Abstract

Two groups of yield response functions of cotton in Tarim Basin are established according to the salt tolerance data from three experimental sites,which are based upon linear and non-linear by spss for Windows.One is a group of linear response functions which contain two independent parameters: the salinity threshold(st) and the slope(c) of the curve.The other is a group of non-linear shaped curve response functions which contain two independent parameters: s50(the salinity at which the yield is reduced by 50%) and(an empirical constant).The non-linear functions and their thresholds of salt tolerance can correspond with the cotton yield-soil salinity in Tarim Basin better than the linear response functions by analyzing their differences.
