有五种方法用于水利灌溉：土地漫灌，垄沟灌溉，喷洒法，地下灌溉和滴灌法。

There are five methods of applying irrigation water to fields-flooding , furrow irrigation , sprinkling , sub-irrigation , and trickle irrigation .

之所以地下灌溉系统更适合番茄栽培，还有几条理由。地下灌溉使土表保持干燥。

There are other reasons why the underground irrigation system is better for tomatoes . Underground system leaves the surface soil dry .

对局部控水灌溉&无压根区地下灌溉技术从理论上进行了分析，并给出了其边界条件下的土壤水分运动方程。

The law of outlet flow rate at different aperture diameters and the soil water status under the condition of non-pressure irrigation were studied .

对地下灌溉水测井的监测结果表明，有个别地下灌溉井单项指标超标，但所测井的综合污染指数均远远小于1，对地下水环境未造成不利影响。

For underground water , monitoring results indicated that water 's comprehensive pollution index was less 1 , so the underground water environmental was good .

这些和其他的主要湿地已经失去了其历史上水储量的大半，并经历着地下灌溉排放物污染严重的冲击。

These and other major wetlands have lost most of their historic supplies of water and some have also experienced serious impacts from contaminated subsurface irrigation drainage .

结果表明：地表灌溉水、地下灌溉水水质综合污染指数均小于1，但有升高的趋势；

The result shows that the comprehensive pollution index of the surface and underground irrigation water is less than 1 , but there is a trend of rising .
