I have engaged in the research of rice stripe blight control for many years in Shanghai farm and found some problems: though there were some reports of research on rice stripe blight resistance, strategy of prevention and cure for the disease has been face to farmer mainly, while geographical location, cultivars and cultivation system adopted on the Farm all affect the effect of control. On the other hand, our Farm has paid attention to the chemical prevention and cure for rice stripe blight and ignored other measures. As for the chemical prevention and cure, phenomenon of drug-resistance and bad effect of prevention and cure existed usually.

本人在上海农场多年从事该课题研究过程中发现的问题：目前对水稻条纹叶枯病研究的报道较多，在防治对策上主要是针对农户，缺乏关于农场地域因素、品种、栽培制度等因素对水稻条纹叶枯病发生及防治的影响的报道；在水稻条纹叶枯病的防治上，农场仍是以化学防治为主，对其他防治措施还不够重视；在化学防治过程中，存在抗药性、防效不佳等问题。

Generation amount of rice hopper in different cultivation and its relations with rice striper,natural living pattern in field on different varieties had been observed.

文章通过研究不同栽培方式下灰飞虱发生数量及其与水稻条纹叶枯病的发生关系、不同水稻品种间条纹叶枯病田间自然消长规律。

The results showed: Difference of rice striper on different varieties was significant,positive correlation was between amount of hopper and rice striper generation.Late sowing and simple cutivation would be helpfull for reducing rice striper in early period.

结果表明：不同水稻品种间条纹叶枯病发病程度差异明显；而灰飞虱发生数量与条纹叶枯病的发生程度呈正相关；而推迟播期、推广轻简栽培方式有利减轻前期水稻条纹叶枯病的病情。

The physiological and biochemical resistant mechanism of tea cultivars to tea brown blight caused by Guignardia camelliae. Making use of the mensuration of spectrophotometric analysis to study the enzyme activity of Peroxidas, Polyphenol Oxidas, Catalas, Phenylalamine Ammenia-lyase. The result showed that there was definite difference to the metabolic rule of defence enzymes activity in the annual leaf tissue of the resistant and susceptible cultivars after infecting.

茶树抗云纹叶枯病的生理生化机理研究利用分光光度计对茶树叶片中过氧化物酶、多酚氧化酶、过氧化氢酶，苯丙氨酸解氨酶的活性进行了测定分析，结果表明：感染茶云纹叶枯病菌前后，抗病品种和感病品种当年生成叶中防御酶活性变化规律存在一定的差异。

Xanthomonas oryzae pv. oryzae, the casual agent of bacterial blight of rice, is one of the most important pathogens of rice in the world, and a bacterial pathogen model to study the plant-pathogen interactions.

The identification of tea plant resistance to tea brown blight The resistance of 13 tea plant cultivars to tea brown blight had the difference or remarkable difference. In general, the resistance of big leaf cultivars was relatively weaker, the resistance of middle leaf cultivars was relatively stronger.

茶树品种抗云纹叶枯病的鉴定 13 个茶树品种对茶云纹叶枯病的抗性存在显著差异，一般大叶种材料的抗性较弱，中叶种材料的抗性较强。

Aim at the influence factors about special field, cultivation system and cultivating level of rice in Shanghai farm, I studied characters of rice stripe blight occurrence on the Farm, investigated the disease resistance level and yield lose rate of different rice cultivars planted on the Farm, and made the suggestion about a synthetical control strategy for the disease in priority to adopt rice cultivars with resistance to the disease. Through investigation for the actuality of plant protection in Shanghai Farm and the examination of medicament for the disease, I gave an advice about the best chemical controlling method for the disease.

本研究的目的和方向：针对上海农场这一特殊地域因素、栽培制度、种植水平等因素的影响来研究农场水稻条纹叶枯病的发生特点；通过调查与试验上海农场不同品种的抗病性及产量损失，从而提出推广抗病品种的防治策略；通过调查与试验上海农场栽培制度下条纹叶枯病的发生特点，从而根据上海农场的特点提出综合防治的策略；通过对上海农场现有植保状况的调查与药剂试验，从而提出最佳化学防治方法。
