1960—62年初步調查发現:桃树腐烂病疤主要分布在主干与主枝上,其中主枝基部(五(木义)骨)占60％;病疤多为西南向;流胶为发病后的共同表現;病害可深入皮层与木质部。各主要栽培品种均能感病,以大久保等最重,士蒼与耐寒品种病輕。病菌可自剪口、冻伤、虫伤等处侵入。3—10月田間接种均能发病,潛育期4—10天,以春季較短。病害每年自3月开始发生,3—5月最为严重,以后随树势生长旺盛,病害发展卽受限制。冻害为主要誘因,凡栽培不当如肥、水过多和过晚,以及与秋菜間作等促使徒长或延期休眠而誘发冻害者,均能誘致腐烂病,改进以上栽培管理,提高抗冻、抗病力是防治腐烂病的根本途径。
1960-62 preliminary survey found: peach rot disease scar mainly in the trunk and the main branch, including the main branch of the base (Wu (木 meaning) bone) accounted for 60%; scar mostly southwest; flow of plastic for the disease After the common performance; disease can be deep cortex and xylem. The major cultivars are susceptible to the heaviest such as Okubo, Shi Cang and cold-tolerant varieties of disease light. Germs can be cut from the mouth, frostbite, insect pests and other places invaded. 3-October field vaccination can attack, the incubation period of 4-10 days to spring is shorter. Diseases begin each year from March to March, the most serious in March-May. Afterwards, the disease grows vigorously and the disease development is limited. Frost damage as the main incentive, where improper cultivation such as fertilizer, water too much and too late, and between autumn and vegetables and other appetite or prolonged dormancy and induce frost damage, can induce rot disease, improve the above cultivation and management, improve frost resistance, Disease resistance is the fundamental way to prevent rot disease.
