Изобретение относитс  к сельскому хоз йству , в частности к мелиорации, и может быть использовано дл  орошени  риса с одновременным удобрением его.The invention relates to agriculture, in particular to amelioration, and can be used to irrigate rice while at the same time fertilizing it.

Известен способ орошени  риса с одновременным внесением удобрений, включающий, подачу в чек сосредоточенным током поливной воды с растворенными в ней удобрени ми и создание в нем сло  воды.There is a known method of irrigating rice with simultaneous application of fertilizers, which includes feeding the check with a concentrated current of irrigation water with fertilizers dissolved in it and creating a layer of water in it.

Однако по известному способу больша  часть растворенных в воде питательных вешеств поглош:аетс  почвой в самом начале тока воды (у водовыпускного сооружени ). На остальные участки чека поступает обедненна  питательными веществами вода, что приводит к крайне неравномерному распределению удобрений по полю, а следовательно, и к неравномерному развитию и созреванию посевов риса или другой культуры, сопутствующей рисовому севообороту.However, according to a known method, most of the nutrient substances dissolved in water are absorbed: the soil is at the very beginning of the water flow (at the water outlet). The remaining parts of the check receive nutrient-depleted water, which leads to an extremely uneven distribution of fertilizers throughout the field, and consequently, to the uneven development and maturation of rice crops or other crops associated with rice crop rotation.

Цель изобретени  - равномерное распределение удобрений по площади затоплени .The purpose of the invention is the uniform distribution of fertilizers over the flooded area.

Достигаетс  это тем, что в чеке до подачи воды с растворенными удобрени ми почву в нем увлажн ют до полного влагонасыщени .This is achieved by the fact that in the check, before the water is supplied with the dissolved fertilizers, the soil in it is moistened to full moisture saturation.

После посева сем н риса в сухую почву поле заливают слоем воды 1-2 см, после чего подачу воды прекращают до полного впитывани  созданного сло . При этом почва доходит до состо ни  полного насыщени . ДалееAfter sowing rice seeds in a dry soil, the field is poured with a layer of water 1-2 cm, after which the water supply is stopped until the created layer is completely absorbed. At the same time, the soil reaches a state of complete saturation. Further

к оросительной воде у мест ее сосредоточенного отбора (например, у водовыпусков), добавл ют концентрированные растворы питательных веществ. Содержание их в оросительной воде довод т до 0,3-0,6%. Поливную воду с растворенными в ней веществами сосредоточенными расходами (7-10 л/сек на 1 га) подают в чек, где снова создают слой воды 1-2 см, который, насыща  верхние слои почвы , создает необходимый питательный режим в зоне развити  корневой системы растений. С дальнейщим развитием растений в зависимости от фазы вегетации в чеке создают слой воды 5-15 см. При необходимости внесени to the irrigation water at the places of its concentrated selection (for example, at water outlets), concentrated solutions of nutrients are added. Their content in irrigation water is adjusted to 0.3-0.6%. Irrigation water with dissolved substances dissolved in it (7-10 l / s per 1 ha) is fed into a check, where a 1-2 cm water layer is again created, which, filling the upper soil layers, creates the necessary nutrient regime in the zone of root development plants. With the further development of plants, depending on the vegetation phase, a layer of water of 5-15 cm is created in the check.

питательных веществ в этот период подача воды прекращаетс  до полного срабатывани  сло  на испарение, транспирацию и фильтрацию . Однако почва должна быть насыщена до полной влагоемкости. Подача в чек оросительной воды с растворенными в ней удобрени ми осуществл етс  как н в предыдущем случае, после чего предыдущий слой воды в чеке восстанавливают.nutrients during this period the water supply is stopped until the layer fully operates on evaporation, transpiration and filtration. However, the soil must be saturated to full capacity. The irrigation water with fertilizer dissolved in it is fed into it as in the previous case, after which the previous water layer in the check is restored.
