摘　　要：甘蔗宿根黄化病是近10余年发现的一种无病原菌感染的生理性病害,对甘蔗产量和品质有严重影响,逐渐成为影响广西蔗糖产业发展的重要因素,且有逐年加重趋势。目前全世界范围内仅见广西发生宿根甘蔗生理性黄化病,对其病因存在多种解释,但尚未明确,也未找到高效的复绿措施解决生产上日益严重的黄化病情。本研究开展了广西宿根甘蔗生理性黄化病现状调查,对发病点的地理位置、土壤性质、连作和轮作情况及病因进行分析和讨论,以期为早日实现甘蔗宿根黄化病有效防控提供依据。The chlorosis disease of ratoon sugarcane is a physiological disease without pathogen infection has been known for more than a decade and only be reported occurring in Guangxi by now.It has a serious effect on the yield and quality of sugarcane and was becoming an important factor affecting the development of sugarcane industry in Guangxi.At present,there are many explanations for its etiology,but the etiology has not been determined and no efficient measures have been found to solve the increasingly serious chlorosis in fields planting.In order to provide the basis for the early realization of the effective prevention and control of the chlorosis disease of ratoon sugarcane,an investigation was carried out on the status of the geographical location,soil property,continuous cropping and crop rotation,prevention and control measures of the investigate sites,and the etiology were analyzed and discussed.
