摘　　要：文章系统总结了西藏肥料使用中的问题:化肥用量整体偏低;秸秆还田和有机肥投入严重不足;肥料施用不科学、不均衡,利用率不高;土壤供肥能力弱;科学施肥基础薄弱。并在此基础上,提出了西藏科学施肥的建议:制定合理的发展战略;提高科学施肥水平;科学发展有机肥;发展养分资源综合管理技术,统筹增产、提质、增效;夯实科学施肥基础。The paper systematically summarized the problems about fertilizer application in Tibet:The amount of chemical fertilizer consumption is low;The straw return and organic fertilizer input is seriously insufficient;The fertilizer application is unscientific and unbalanced,and the utilization rate is not high;The soil fertilizer supply capacity is weak;The foundation of scientific fertilization is weak. On this basis,we put forward suggestions on scientific fertilization in Tibet:Formulate reasonable development strategies;Improve the level of scientific fertilization;Develop organic fertilizer scientifically;Develop comprehensive management technology of nutrient resources,coordinate to increase production,improve quality and high efficiency;Consolidate the foundation of scientific fertilization.
