本文从果实病原来源、侵入期、果实不同发育阶段的生理生化变化,以及防治技术等方面进行了研究。证明果实病害的主要病原来源于病技干,还来源于苹果、杨树的其他病害。落花后的幼果即具有很高的受侵力,直至采收前皆可在高湿条件下陆续受侵染。幼果受侵的特点,直至采收前后表现病态。病菌所以存在潜伏发病的现象,初步认为是受果实不同发育阶段,酚、糖量规律性变化的制约。在防治上采取技干病原铲除,花后极早喷药保护果面的办法,收效良好。
This article from the source of fruit pathogens, invasion period, the physiological and biochemical changes in different developmental stages of fruit, as well as prevention and treatment technology and other aspects were studied. Prove that the main pathogen of fruit disease stems from disease and stem, but also from apple, poplar and other diseases. Young fruit after the flower that is highly invasive, until the harvest can be one after another in the high humidity conditions by infection. The characteristics of young fruit invasion, until the performance before and after harvest pathological. Pathogenic bacteria so there is a latent incidence of the disease, initially believed to be different stages of development of fruit, phenol, sugar changes in the rules of the constraints. In the prevention and control to take the eradication of the pathogen, flower protection after spraying very early fruit approach, with good results.
