摘　　要：研究表明 ,在南疆兵团植棉农场 ,现行施肥水平已能满足棉花实现超高产对大量元素的需求 ,限制产量提高的因子不再是施肥量 ,应从微量元素施用、改善施肥方法及提高精细栽培水平方面入手。一般肥力水平的条田有实现高产的可能 ,但若要持续高产、稳产 ,必须培肥地力。Through preliminary study,it is suggested that on Division 3 cotton farms in the South of Xinjiang,the present applying fertilizer can meet the needs of cotton for superhigh yield.Increasing cotton yield no longer relates to the amount of fertilizer,but to trace element,improving the method of applying fertilizer and advanced cultivation techniques. The avarage fertilizer can make cotton be high yield crop.In order to keep up a steady increase in high and stable yields of cotton,it is necessary to improve the soil fertility,inctease and keep high basic fertility of oil
