FIELD: agriculture.
SUBSTANCE: method of crop irrigation in rice crop rotation comprises formation on the surface of the check of the ridge surface and the furrows, laying of drainage elements, planting upland rice or other crops of rice crop rotation, supply into the furrow of irrigation water and drainage loss. The novelty of the invention is that prior to the formation of ridges and furrows the chemical ameliorant is applied on the surface of the check, improving the properties of alkaline soils, and along the central part of the ridges parallel to furrows at a depth of 0.5-0.7 m mole drains are laid.
EFFECT: significant reduction in intensity of salt accumulation in the ridge part of the furrows, elimination of risk of secondary salinisation and alkalinisation, improvement of soil structure and providing sustainable draining effect.
