摘 要:根据土壤普查,施肥研究和调查资料以及有关统计数据,对兵团施肥现状及存在问题进行分析,并对兵团施肥状况进行评价。目前,施肥和肥料结构不合理,肥料分配不当,浪费严重,并且引起环境污染,科学施肥到位率低等是兵团现阶段施肥存在的主要问题。科学施肥,重视有机肥的应用,提高化肥利用率,减少肥料对环境的污染将是今后施肥工作的主要任务。Data of soil survey,field experiments and sampling investigation were adapted to reveal cruent fertilization states,issues needing to be improved in Xinjiang Production and Consturction Corps are discussed in the paper, and fertilization level is discussed as well. Results indicated that unreasonable fertilizer structure, uneven fertilizer distribution, waste of fertilizer, environment pollution and bachkard in fertilixation technique are the main obstacle in scientifical appl ication of fertilizer. In order to promote fertilization quality, reasonable fertilization, to rise chemical utilization ration and reduce environment pollution is the matter of the utmost concern in the future in Xinjiang Production and Consturction Corps.
