临泽草地生态试验站的本底研究

对拥有２８０ｈｍ＾２盐渍化草地的临泽划地生态试验的基本研究表明，土壤盐分含量３．６ｇ／１００ｇ于土左右，属硫酸盐为主的盐渍化土壤。植被以盐生植物为主体，芦苇、赖草、碱蓬、盐爪爪等为优势种。将植被与盐渍土壤质地叠加，形成反映初始状况的综合生态图。试验区内的地下水位高，水南矿化度较大。培育后的盐渍草甸草的初级生产明显提高，但草地的蛋白质生产能力不佳，有待引入抗盐豆科牧草。

THE BASE RESEARCH OF LINZE GRASSLAND ECOLOGICAL TEST STATION

The basic research on Linze Grassland Ecological Test Station owning 280 hm 2 salinity grassland showed that contents of salt in soil were about 3.6 g per 100 g dry soil, it was salinity soil which was mainly sulphate salt. Vegetation was main halophyte Phragmtes communis, Aneurolepi dasystachys, Suaeda splendens, Kalidium gracile were dominant. Folding vegetation and salinity soil could form to reflect a comprehensive map of initial state. The underground water level in test area was high and big in mineralized intensity. The premary productivity of salinity meadow grassland after improving was obviously increased, but the ability of producing protein in grassland was not good, the salt-resistant leguminous grasses should be introduced.
