查询词典 stripe blight

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。

In this research, using the Oligosaccharides derived from plant cell walls as inducers, we examined whether they can induce the resistance to powdery mildew, head blight and stripe rust of wheat.

本研究以自行设计的方法从植物细胞壁中提取低聚糖，以其为诱导剂，研究其对小麦白粉病、赤霉病和条锈病的诱病导抗性效果。

Oligosaccharides could induce obvious resistance to powdery mildew, head blight and stripe rust of wheat. However, the effects on different diseases are quite different due to Oligosaccharides derivation, time for enzyme extraction and the concentration used.

研究表明，所用提取物可以诱导小麦产生对白粉病、赤霉病和条锈病的抗性，但不同来源、不同的酶解时间和不同使用浓度的低聚糖在不同病害上的诱导抗病性效果差异很大。

The highest relative defense effect on different diseases were analyzed: 88.61 percent (NO.5 at 50ppm) against powdery mildew, 77.63%(NO.5 at SOppm) against head blight. Although the RDE against stripe rust is lower than the formers, NO.5 at SOppm can induce obvious HR on wheat leaves.

对小麦白粉病的防治效果最高可达86.61％(5号100ppm)；对小麦赤霉病的防治效果最高也有77.63％(10号100ppm)；并发现50ppm的5号提取物处理后能使感染条锈菌的小麦产生明显的过敏性坏死反应。

Thus, prevention and cure for rice stripe blight has become an important object in Shanghai farm.

因此，水稻条纹叶枯病的防治以成为上海农场的重要课题。

Rice stripe blight is a virus disease introduced mainly by Laodelphax striatellus Fallen. Rice stripe virus is a RNA virus and one of Tenuivirus members.

水稻条纹叶枯病是由水稻条纹病毒(Rice stripe virus，RSV)引起的一种病毒病，其传播介体主要是灰飞虱。

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。

Rice stripe blight occur only bits and pieces and didnt result in obvious harm from 2001 to 2003, and quantity of Laodelphax striatellus Fallen was very low and only in part place it was more serious.

从2001年至2003年条纹叶枯病一直处在零星发生状态，未构成产量威胁，灰飞虱的发生也一直处在低值状态，仅局部地方发生较重。

Along with increase of infecting area and diseased plant rate year after year, the harm of rice stripe blight reached peak in 2005 and resulted in serious rice yield reduction. Yield of Wuyujing series cultivars was reduced about the 50 percent and there was almost no any output in some farmland.

发病面积逐年上升和发病率逐年提高。2005年更是达到发生危害的高峰，造成水稻严重减产，武育粳产量损失达到50％左右，严重田块几乎绝收。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
