FIELD: agriculture. ^ SUBSTANCE: invention relates to the field of agriculture and land reclamation. The method includes discharge and drainage outflow of seepage water, application of nitrogen fertilisers and herbicides, transferring of map and site drainage and discharge channels to the mode of backwater and return the water through a water lift. Thereat the air-heating installation is mounted at the site of conjugation of the site drainage and discharge channel and the intra-entity collector, and is used for energy conversion of the hydraulic drop in the air pressure, which is reported to the water lift to return the water. ^ EFFECT: method enables to reduce the number of hydro-mechanical devices per area unit of rice irrigation system, to increase the use of drainage and discharge runoff, to improve the conditions of mixing and dilution with water from the waste ditch with clean irrigation water, along with an increase in fertiliser use efficiency for rice growing. ^ 2 dwg |
