Description

Изобретение относитс к сельскому хоз йству и может быть использовано дл определени сроков и норм полива.The invention relates to agriculture and can be used to determine the timing and rate of irrigation.
Известен способ определени срока полива путем замера испарени с открытой испар ющей поверхности реализуемый при помощи устройства, состо щего из сосуда снабженного пористым испарителем с регулируемой испар ющей поверхностью СП .A known method for determining the irrigation time by measuring evaporation from an open evaporating surface is realized using a device consisting of a vessel equipped with a porous evaporator with an adjustable evaporation surface SP.
Недостатком известного способа вл етс снижение точности замеров во времени за счет зарастани пористого испарител микроводоросл ми.The disadvantage of this method is the reduction in the accuracy of measurements in time due to the overgrowth of the porous evaporator with microalgae.
Цель изобретени - повышение точности определени сроков и норм полива, а также имитации водопотреблени сельскохоз йственными культурами .The purpose of the invention is to improve the accuracy of determining the timing and norms of irrigation, as well as imitation of water consumption by agricultural crops.
Указанна цель достигаетс тем, что регулируют площадь открытой испар ющей водной поверхности посредством сменных поплавков, площадь которых соответствует биоклиматическим коэффициентам растений.This goal is achieved by regulating the area of the open evaporating water surface by means of interchangeable floats, the area of which corresponds to the bioclimatic coefficients of plants.
На чертеже представлено устройство дл определени сроков и норм полива .The drawing shows a device for determining the timing and rate of irrigation.
Устройство имеет сосуд 1, наполн емый водой, с переливным отверс- . тием 2, сменный поплавок 3. шкапу , ограничитель осадков 5 и кожух 6 с гнездом дл сосуда.The device has a vessel 1 filled with water, with an overflow opening. tiyom 2, replaceable float 3. cabinet, precipitation limiter 5 and casing 6 with a nest for the vessel.
Способ осуществл ют следующим образом.The method is carried out as follows.
В начальный момент, т.е. весной сосуд устройства заполн ют водой до нулевой отметки на шкале. В соответ15 ствии с биохимическим коэффициентом поливаемой сельскохоз йственной культуры на данном периоде вегетации, определ емым опытным путем, в сосуд опускаетс сменный поплавок. По ме20 ре испарени уровень, воды в сосуде . снижаетс . Срок полива определ етс снижением уровн до критической отметки нашкале, соответствующей нижAt the initial moment, i.e. In the spring, the vessel of the device is filled with water to zero on the scale. In accordance with the biochemical coefficient of the irrigated agricultural crop at a given vegetation period, determined experimentally, a replaceable float is lowered into the vessel. According to the evaporation level, the water in the vessel. decreases. The irrigation period is determined by lowering the level to a critical point on the scale corresponding to the lower
