樱花在生长过程中常常会出现枝干流胶现象,其具体原因有如下几种。生理性流胶:当植株受到霜冻、冰雹危害以及机械外伤或肥水管理不当引起的树势过弱等引起的流胶。病理性流胶:是一种子囊菌危害,属真菌性病害,子囊病原菌在枝条或已死的枝条或枝干上越冬,当条件适宜时就会产生孢子,孢子发芽适温28℃～32℃。分生孢子靠雨滴在植株之 Sakura often appear in the growing process of plastic flow branches, the specific reasons are as follows. Physiological hydrogel: When the plants are exposed to frost, hail and mechanical injury caused by improper management of fertilizers caused by too weak shrubs and other plastic flow. Pathological plastic flow: is an ascomycota hazard, is a fungal disease, ascosporogenous pathogen in the branches or dead branches or branches overwintering, when appropriate conditions will produce spores, spores germination suitable temperature 28 ℃ ~ 32 ℃ . Conidia rely on raindrops in the plant
