查询词典 terra incognita

It is concluded that soil solarization with transparent film mulch and cow dung amendment is promising in increasing soil temperature to the extent needed to control Meloidogyne incognita population within 30cm soil depth in the study area.

故覆盖透明膜和添加牛粪可显著提升30cm深度内的土壤温度，利用太阳能加热可望降低土壤中根结线虫种群数量。

They belong to Meloidogyne incognita or Meloidogyne arenaria.

因此，这12个根结线虫种群属于花生根结线虫或是南方根结线虫(M.incognita)。

The parasitic rates of 10 of the 76 isolates were over 50%. As for Paecilomyces lilacinus, Verticillium chlamydosporium and V.lamellicola, the parasitism to eggs had no obvious difference among M.incognita, M. arenaria and M.javanica, which indicated that these 3 fungal species may be effective agents for control of root-knot nematodes.

通过测定，76个菌株中有10个菌株对南方根结线虫卵的寄生率超过50%，种间及菌株间对卵的寄生能力存在很大差异；Paecilomyces lilacinus， Verticillium chlamydosporium及V.lamellicola对Meloidogyne incognita， M.arenaria和M.javanica卵的寄生能力进行比较，在3种线虫之间没有明显差异，说明这3种真菌对这3种根结线虫有进行防治的可能性。

According to sequence cluster analysis of the the tested samples, it indicates that the gene distance of RKN-9, RKN-8, RKN-21, RKN-11, RKN-18 , RKN-20, RKN-17, RKN-22, RKN-23, RKN-24 and RKN-25 to Meloidogyne incognita and Meloidogyne arenaria was very close with homology of 100% and 99%, respectively.

根据25个根结线虫种群序列比对分析和聚类分析可知，河北廊坊的番茄根结线虫、安徽宿州的黄瓜和番茄根结线虫、安徽太和的桔梗根结线虫、安徽和县的番茄根结线虫、浙江杭州的黄瓜根结线虫、四川成都的番茄根结线虫、安徽泗县的黄瓜根结线虫和中国农业大学四个不同番茄品种上的根结线虫的序列之间同源性为100％；它们与花生根结线虫和南方根结线虫(M.incognita)的遗传距离最近，序列同源性分别达到100％和99％。

RDNA-ITS sequence analysis of 30 populations showed that there is difference among M. incognita, M. hapla, M. arenaria, M. javanica, M. panyuensis, M. zhanjiangensis. and M. hainansis, whereas little rDNA-ITS sequence difference among three normal Meloidogyne species.

通过对30个种群的rDNA-ITS序列分析，发现番禺根结线虫、海南根结线虫、北方根结线虫、湛江根结线虫、南方根结线虫、爪哇根结线虫和花生根结线虫种间的DNA-ITS区碱基序列存在差异，但后3种常见种之间差异小。

And RW pathogen material impact on promoting corruption, the result shows : RW promoting corruption in simulated conditions, the number of male live Meloidogyne incognita, the number of females and 10 days respectively reduction in the number of oocysts 61.31%, 48.51%, 49.22%; Pathogens in tobacco black shank (Phytophthora nicotiana Breda de Haan), cercospora leaf spot pathogen were lower 97.68% and 97.77%.

与RW促腐剂对病害病原物影响对比，结果显示：RW促腐剂在模拟条件下，使活体根结线虫雄虫数、雌虫数、卵囊数在10d内分别减少61.31%、48.51%、49.22%；使烤烟黑胫病病原菌(Phytophthora nicotiana Breda de Haan)、角斑病病原菌分别比对照减少97.68%、97.77%。

So the strategies defend against the Meloidogyne incognita infectivity were focus on the pathogenic genes and its products, which may provide insights into the adaptations required by metazoans to successfully parasitize and counter defenses of immunocompetent plants.

因此研究工作的重，改转向研究南方根结线虫寄生相关基因及其产物上。这些研究有助于深入了解其成功寄生和突破植物免疫防御的机理。

Through the dinosaur remains, the dream for the technology of the Pleiadian scientists was anchored upon Terra from Alpha Centauri.

通过恐龙遗骨，昴宿星科学家的科技之梦从半人马α星球被锚定在Terra上。

Amphora was the unit of measurement that determined the amount held by the large terra cotta jars that were used to ship grain, spices and wine.

Amphora是一种度量单位，它是用来计量一种用来装运粮食、调味品和酒的大型陶瓷瓶的内容量的。
