Техника и технология полива комплектом синхронного импульсного дождевания (КСИД-10С)

DUV 2/0.005-10 Water Level Sensor

Мероприятия:

Применяется комплект синхронного импульсного дождевания. Поливная вода предельно равномерно рассредоточивается по всему участку орошаемого пастбищно-сенокосного угодья, который поливается одновременно. При этом подводимый расход воды к импульсному аппарату составляет 0,05-0,3 л/с, к поливному трубопроводу 0,25-2,0 л/с, что сокращает затраты на устройство трубопроводной сети в 3-4 раза по сравнению с обычными системами (комплектами) дождевания. Трубопроводная сеть состоит из труб диаметром от 15 до 25 мм, что значительно облегчает их транспортировку и монтаж в условиях горных склонах.

Технические характеристики:
Режим работы: автоматический и ручной
Площадь полива: 10 га
Водоподача за сутки: до 100 м3/с
Средняя интенсивность дождя – 0,002-0,008 мм/мин
КПД: 99%
КЗИ: 98%
Степень автоматизации полива: 100%

Результаты:

• Осуществлена водоподача в соответствии с потребностью растений в воде с учетом изменяющихся метеорологических условий, запасов влаги в активном слое почвы;
• Исключены: 1) водная эрозия почв, 2) луже-образование и 3) сбросной сток;
• Нет необходимости в водообороте между участками полива.

The DUV 2/0,005-10 Sensor was deployed and demonstrated its efficiency in Jambyl and Southern Kazakhstan Regions.  It allowed to visually and in real-time observe the dynamics of water level fluctuations and completely exclude manual operations and subjectivity in the process of taking readings – a relevant task in the environment of transition to market economy.

Water level sensors were installed in 17 hydro-posts in Southern Kazakhstan Region (Maktaaral District).  In Jambyl Region, the same sensors were installed in 3 hydro-posts in Merke District.

Results:

Technical:

a) immediate data exchange on water volume passing through every water lead to the fields of agricultural producers (farms) as well as automatic transfer of this information to stakeholder organizations (branch of “Kazvodkhoz” Republican State Enterprise (RSE), etc.);

b) archiving the data coming from hydro-posts with its subsequent processing in the form of reports.

Technical and economic:

1) “all in one” – all components of DUV 2/0.005-10 are assembled into one unit/casing, do not require any additional modules and adjustments, i.e. it is an out-of-the-box universal tool to execute monitoring of water reserves irrespective of the availability of power supply and other technical and weather conditions.  The simple Sensor’s design facilitates installation and start-up and commissioning, as well as allows minimizing labor costs;

2) DUV 2/0.005-10 is flexible in terms of installation, data transfer methods, measurement subject (water level or hydro-lock position, etc.);

3) the cost of the measuring unit is 3-4 times less compared to currently available alternatives;

4) DUV 2/0.005-10 designed architecture allows increasing the number of controlled points and performing an integrated monitoring of the whole network.

Уроки:

Достоинства импульсного дождевания подтверждаются исследованиями, проведенными на других опытных участках КазНИИВХ в Жамбылской области, которые позволили повысить биологическую урожайность яблонь сорта «Голден Делишес» на 10,1-36,8 %, товарную – на 16,6-49,4 % по сравнению с поливом обычным дождеванием.

Рекомендации:

Нужно продолжать применение таких практик на предгорных местностях в Центральной Азии, где есть проблема с энергоснабжением.

Lessons learnt:

Deployment of the DUV 2/0.005-10 Water Level Sensor led to increased precision of water level and consumption measurements and higher promptness of information collection compared to any known methods.

Using the device in the conditions of water resources deficiency, on the one hand, will ensure objective accounting of water use and, on the other hand, will promote water conservation among water users which will lead to more efficient technological development of agro-industrial complex and higher labor productivity.

Recommendations:

The success of deploying water level sensors in project hydro-posts facilitated execution of measures to disseminate the positive experience of using the device in the water sector.  Their effect will be even more significant as enhanced quantity and quality indicators will ensure effective management of water resources and water conservation with simultaneous development of irrigated agriculture.
