摘 要:分析了我国化肥区域间和淡旺季供需情况与价格变化。统计资料及调查数据表明,近年来我国氮肥、磷肥产能过剩,钾肥自给率提高;春耕、夏播、秋冬种氮肥、磷肥供应充足,钾肥缺口较大;空间分布方面,河南省化肥缺口达约240万t,广西、黑龙江、吉林省缺口约160万t;化肥零售价格年度间和同年度不同季节间波动较大,加剧了地区和季节间供需矛盾。建议国家进一步遏制产能过剩,加强区域调度,抑制价格波动,推广科学施肥技术。The fertilizer supply and application at the national scale, provincial scale and seasonal level are analyzed. Based on the statistical data and survey data, in recent years, the capacity of nitrogen fertilizer and phosphate fertilizer is overcapacity, potassium fertilizer self-sufficient rate is increased gradually in China; In spring, summer, autumn and winter, the supply of N, P205 is surplus, but K20 is deficient. In provincial scale, the fertilizer (N, P205, K20) deficiency reaches 2.40 million tons in Henan province, about 1.60 million tons in Guangxi, Heilongjiang, Jilin; The fertilizer price fluctuated strongly between years and seasons, which intensifies the contradiction of fertilizer supply and demand indifferent region and season. The government should control overcapacity, strengthen regional supplying balance, extend scientific fertilization technology.
