安徽马铃薯肥料利用现状调查

Investigation on Fertilizer Utilization Status of Potato in Anhui

[目的]掌握安徽马铃薯生产基本信息和肥料施用情况,为化学肥料减施增效利用研究与示范推广提供基础数据。[方法]对安徽界首、阜南、临泉、蒙城、怀远、舒城等市(县)典型种植户的马铃薯栽培模式、施肥数量、施肥类型和方法、产量等进行统计,研究肥料利用率和贡献率。[结果]安徽6个马铃薯产区氮肥利用率为22.95%~33.19%,磷肥利用率为6.34%~13.24%,钾肥利用率为40.88%~67.12%,肥料贡献率为58.81%~63.03%。[结论]针对安徽马铃薯生产中在肥料管理方面存在的问题,提出化学肥料减施增效利用对策。

[Objective]To grasp the basic information of potato production and the general situation of fertilizer application in Anhui Province, and provide the basic data for the research and demonstration of chemical fertilizer utilization.[Method]The potato cultivation mode, fertilizer quantity, fertilizer type and method, yield of typical farmers in Anhui Jieshou, Funan, Linquan, Mengcheng, Huaiyuan, Shucheng and other cities (counties) were counted, and the fertilizer utilization rate and contribution rate were studied.[Result]The nitrogen utilization rate was 22.95%-33.19%, the phosphorus utilization rate was 6.34%- 13.24%, the potassium utilization rate was 40.88%- 67.12%, and the fertilizer contribution rate was 58.81%-63.03%.[Conclusion]Aiming at the problems of fertilizer management in potato production in Anhui Province, the countermeasures of reducing fertilizer use and increasing efficiency were put forward.
