Selection of perspective phytomeliorants improvement of saltwort pastures of Kyzylkum desert

Kyzylkum amongst central Asiatic deserts is one of the largest a really and to economic meaningfulness. Besides typical sandy education to this desert peculiar and such depression, as Ayakagytma, Karagat, Mingbulak, Beshbulak and others. Specified pasture lands on its fertility low productive, him inherent such line as sharp continental climate, complexity, complexity subzero forage to the productivity, sharp fluctuations to productivity, to the food value of value of forage on years and by the season of year. 87 standards of halophytes are tested by related to 35 botanical families. Amongst them perspective phytomeliorantes for the improvement of pastures Kyzylkum from a number eutherophytes appeared - Climacoptera lanata (Pall.), Atriplex nitens, Kochia scoparia, Bassia hyssopifoliа (Pall.) O. Kuntze. To the number of perspective of long-term halophytes belongs Haloxylon aphyllum (Minkw.) Ilin., Halothanus subaphyllus (C. A. Mey.) Botsch., Salsola orientalis S. G. Gmel., Artemisia halophilla Krasch, Aeleropus litoralis and others. Research such agrotechnical receptions as terms of sowing, norms of sowing of seed and different depths of sealing-off of seed of perspective halophytes. Most factor field germinating ability of seed noted beside Climacoptera lanata (Pall.) under December and March period of the sowing. The similar picture is fixed and on sowing Atriplex nitens, survival of seedlings at sowing at different periods are fixed at sowing at February then under later period of the sowing harvest stern mass noticeably it falls. Sealing-off seeds Climacoptera lanata (Pall.) and Atriplex nitens on depth 1-2 refer to raises their germination ground of seeds 30,6-53,6%; on measure of the deepening the sealing-off seeds reduction germination ground of seeds exists beside both type halophytes.
