Resources saving technique of water regulation of soils on reclamative systems of polder type

Abstract

Purpose. To develop a resource-saving technology for regulating the water regime of soils in polder type land reclamation systems. Methods. Analytical and theoretical with application of mathematical modeling, experimental methods of researches on production sites of reclamation systems. Results For realizatsiyiresursooschadnoyi technology water regime on production sites polder system "Ikva" volohozabezpechenist perennial grasses increased by 15- 20%. In modules plot of 245 hectares of saving water - 48.7 thousand. M3 per year of electricity consumed - 45.7 kW / h per 1 ha drainage, which is 5.7% per year, without reducing the average yield of perennial grasses. Conclusions Saving water and electricity expenses achieved through the introduction of resource-saving technological parameters of water regime and purposeful creation akumulyuvalnyh capacities in the root layer of soil.
