灌溉

The crop is salicornia. It is nourished by seawater flowing from a man-made canal.

这种作物就叫做盐角草属，由一条人工开凿的运河引海水灌溉滋养成长。

Based on the field experiment data of winter wheat blending irrigation by saline water in Nanpi Ecological Agriculture Experimental Station of the Chinese Academy of Sciences from 2002 to 2005, the effects of blending irrigation with mineralization of 0.84, 3, 4 and 5 g/L on the soil salification rate, soil sodium adsorption ratio of soil saturation extract as well as winter wheat yield and yield constitute factors irrigated were studied in order to determine upper limit of irrigation mineralization suitable for the location.

根据中科院南皮生态农业试验站2002～2005年的冬小麦微咸水混灌田间试验资料，以淡水为对照研究了矿化度分别为3、4、5 g/L的微咸水混灌对土壤积盐率、土壤饱和浸提液钠吸附比、冬小麦产量和产量构成因素以及水分利用效率的影响，从而确定适宜的灌溉水矿化度上限。

But as the special geological condition,irrigation causes a series of problems of agroecological geology,such as landslide,salination and so on.

长时期的引水灌溉使土壤理化性质发生改变，并由此引发了地裂缝、滑坡等地质灾害，同时地下水水位的上升，使地表土壤盐渍严重。

In accordance with the prevention of soil salination and water-saving irrigation in autumn in Inner Mongolia Hetao irrigation district, the reasonable water-saving irrigation scheme in autumn was quantificationally established by using SHAW model in theory, which aimed at the different salinized soils.

根据内蒙古河套灌区秋浇节水与土壤盐渍化防治的需要，利用SHAW模型模拟确定了不同盐渍化土壤合理的秋浇节水灌溉制度。

Under the good drainage condition, when degree of mineralization in the return water was less than soil salineness, irrigation with the return water can make soil desalinited evidently.

通过利用低矿化度回归水的土柱模拟实验研究表明，在排水较好条件下，含盐1.3—1.6g／L的低矿化度回归水灌溉可使中轻度盐渍化土壤脱盐。

Soil salineness increased gradually along with irrigation by the return water.

但随灌溉年限延长含盐量逐年增高，含盐量、SSP、SAR、Cl－的量与回归水中该值呈显著正相关。

The result is of importance significance for the reliability of water supply during irrigation periods and the control methods of reservoir operation based on the concept of pollutant sluicing before water supply.

对以后农业灌溉期水库供水安全保障措施实施以及&先冲污后供水&的水库供水运行调度方案制订，具有重要的指导意义。

"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。

Through terracing of rainfed area of 72,272 mu, 57,921 households benefited from improved crop production.

同时改建的72，272亩无灌溉条件的梯田使57，921农户受益。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
