灌溉

Salt stress is the primary effect that limits and decreases the output of crops in many parts of the world, particularly irrigated land.

土壤盐分是制约作物产量的主要因素，它可使作物尤其是灌溉农业的作物减产。

The Computer Analysis Technique is used to analyze the structure of surface irrigation simulation model srfr firstly, and then the srfr is connected with the Genetic Algorithm model, to consist of self-contained parameter optimization inverse program.

用计算机解析技术对地面灌溉数值模拟程序srfr进行了解析，然后把经过解析后的模拟程序与遗传算法程序进行连接，形成了一个完整的参数优化反求程序。

In general, the decline of American Laissez-faire at the end of nineteenth century, conservation movement and the dream that Progressionist searching for rebuilding Safety valve of West are the reasons The National Reference policy not only exert a great influence on west conservation and deep economic exploitation, but also on the administration power of federal government expansion.

The results showed that length from flag leaf pulvinus to spike base has the largest coefficient of variance of 42.1% and 37.2% in both DS and WW environments, respectively, while the spikelet per spike has the smallest CV of 6.4% and 5.7%. Under different water regimes, spike number per plant, effective spikelet per spike and peduncle length contribute a lot to the stable grain yield. Genetic diversity indices of DTI were from 1.95 to 2.07, with an average value of 2.02. Based on the DTI of agronomic traits, all accessions could be clustered into seven groups, the first and third groups are not sensitive to the water regimes, and the second group is more suitable for planting in dryland.

结果表明：在雨养和灌溉条件下，穗叶距的变异系数最高，分别为42.1%和37.2%，单穗总小穗数的变异系数最低，为6.4%和5.7%；不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；性状耐旱指数的多样性指数在1.95到2.07之间变化，平均值为2.02；根据性状耐旱指数将供试材料分为7个类群，其中第I、第III类群材料表现为对水分条件不敏感，而第II类群材料更适于在干旱条件下种植。

Offering a solution, Dutch designer Bas van der Veer has come up with an innovative rain barrel named "A Drop of Water" that possibly filters and stores rainwater in a watering can, which can further be used to water your home garden.

为了解决这一问题，荷兰的设计师 Bas van der Veer 提出一种创新的雨桶，名为"一滴水"，可以在一个浇水桶内过滤和贮存雨水。这些雨水能再次被利用，以灌溉家庭菜园。

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