Maqolada sprinkler sug‘orish tizimi samaradorligini baholash va ishonchli loyihalash uchun ayrim dala tadqiqotlarini bajarish usullari yoritilgan. Shuningdek, sug‘orish tizimida suv sarfining hudud bo‘ylab taqsimlanishi va undagi yo‘qotishlar tahlil qilinadi. Sprinklerning suv taqsimotini baholashda Kristiansenning Cu o‘xshashlik koeffitsiyentidan foydalanildi. Catch Can usuli uch turdagi kombinatsiya: sprinkler balandligi, sprinklerdan chiqayotgan suv sarfi va napor o‘zgarishini o‘rganish orqali amalga oshirildi. Kristiansen koeffitsiyenti bir necha xil naporda sprinkler balandligiga ko‘ra sarfning taqsimlanishini hisobga olishdagi tajribalar yig‘indisi asosida aniqlandi. Tadqiqotlar Farg‘ona viloyatining O‘zbekiston tumani “XXI asr xirmoni” fermer xo‘jaligida olib borildi. Yuqorida keltirilgan usul asosida suv taqsimotini baholashda eng maqbul balandlik aniqlandi. Dala tajribalari hamda ularning tahlili asosida suv sarfi bo‘yicha sprinkler balandligi va oqim taqsimoti asosida grafik tuzildi.

В статье описаны методы проведения некоторых полевых исследований для оценки эффективности систем орошения дождеванием и их надежного проектирования. Также анализируется распределение водопотребления по территории оросительной системы и ее потери. Коэффициент распределения Кристиансена Cu используется для оценки распределения воды спринклера. Он расчитывался путем изучения трех типов комбинаций по методу Catch Can, т. е. высоты оросителя, расхода воды оросителя и изменения давления. Для определения коэффициента Кристиансена его рассчитывают по сумме опытов с учетом распределения расхода по высоте оросителя при нескольких различных значениях давления. Исследования проводились в фермерском хозяйстве «XXI asr xirmoni» Узбекского района Ферганской области. На основе приведенного метода была определена оптимальная высота при оценке водораспределения. На основе полевых экспериментов и их анализа был построен график, основанный на высоте оросителя и распределении расхода воды.
The article describes the methods of some field studies to assess the efficiency of sprinkler irrigation systems and their reliable design. The distribution of water consumption over the irrigation system area and its losses are also analyzed. The Christiansen distribution coefficient Cu is used to estimate sprinkler water distribution. It was calculated by examining three types of combinations using the Catch Can method, that is, sprinkler height, sprinkler water flow, and pressure variation. To determine the Christiansen factor, it is calculated from the sum of the experiments, taking into account the distribution of flow over the height of the fill at several different pressures. The research was conducted on the farm “XXI asr xirmoni” of the Uzbek district of Fergana region. Based on the given method, the optimum height was determined when estimating the water distribution. Based on the field experiments and their analysis, a graph based on the irrigator height and flow distribution was plotted.
