查询词典 blight

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。

In the green asparagus field, the severest disease is Stem Blight, the next is Brown Spot.

绿芦笋病害以茎枯病为最严重，其次是褐斑病，间有萎凋病发生。

Bryoniae could be used as early indicator in screening the melon germplasm for the resistance to gummy stem blight.

POD活性变化与甜瓜蔓枯病抗性有密切关系，可作为早期筛选抗性种质的辅助指标。

To understand the relationships between the activities of superoxide dismutases, catalase, peroxidase and resistance of melon to gummy stem blight, dynamic changes of activities of SOD, CAT and POD in resistant accession PI 196477 and susceptible accession Lvbaoshi were analyzed after inoculation by Didymella bryoniae.

为了明确甜瓜蔓枯病抗性与SOD、CAT和POD活性变化的关系，采用甜瓜蔓枯病菌孢子悬浮液对抗病材料PI 196477和感病材料绿宝石进行接种，并于接种后测定叶片内SOD、CAT和POD的活性变化。

Through marker-assisted selection in self-cross populations we obtained transgenic restorer line T773 carrying three genes (cry1Ab, bar and Xa21) with resistance to bacterial blight, striped stem borer and herbicide.

2利用Tail-PCR技术获得转基因水稻中外源cry1Ab基因插入的侧翼序列，通过序列比较分析确定了转cry1Ab基因在水稻基因组插入的物理位置。

And the lesion number of severest diseased stem is over 100, the percentage of disease in Brown Spot is around 60%. From the result of fungicide test, we know the Difolatan, Benlate and Orthocide are the more effective for controlling Stem Blight, but the percentage of prevention don't reach the perfect effect. The effect of other fungicides is not good. So we must continue to work to search for safe, and ideal fungicides as the index of prevention.

由药剂试验结果，以Difolatan（预防率：100p.p.m为80.95%，200p.p.m为83.33%），Benlate（预防率：100p.p.m为85.71%，200p.p.m为92.85%），Orthocide（预防率：100p.p.m为71.42%，200p.p.m为73.80%），三种药剂对茎枯病之防治效果最佳，但预防率未达百分之百，其他药剂之防治效果不佳，故仍需进一步寻求安全、有效之防治药剂，以供今后笋农防治茎枯病之依据。

Breeding of transgenic rice restorer line for multiple resistance against bacterial blight, striped stem borer and herbicide(1) Transgenic rice line Zhongguo91 (carrying cry1Ab and bar gene) and elite restorer line Hui773 were crossed, then backcross was carried out three times using Hui773 as recurrent parent and self-cross was carried out one time.

多抗性(抗白叶枯、螟虫、除草剂)转基因水稻恢复系的培育(1)将恢773与携有转cry1Ab和bar基因的水稻新品系中国91(cry1Ab)杂交，并以恢773作为轮回亲本，连续回交三代和自交一代，对各回交世代的单株进行cry1Ab和bar基因的PCR分析、田间抗虫性鉴定和除草剂Basta抗性鉴定，经过选择获得了转基因水稻恢复系T773-1，田间种植对螟虫及除草剂Basta表现很好的抗性。

As part of its drive to spur an economy blight ed by feeble consumer confidence after last year's military coup, the Bank of Thailand lowered its policy interest rate by 0.25% to 3.25%, its fifth rate cut this year.

泰国央行减息四分一厘至3.25%，是今年第五度减息，旨在刺激去年军事政变后的疲惫消费信心。你知道它的英文吗？
