抗旱

The Necessity of water saving agriculture in the loess plateau of China is analysized,and main types of regulating soil water techniques are sumed up as follows:accumulating fertileness,crop rotation,intermittent fallowness of soil,drought resistant crop breeding, water saving ,run off agriculture and chemical methods.

分析黄土高原节水农业的必要性，总结出黄土高原农业调水技术主要有 7大类：培肥地力以肥调水，轮作倒茬调水，间隙休闲调水，抗旱育种调水，节水灌溉调水，径流农业调水，化学技术调水；指出在干旱、半干旱的黄土高原地区，利用农业调水技术是粮食增产增收的有效措施和必然趋

As a result, germination rate under osmotic stress and RWC could be considered as good indices of drought tolerance and used for rapid evaluation for drought tolerance of foxtail millet.

谷子种子在甘露醇渗透胁迫条件下的相对萌发率与幼苗在适度控水条件下相对含水量的变化趋势一致，初步认为这两个指标可以作为苗期快速鉴定谷子抗旱性的筛选指标。

The result of Principal Component Analysis indicated that 6 principal components could present 90.71% information of the raw data of the traits related to drought tolerance of foxtail millet.

主成分分析结果表明，6个综合主成分可代表谷子抗旱性90.71%的原始数据信息量。

Five foxtail millet varieties, including Lu 7060, Yangjiaohuang, Yugu No.

报道了在苗期快速鉴定谷子品种抗旱性的实验结果。

Y pretreatment on their leaves, the physiological effects of vitamin C, ethanolamine, cysteine, fucose and sodium benzoate were studied through design of randomized block and subordinate function values, and three best performance on improved its drought resistance chemicals were selected.

幼苗为试材，经叶片喷施药剂进行预处理后用PEG-6000溶液模拟水分胁迫，采用随机区组试验和隶属函数法，综合评价了维生素C、乙醇胺、半胱氨酸、苯甲酸钠和岩藻糖五种药剂对水分胁迫下香蕉幼苗叶片的生理影响，从中筛选出对有效提高香蕉抗旱性效应前列的三种药剂。

I. triloba of Group II possesses some potential useful genes of drought-tolerance, and root rot and other fungous disease resistance. It can grow under the condition of extreme drought and absolute wetness.

研究表明，属于第Ⅱ群的甘薯近缘野生种Ⅰ。triloba能在非常干旱和完全湿润的条件下生存，具有抗旱、抗根腐病和其他真菌病害的潜在遗传基因。

The general manager of Water, than today has attended in Toledo the inauguration of the working days The control of the poured a priority, has specified than the fond drought to practically the whole Mediterranean arch, from Catalonia to Algeciras, besides of to the Guadalquivir's basin, the top part of the Chunk and some points of the basin of the Duero.

这位总经理的水，会比今天出席了在托莱多就职的工作日数的控制范围内倾注了一个优先事项，已指明较热衷于抗旱，以几乎整个地中海拱，从加泰罗尼亚以阿尔赫西拉斯，另外的，以在Guadalquivir ' s盆地，顶部部分的大块几点盆地的

As the major tree species for forestration in Hilly region on the Loess Plateau, Robinia pseudoacacia and Hippophae rhamnoides can only grow normally in habitant with better soil water condition due to the limited drought resistance of H.

作为黄土高原的主要造林树种，沙棘的抗旱性最差，而刺槐的耐旱性最差，它们都要在土壤水分条件较好的生境才能正常生长。

In this study, the TaDREB1 gene sequences were isolated from four hexaploid wheat cultivars, three diploid relative-species and one tetraploid relative-species.

本研究旨在开发TaDREB1基因的SNP标记，同时摸索一种在普通小麦中开发SNP标记的可行方法，为加密小麦的遗传连锁图谱，发掘和利用小麦的优异抗旱种质资源提供一条新途径。

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。

Go down on one's knees;kneel down
