七十年代以来,水稻细菌性褐条病已在我省局部地区严重发生。病菌以伤口侵入为主。病株残体、病田土壤和病株种子均可带菌越冬而成为初侵染来源。淹水、高湿和偏低的温度有利于病害的发生。同一品种不同生育期之间的抗病性不同,苗期和孕穗末期易于感病。28个品种抗病性测定的结果显示,品种间抗病性差异显著。本文还提出了有关病害防治的具体建议。
Since the seventies, rice bacterial brown streak has been serious in some areas of our province. Pathogenic bacteria invade the wound. Diseases of diseased plants, disease soil and diseased plants can be infected with winter and become a source of early infection. Flooding, high humidity and low temperatures are conducive to the occurrence of diseases. The same variety of different growth stages of disease resistance between different seedling and booting end of susceptible susceptible. The results of disease resistance of 28 cultivars showed that there was significant difference in disease resistance among cultivars. This article also put forward specific suggestions on disease prevention and control.
