灌溉

The results indicated that the optimum depth of ponding water was 9cm, and the optimum water management regime was variable irrigation.

最后，运用该系统模拟了不同表层水深度和水分管理模式下的水稻产量，模拟结果表明，最适表层水深度为9cm，最佳水分管理模式为变化灌溉。

This model considered many factors affecting the growth of maize, such as irrigation, rainfeed, CO_2 fertilization and predating the planting date by 5 days and 10 days when analyzing the change of yield and period duration. It further indicated how the production of maize was affected by the increase of CO_2 and PAR by using the data collected from the field experiment in Changping Experimental Station of China Agricultural Academy of Sciences.

模拟时分别考虑了灌溉、雨养、CO_2的肥效作用、播种期提前5天和10天条件下玉米的产量和生育期的变化情况，同时利用在中国农业科学院昌平试验站所做的田间试验结果进一步说明CO_2升高以及光强增加对玉米生产的影响情况。

This is discovered and put forward firstly by this paper, it established theory base for seting up the binary structure improvement tier alkaline soil improving, and a bit of times without number washing flooding. In improvement process of alkaline soil, the seepage capacity of gypsum was preponderated over 40% than the used capacity of gypsum.

关于石膏混合层与非混合层，在土壤改良过程中，各自具有不同量变到质变的规律，是本文首先发现并提出来的：它为建立碱土改良的二元结构计划改良层并与小定额分次冲洗相结合灌溉，奠定了理论基础。

Beginning with the configuration effect of price on agricultural water resources,the authors analyzed the current price problem of agriculture water saving and prognosticated the inevitable trend of feebased agricultural water in china.

我国的农业灌溉用水过程中，除渠灌区的农业用水目前已经收取一部分水费外(此费用实际上为部分水利工程费用)，在井灌区的农业用水很多地方还未收取水费。

One of the systems that is used on smaller ranches is the use of "hand move" irrigation systems.

对于较小的土地有一种叫&手动&的灌溉系统。

He who is full, refreshes others.

充满了之后，才能灌溉他人。

More assimilation products were stored in sheathes than those in leaves. 2After rewaterring, net photosynthetic rate and evaporation rate came back quickly, especially D3 and D6 groups whose two photosynthetic indexes were higher than that of control group and then droped back to normal in serveral days.

同化产物在叶片中的含量高于茎鞘，但叶片中的氮素含量低于茎鞘。2恢复灌溉后，受到胁迫的处理组的光合速率、蒸腾速率都迅速升高，干旱3 d和6 d的处理组光合水平超过对照，然后又有所下降，水分利用效率因为蒸腾速率的骤然升高而降低，之后有所恢复。

The solution, Mr Chartres and others contend, is more efficient use of water or, as the sloganeers put it,"more crop per drop". Some 1.2 billion people, about a fifth of the world's population, live in places that are short of water.

应对之道是以Chartres为首的人声称的对水资源更充分的利用，或是标语作者声称的&用一滴水灌溉更多的庄稼&。12亿左右的人口，约占世界人口的五分之一，生活在缺水地区。
