulphate or with ferrous sulphite plus zinc sulphate, and root feeding with urea-Fe plus zinc sulphate or ferrous sulphite plus citric acid by means of flasks containing the nutrient solution buried in. the soil gave marked results. The trees regreened soon and the output and quality of the fruit proved better than the control. The mechanism of leaf regreening and the influence of Fe and Zn application on other minerals in the plants are discussed. |
