Experience on fixing mobile sands in the Aralkum village
AbstractThe article presents the results of measures on fixation of moving sands by phytomelioration methods in combination with the establishment of mechanical protection against blowing in the area of 2hectares that divided into two plots by livestock drive track around which metal fences were installed.Species of local flora were used for phytomelioration: Haloxylon ammodendron (saxaul), Calligonumspp, Artaphaxis spinosa, Krascheninnikovia ceratoides (eurotia), Kochia prostrata. Results on monitoring of plantation in the first growing season showed that survival rate of saplings varied depending onthe geomorphological conditions of the plots from 32 to 60 % for saxaul and 24-40 % for calligonum.Atraphaxis did not take root. The survival rate for saxaul seedlings was 22 %, for eurotia – 9%, for kochia– 17%. Monitoring of plantings in the third year of the survey showed that 35 to 53% of saxaul saplings,24-36% of calligonum saplings, 59% of eurotia seedlings, 16% of saxaul seedlings, less than 5% of kochia seedlings were survived in the plantation. Young growths of calligonum appeared in the third yearafter sowing, self-sowing of eurotia began in the third year. One of the plots is regularly disturbed bylivestock, which leads to degradation of plantations, a reduction of seed germination and a decrease insand-strengthening function. Based on the experience gained, recommendations have been developedthat can be used to establishment of new sites in the Aralkum village and for phytoreclamation in otherareas of mobile sands in the Aral region.Key words: Aralkum, phytomelioration, desert plants, saxaul, survival rate.
