Abstract: The integrated premature and frost-avoiding cultivation techniques of cotton were studied．The results show that by spraying zhuangzaofeng in cotton growing stage，the boll numhers per plant and bo ll weight increase，the boll open-ing period is 2～ 4 days early，the lint yield increases by 12.23％ compared with the control，and the cotton fiber characters have not been affected obviously．The system of integrated early mature cultivation techniques(SIPCT)including spraying zhuangzaofeng，increasing the plant densities ，optium sowing date，mulching with plastic film，selecting earlier varieties，ra．tional fertilizer application and water irrigation，complex preventing from pest and diseases ，spraying ethrel for late mature tO avoid frost damage is put forward，the lint yield increases by 14.34％ ～24.58％ compared with the contro1．
