RICE DRYING-HUMIDIFYING SYSTEM Russian patent published in 2024 - IPC A01G22/22 A01G25/00 

FIELD: agriculture.

SUBSTANCE: rice drainage and humidification system comprises rice paddies, a distribution pipeline, distribution wells, a discharge collector, irrigation pipelines combined with drainage and discharge pipelines, water outlet structures combined with discharge structures. The system additionally has closed field irrigation discharges, moistening drains with a diameter of 50 mm and an outflow of 10 l/h per 1 linear m, which are located parallel at a distance of 0.7 m from each other, a crop rotation distributor, an area discharge, the last order distributor, and filter geotextile. Moistening drains are connected perpendicular to the closed field irrigation discharge, located to it with a slope of 0.0003 to a depth of 0.05 m. Perpendicular to the local discharge and the last-order distributor, a closed field irrigation discharge is connected through distribution wells, which is laid with a slope of 0.003 to the local discharge to a depth of 1 m and with a diameter of 560 mm.

EFFECT: saving irrigation water, reducing operational work, improving the reclamation state of rice soils and increasing rice yield by increasing the coefficient of land use, using resource-saving technologies for rice cultivation and creating a favourable water-air conditions in the root layer of the soil, increasing the environmental safety of rice irrigation systems through reducing volumes of pollutants removed from the rice irrigation system through drainage and discharge waters into the receiving water.
