Summary |
Study
of alfalfa high yield obtaining possibility in rice rotation
maintaining soil-reclamation state of irrigated lands; creation
of optimal conditions for main crop-rice; irrigation regime
and measures on prevention of seasonal salt restoration
in root zone development; soil fertility increase; ground
water dynamics management and revealing possibility for
its contribution to sub-irrigation. Kyzylkum massif is located
on flat plain, soils are meadow-serozem, climate is continental.
Soils consist of two layers: top-3m thick made of sandy
loam and bottom-60v thick made of sand. Ground water is
saline; irrigated area is 40ha; rice system is of Krasnodar type; irrigation canals of twofold action. In result of investigations
economically expedient irrigation regime of alfalfa is
recommended providing 9.26-10.44t/ha. Irrigation norm and
schedule are determined. Amendments to designed irrigation
norm under flood, furrow and sprinkler irrigation. |
