拓展好文：芦荟常见的病害和预防措施 芦荟常见病害及预防措施芦荟常见病害主要有炭疽病、褐斑病、叶枯病、蚕病和细菌病等。家庭盆栽芦荟应以防病为主，在病害发生前，选择抗病品种和优质无病苗，其观赏价值有所下降。防治：发病前，或除去病株病部后，向芦荟中施0.5-0.8石灰当量的波尔多液（即每100公斤水加硫酸铜和石灰各0.5-0.8公斤）。叶面能有效防止和抑制病菌的侵袭和传播。***治疗。发病后直接施用全身转导治疗剂如托布津、芦毒素等，以及抗生素如硫酸链霉素、农用链霉素、春雷霉素、井冈霉素等，可杀灭芦荟中的病原菌。控制***传播的病原体。友情提醒：芦荟是生长在恶劣的沙漠环境中的“沙漠百合”。生命力强，不需要准备特殊的土壤；除不适合芦荟健康生长的粘土和硬化土外，任何土壤均可使用。适应。
