"Drawing water from Disi to Amman is just a temporary solution," Minister of Water and Irrigation Raed Abu Soud said at a ceremony attended by representatives of GAMA Energy, a Turkish firm that will handle the project.

在一个GAMA Energy代表出席的典礼中，水利暨灌溉部长索特表示：「从迪斯引水到安曼只是暂时的应急方法。」土耳其的公司会执行这个工程。

Grain yield per hectare is the most important factor in the method of the gray system analysis. There was significant correlation between effective irrigated area, the amount of fertilizer applied, mechanical power and the grain yield. The area of grain and the population of agriculture are factors that affect grain production. The correlation coefficient of natural resources and grain production changes unstably.

单产与粮食产量始终保持很高的关联度；有效灌溉面积、实际机耕面积、化肥施用量、农村用电量和农机总动力等农业投入对粮食产量提高影响重大；耕地面积和劳动力对粮食产量具有一定的制约；自然条件与粮食产量的关联度剧烈变动。

In this paper,thetype of flow in perforated pipe was analysed,and the influence of which on calculating waterhead losses was simulated by computer programme.

大量计算表明，灌溉中使用的小流量多孔管的首端流态一般是紊流光滑区和紊流过渡区，而在末端或多或少出现一定长度的层流段。

The irrigation infrastructures still have to work, which was in contradiction with the Family Contract Responsibility System.

人民公社是低效率的，但通过其超强的政治动员能力、意识形态等要素成功地克服了灌溉基础设施供给中的&搭便车&问题。

A UN environmental assessment of the country estimates that productivity could be doubled on the land currently farmed, while another 10% of Afghanistan (approximately 62,000 square kilometres, or 24,000 square miles) could be brought under the plough through irrigation.

联合国的环境评估认为，如果阿富汗那10%无人耕种的土地（有将近62000平方千米，或者说24000平方里）能够被开垦和灌溉，那该国的生产力将能翻倍。

As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.

在传统灌溉-优化施肥条件下，冬小麦单位面积总分蘖数比传统水肥减少，成穗率降低，单位面积穗数有所减少，穗粒数、千粒重无显著性差异；株高基本无变化；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期叶面积指数略低于传统水肥；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟形成的干物质量增加；旗叶、倒2叶倒3叶、倒4叶叶长及总叶面积有所减少，叶片相对增厚；冠层平均叶倾角大，消光系数小，冠层各层的透光率较高，株型紧凑；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层总根量与传统水肥也差异不大，但根长密度和根重密度随土层深度递减速度较慢，根系在下层土壤的分布相对增多。

Animal pens, barns and chicken coops will be needed to house livestock and the barns will ideally be configured to accommodate various types of animals.

手工灌溉庄稼的方法（例如，能够将小溪里的水转道而来，若你想尝试水力发电的话，这也会大有裨益的）。

Even so, several countries are going ahead, and Spain, the European Union's driest country, uses some desalinated seawater to irrigate high-value crops in its driest province, Almería.

即便如此，有些国家还是在迎难而上。欧盟最干燥的国家——西班牙在它最缺水的省份，阿梅利亚营建了海水淡化工厂以灌溉那里的高经济作物。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
