【常见
#病害防治 篇】 1、高锰酸钾防治#白粉病 。 用浓度为0.02~0.03%的高锰酸钾溶液喷花,几天后病斑会逐渐消失,病叶恢复正常生长。 2、食醋防治白粉病。 将食醋加水配制成5%的溶液喷雾,2—3次后可防治白粉病。 3、小苏打防治白粉病。 小苏打溶液为弱酸性,病原菌在弱酸性环境下难以生存,因此,用0.2%小苏打溶液对花卉喷雾,防治白粉病效果好。 4、大蒜汁防治腐烂病。 用刀将花卉的腐烂部位刮掉,露出病部周围的健康组织,然后,均匀将大蒜汁涂抹在伤口处,每次间隔一周,2~3次即可治愈。 5、用碘酒防治腐烂病。 将花卉腐烂部分全部刮除,涂抹碘酒,7~10天后再涂抹一次,直至彻底治愈。 6、草木灰防治根腐病。 将花盆表层土壤去除露出根部,用适量草木灰(视花盆大小而定)覆盖根部上面,再用泥土覆盖在草木灰上,防治根腐病效果很好,尤其是水仙、仙人掌类。
