Целью работы явилась разработка технических средств и устройств на широкозахватные дождевальные машины для прецизионного орошения сельскохозяйственных культур, обеспечивающих соответствие объема воды требуемому уровню влагозапасов участков поля на момент их полива, а также оценка перспективности применения технологии. В статье рассмотрены возможности модернизации широкозахватной дождевальной машины, вариант с блочным управлением дождевателями по учащенной схеме и непосредственное управление дождевателем через индивидуальный электромагнитный клапан. Регулируемая подача воды осуществлялась с помощью программируемого логического управления и электромагнитных клапанов. Даны стратегия точного орошения и применяемые технические средства. Рассмотрены характеристики работы машин – в частности, изменение слоя осадков в зависимости от режима полива; зависимость между рабочим давлением и изменением расхода дождевателей. Дана оценка коэффициента эффективности полива Кристиансена при различных режимах полива. Сделаны выводы об эффективности и целесообразности применения технологии прецизионного орошения и даны рекомендации.</p></abstract><trans-abstract xml:lang="en"><p>The precision irrigation system is a technology that allows you to supply a metered volume of water directly to the required area of the field, reducing resource costs, providing economically sound and environmentally safe irrigation. The purpose of the work was to develop technical means and devices for wide-range sprinklers for precision irrigation of agricultural crops, ensuring that the volume of water corresponds to the required level of moisture reserves of field areas at the time of their irrigation, and to assess the prospects for using the technology. The article discusses the possibilities of upgrading a wide-range sprinkler machine. A variant with block control of sprinklers according to the accelerated scheme and direct control of the sprinkler through an individual solenoid valve. The regulated water supply was carried out using programmable logic control and electromagnetic valves. The strategy of precision irrigation and the technical means used are given. The characteristics of the machines are considered. In particular, the change in the precipitation layer depending on the irrigation regime. Relationship between operating pressure and change in sprinkler flow. The Christiansen irrigation efficiency coefficient under different irrigation regimes is estimated. Conclusions are made about the effectiveness and expediency of using precision irrigation technology and recommendations are given.
