番茄是吉林省长白县蔬菜主栽品种之一,常年栽培,面积较多。近年来,番茄生理性病害的发生呈逐年上升趋势,发生比例(面积)占病害总量的60%以上,给菜农造成了较大损失。由于对生理性病害认识不够,菜农经常误认作其为传染性病害而用药剂防治,不仅没有效果,还往往延误了防治时机,造成更大损失。由于生理性病害和传染性病害的发病原因、发生特点和防治方法有所不同,所以必须在正确识别前提下采取对应的防治措施进行解决。下面介绍几种在当地较常发生生理性病害的识别与防治。
Tomato is one of the main cultivars of vegetables in Changbai County of Jilin Province, perennial cultivation, more area. In recent years, the incidence of physiological diseases of tomato showed an upward trend year by year, with the proportion (area) accounting for more than 60% of the total amount of the diseases, which caused great losses to vegetable farmers. Because of lack of understanding of physiological diseases, vegetable farmers often mistake them for infectious disease prevention and treatment with agents, not only ineffective, but also often delay the timing of prevention and control, resulting in greater losses. Due to physiological diseases and infectious diseases, the causes of occurrence, occurrence characteristics and methods of prevention and treatment are different, so we must take appropriate prevention and control measures to solve the problem under the correct identification. Here are some of the more common in the local occurrence of physiological disease identification and prevention.
