Title: Necessity and Feasibility of Biotic Improving the Saline and Alkaline Land in Xinjiang
Abstract: Utilizing the resource of saline and alkaline land, ameliorating the salinization cropland, are the important link of the developing agricultural production ,in regions of saline and alkaline land. The area of the saline and alkaline land in Xinjiang which have 21 814 thousand hectare, is 22.01% by comparison with the total area of saline and alkaline land of the whole country. The area that have being imperiled in different degree by salinization take 30.12%, in 4 078.4 thousand hectare of the cropland in Xinjiang. Biotic reclamation of the saline and alkaline land means the direct planting of the salt- enduring plant in salinization land, in conventional irrigation, not to require any subsidiary condition and facilities,in which the soil salinity is retained beyond the root system zone in soil profile. The plant produce of the flooding form is in favor of this kind ameliorative mode in Xinjiang. Biotic amelioration mode, the irrigative water is high utilized by plants,in favor of the favorable circulation and perpetual build of the ecological environment system. When the salt-enduring plant of the more root system and the deep root system is planted,the salinity move down deep in soil profile,with the irrigation.
