【 摘 要 】

Results of researches of water and salt modes of alluvial soil of Mesopotamic plain are stated at a spring wheat irrigation. It is established that the favorable water mode of soil is created at average irrigating norm of 5420 m3/hectare, 856 m3/hectares, and total водопотреблении7133 m3/hectare. Predecessors made small impact on preservation of productive moisture only during the the preseeding and harvest periods. Role of predecessors and nitric fertilizers on accumulation of salts in the soil is slight, the soil remained slightly salted. Process of carrying out of salts is marked during the winter period, and their seasonal accumulation of salts during the warm period of year which are mutually compensated.
