近几年,随着果树面积的扩大,表现果树花叶病的植株也越来越多,特别是一些成龄树。在生产上,许多果农误以为是缺铁造成的黄叶病,猛喷硫酸亚铁,不仅无效,还会造成一定的经济损失。其实,果树花叶病与黄叶病是有根本区别的,是截然不同的两种病害。 In recent years, with the expansion of fruit trees, there are more and more plants displaying fruit mosaic diseases, especially some adult trees. In the field of production, many fruit farmers mistakenly think that they are yellow leaf diseases caused by iron deficiency and fierce spraying of ferrous sulfate, which is not only ineffective but also causes some economic losses. In fact, fruit mosaic disease and yellow leaf disease are fundamentally different, is completely different from the two diseases.
