灌溉

Soil water content, water store and their range of variation increased with the amount of irrigation increasing, and affected soil deep layer.

在灌溉量相同的情况下，随着氮肥施用量的增加，氮素淋失的可能性明显增加。

It was two hours, owing to sundry wrong turnings, ere she found herself on a summit commanding the long-sought-for vale, the Valley of the Great Dairies, the valley in which milk and butter grew to rankness, and were produced more profusely, if less delicately, than at her home - the verdant plain so well watered by the river Var or Froom.

由于拐弯时多走了一些冤枉路，她走了两个小时才走到一个山顶上，望见她渴望已久的沟谷：大奶牛场的沟谷。在那个沟谷里，牛奶和黄油的增长十分迅速，虽然不如她家里的牛奶和黄油味美，但它们的生产要远比瓦尔河或佛卢姆河所灌溉的那块翠绿草原上生产的牛奶和黄油丰富。

Completion of the project, together with those in 2008 before the implementation of the reconstruction project, Bayannur City Hetao irrigation area of 787 hectares of existing irrigation Yellow fundamental transformation will be completed, can add 50 million mu of cultivated area ; Yellow River Irrigation District water will be reduced by 1.2 billion cubic meters, equivalent to savings of 12 large reservoirs (according to the criteria for the classification reservoir, storage capacity up to 100 million cubic meters is large reservoirs); the annual grain production capacity can add three billion kg, close to irrigation district The current annual production of 3.8 billion kg of grain, and create a "granary north of the Great Wall."

项目完成后，连同2008年以前实施的改造项目，巴彦淖尔市河套灌区现有的787万亩引黄灌溉农田将基本改造完毕，可新增种植面积50万亩；灌区引黄水量将减少12亿立方米，相当于节省出12座大型水库(按水库划分标准，库容达1亿立方米就是大型水库)；每年可新增粮食生产能力30亿斤，接近灌区目前的粮食年产量38亿斤，再造一个"塞外粮仓"。

In a word, according to the research of pulp wastewater treatment using pond-reed system, we discovered that the complex system can removal wastewater pollutants effectively, at the same time, the salinity of soil is dramatic decreased through wastewater washing, which bring many active results: increasing of N, P, and organic matter; enhancing of soil microbes, enzymes, MBC/TOC, and soil respire rate; increasing of reed height and yield, decreasing of weed diversity; affecting of transporting ability of Ca, Mg, K, Zn, and Mn , and improving of water shortage, salinity resistance and rhizosphere metabolized secretion conditions, all those improved the weak ecosystem.

总之，经过对生物塘-芦苇湿地系统处理造纸废水的研究，发现系统能有效去除废水中有机物，同时废水灌溉还极大的降低了土壤盐分，产生了一系列积极效应：系统内氮、磷、有机质增加；土壤微生物和酶活性增强；MBC/TOC及土壤呼吸强度提高；芦苇株高和产量增加，而杂草的多样性减少；同时也会影响系统内钙、镁、钾、锌、锰等离子迁移，改变系统受盐碱和缺水胁迫的现状和根际代谢状况，极大地改善了滨海盐碱生态系统现状。

These institutions responsively guaranteed the performance of these three phases. This paper takes the analytical framework of "infrastructure---participators' character---institutional environment" to discuss the form of ...

本文采用以"灌溉设施的物质属性--参与者特质--制度环境"为三个权变因素的制度分析框架对这三种制度安排的产生与有效性进行了分析，得出了有效的制度安排取决于权变因素之间互相匹配的结论。

This system is designed using passive water harvesting irrigation on the edges of the river bed.

这个系统被设计在河床边缘，通过吸收河水得到灌溉。

Under different irrigation methods, such as small-pipe-flow irrigation and flooding irrigation, a study was conducted on Robinia pseudocacia L.

在小管出流与大水漫灌不同灌溉方式下，研究刺槐Robinia pseudocaciaL。

If this runoff water can be accumulated it can be used for farming.

如果这些流失的水能够积蓄起来，它们就可以用来灌溉。

Thanks to modern irrigation, crops now grow abundantly in areas where oncecacti and sagebrush could live.

受当代灌溉之赐，农作物在原来只有仙人掌和荞属科植物才能生存的地方旺盛的生长。

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