中文摘要：以江苏淮北麦区主推中筋小麦淮麦19和强筋小麦烟农19为材料，研究了高、中、低肥力稻茬田上施氮量对小麦籽粒产量和物质生产的影响。

The optimum carbon source of the pathogen for the hypha growth and conidiophore bearing was amylomaltose, the optimum nitrogen source was yeast extract and the alternation of light and darkness could promote the hypha growth.

菌丝生长及产孢的最适碳源为麦芽糖，最适氮源为酵母膏，光暗交替有利于菌丝的生长。

The optimum pH is 8-10 for hypha growth and 7-9 for conidiospore germination; The hypha could not grow on the culture medium which nitrogen source comes from urea and asparagines, but it could grow fast and produce more conidiospore on the culture medium which carbon source comes from maltose, glucose and lactose, and nitro0gen source come from glycine, histidiane and peptone.

该菌在PH 4~12范围内均能生长、产生分生孢子并萌发，菌丝生长的最适pH 8~10。，孢子萌发的最适PH 7~9；该菌不能在以尿素和天门冬酰氨为氮源的培养基上生长，但以麦芽糖、葡萄糖、乳糖、淀粉、甘氨酸、组氨酸和蛋白陈为碳源和氮源时，菌丝生长快、产孢量大；光照处理对该菌菌丝生长、产孢和孢子萌发无显著影响。

The results showed that the best carbon source was sucrose in which sporulation (16.13×10^7 conidia/cm^2) and extracellular protease 117.38 μg/(minmL reached the highest. The bean cake was the best nitrogen nutrition in which the quantity of conidium (15.62×10^7 conidia/cm^2) and extracellular protease 74.01 μg/(minmL were much higher than that of the contrast and inorganic salts.

综合各项指标得出，HFW-05菌株生长的最适碳源为蔗糖，产孢量与产酶量最大，分别为16.13×10^7孢子／平方公分和117.38μg/；最适氮源为豆粕粉，其产孢量和酶活远高于对照和无机盐类，分别为15.62×10^7孢子／平方公分和74.01μg/。

Because positive clones utilizing nitrate or nitrite as sole nitrogen source werentdirectly isolated from the genomic library, random miniTn5 insertion mutant library wasconstructed via biparental conjugational transfer between E.

由于不能从文库直接筛选到利用硝酸盐的阳性克隆，因此，通过Tn5插入突变构建了随机插入突变库，采用E。

Consistency varied with diffierent experimental conditions, with increasing the total amount of nitrogen in specific range.

在一定施氮量范围内，汕优63、武育粳3号的胶稠度随着总施氮量的增加而显著上升。

Of or relating to or containing nitrogen.

含氮的或与之相关的。

The total nitrogen concentrations in thirty soil samples collected from thirty regions in China and digested by concentrated H2SO4 with catalyzer were analyzed by a continuous flow injection analyzer and traditional Kjeldahl method.

采自全国30个地区的30个土壤样品经H2SO4-催化剂消解后，分别用流动注射法和凯氏定氮法测定全氮含量。

In the rabbit the utilization coefficient of urea nitrogen was as high as 20.7%, due to the effect of microflra in the caecum and behavour of coprophagy.

实验1巧只体重Zkg左右的雄性新西兰白兔，随机分成三组，分别一次性用尿素灌胃4.59//只，9留只和13.5创只，约占兔正常采食量的3%、6%和9%。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
