轮纹病是在梨常温贮藏烂果的主要原因。该病菌属弱寄生菌,气温达到15℃,降雨量在10mm以上,枝干上的分生孢子即散发出来,随风雨传播侵染。分生孢子随气孔侵入幼果后,不马上表现症状,而是在果实成熟及贮运期发病。莱阳茬梨常因此病难以贮藏和远销。为了控制此病,在3月中旬至9月上旬田间连续喷洒杀菌剂的基础上,研究常温下贮藏,控制茬梨轮纹病发生的技术。
Rotavirus is the main cause of rotten fruit stored in pear at room temperature. The bacteria is a weak parasitic bacteria, the temperature reached 15 ℃, rainfall above 10mm, the conidia on the branch that is emitted, spread with the wind and rain infection. Conidia with stomatal invasion of young fruit, do not immediately show symptoms, but in the ripe fruit and storage of disease. Laiyang stubble often so difficult to store and sell pear. In order to control the disease, in the middle of March to early September on the basis of continuous spraying of fungicides in the field, research at room temperature storage, control pearl ring disease occurred in the technology.
