流胶病是四川柠檬产区的主要病害。该病在田间全年均有发生,以6—10月发生最多,冬春季发生极少。高温多雨季节,是流胶病为害的主要时期。果园长期积水,土壤粘重,树冠郁密可以加剧发病,所以改良环境是重要的预防措施。发生部位主要在主干,病部腐烂并流胶,影响树势,严重时造成“环割”,导致植株死亡,严重影响生产。 Silicosis is the main disease in Sichuan lemon producing areas. The disease occurred in the field throughout the year, occurring in June-October up to very little winter and spring occurred. High temperature and rainy season, is the main period of melasma damage. Long-term water orchards, soil sticky, crown Yu dense can exacerbate the disease, so the improvement of the environment is an important preventive measure. Occurred mainly in the main parts of the trunk, diseased parts of the disease and plastic flow, affecting the tree potential, resulting in serious “ring cut”, leading to plant deaths, seriously affecting the production.
