the machine. He said that during cultivation, rice requires complete submersion in a layer of water 10-15 cm above the soil surface, which demands huge amounts of water and fertilizers.</p> <p>He designed the soil and water management machine to tackle this. The machine makes ‛V’ shaped lines into the soil, at a depth and width of 20cm, and sows rice seedlings automatically. This operation maintains the water level necessary for rice to grow in the V-shaped troughs, which is less than the water used in conventional agriculture that requires the entire plot of land to be completely submerged.</p> <p>The machine was tested in a field in Kafr el-Sheikh governorate, which is known for rice crop cultivation in Egypt, with good results. It reduced the amount of water used by half, and “the crop yield increased by 4.6 per cent,” Al-Hagary said.</p> <blockquote class="quote list-right"> <h3> “This machine will save a lot of irrigation water in Egypt each year, which will help the country face these challenges and direct the water saved towards cultivating other crops.”</h3> <h4> Khaled Ghanem, Al-Azhar University</h4> </blockquote> <p>Atef Sweilem, water management and irrigation expert at the International Center for Agricultural Research in the Dry Areas, (ICARDA), praised the machine, but added that “saving water and fertilizers would not tempt small farmers to buy it, as the increase in the yield was not huge”. He pointed out that the rice agricultural plots owned by most farmers do not exceed half an acre.</p> <p>“Saving water and fertilizers does not mean much for farmers, who get water for free and fertilizers subsidized by the state,” Sweilem explained.</p> <p>Therefore, he believes that Egypt’s ministries of Agriculture and Water Resources and Irrigation should play an important role in supporting farmers financially and with training in using the machine.</p> <p>Al-Hagary said the machine costs about US$5000, but needs further development before it is ready for commercial production.</p> <p>He intends to re-submit a proposal to the Academy of Scientific Research and Technology in Egypt, hoping it would support further development of the innovation. An earlier proposal made in 2014 went unanswered, and he had to design it at his own expense.</p> <p>Ghanem believes that “Egypt needs to use this machine widely range for several reasons,” the most important of which is the implications of Ethiopia’s Renaissance Dam on Egypt's share of water. He also referred to the effects of climate change including drought, desertification, and an increase in evaporation rates, as well as the water wasted along the Nile.<div class="related_widget"><h3 class="widgettitle">You might also like</h3><ul><li><a href="//www.caisenvip.com/global/news/ethiopian-dam-deal-ignores-science-warn-experts/">Ethiopian dam deal ignores science, warn experts</a></li><li><a href="//www.caisenvip.com/global/multimedia/ethiopia-millennium-dam-science-controversy/">Ethiopia’s Millennium Dam: Science and controversy</a></li><li><a href="//www.caisenvip.com/global/data-visualisation/africa-hydropower-future-interactive/">Africa’s hydropower future</a></li><li><a href="//www.caisenvip.com/global/scidev-net-at-large/plan-hydropower-stations-future/">How to plan hydropower stations for the future</a></li><li><a href="//www.caisenvip.com/global/news/egyptian-filters-seawater-environment/">Egyptian method filters seawater in minutes</a></li></ul></div>“This machine will save a lot of irrigation water in Egypt each year, which will help the country face these challenges and direct the water saved towards cultivating other crops,” Ghanem said.</p> <p>He added: “The concerned ministries might not pay attention to this innovation.

[开罗]埃及的专家和利益相关者警告埃塞俄比亚文艺复兴时期的迫在眉睫的水贫困，这将成为现实。同时，农业生产消耗了该国85％的水资源，其中一半用于水稻灌溉。

稻草种植每年消耗超过100亿立方米的水，或埃及尼罗河水的六分之一以上。scidev.net。他解释说，这并不能说明未经授权地区耕种的水，估计约为授权区域的三分之一。

但是，可能有一种解决方案，以机器的形式以一种节省通常用于灌溉的水量的一半量和四分之一的肥料。一个特殊进口的单元，机械地播种大米幼苗，安装在机器上。

The machine’s Egyptian inventor, Mohamed El-Sayyed El-Hagarey, a researcher at the Desert Research Center in Cairo, was granted the prestigious WatSave Award for Young Professionals from the International Commission on Irrigation and Drainage (ICID) during the Second World Irrigation Forum held in Thailand in mid-November.

水稻种植每年通过传统方法消耗超过100亿立方米的水

播种稻幼苗机械的价格为每英亩400美元，同时播种费用为150美元

新机器以节省通常用于灌溉的水量的一半的方式耕种田地，并在耕种中使用了四分之一的肥料，并且在播种幼苗中花费了很多时间

该机器以20厘米的深度和宽度将‛v'形状的线条进入土壤，并自动播种稻幼苗

V形槽维持大米生长所需的水位，但在常规农业中使用的水少于需要全部土地的整个土地。beplay下载官网西西软件

该机器还将作物产量提高了4.6％

在接受采访scidev.net，El-Hagarey解释了他发明机器的动机。他说，在耕种过程中，大米需要在土壤表面10-15厘米的一层水中完全浸没，这需要大量的水和肥料。

他设计了土壤和水管理机器来解决这个问题。该机器以20厘米的深度和宽度将v'形状的线条进入土壤，并自动播种稻幼苗。该操作维持水平在V形槽中生长所需的水位，这比常规农业中使用的水少，该水需要完全淹没的整个土地。beplay下载官网西西软件

该机器在Kafr El-Sheikh省的一个领域进行了测试，该局以埃及的水稻种植而闻名，结果良好。Al-Hagary说，它将使用的水量减少了一半，“农作物产量增加了4.6％”。

“这台机器每年将在埃及节省大量的灌溉水，这将有助于该国面对这些挑战，并将节省的水转向种植其他农作物。”

在干旱地区国际农业研究中心（iCarda）的水管理和灌溉专家Atef Sweilem对机器的称赞，但补充说：“随着增加的水和肥料的增加，随着饮水和肥料的增加，随着小型农民的价格增加，随着该机器的增加产量不大”。他指出，大多数农民拥有的稻米农业地块不超过一半英亩。

Sweilem解释说：“节水和肥料对农民免费并没有多大意义，他们免费获得水，并由该州补贴的肥料。”

因此，他认为，埃及的农业和水资源部以及灌溉部应该在为农民提供资金和使用机器方面的培训方面发挥重要作用beplay下载官网西西软件。

Al-Hagary表示，该机器的成本约为5000美元，但需要进一步开发才能进行商业生产。

他打算重新提交埃及科学研究与技术学院的提案，希望它能够支持创新的进一步发展。2014年提出的较早提议没有得到答复，他不得不自费设计。

加纳姆认为，“埃及需要多种原因使用该机器，”其中最重要的是埃塞俄比亚文艺复兴时期大坝对埃及水的份额的影响。他还提到了气候变化的影响，包括干旱，荒漠化和蒸发率的增加以及沿尼罗河浪费的水。

Ghanem说：“这台机器每年将在埃及节省大量的灌溉水，这将有助于该国面对这些挑战，并将节省的水转向种植其他农作物。”

他补充说：“有关的部委可能不关注这项创新。解决方案是建立主要公司，以销售类似的创新，这些创新可以由低价股票资助，从而向更多的消费者提供。”
