摘　　要：以广东省恩平市主栽马铃薯品种之一祚实1号原种合格脱毒种薯为材料,采用随机区组设计,研究有机无机复混肥对马铃薯产量和品质的影响,旨在为该地区马铃薯生产中合理施用有机无机复混肥提供理论依据。结果表明,T_3处理具有显著的增产效益,可保障马铃薯块茎品质,商品薯率最高,经济效益亦最高;且该处理偏生产力(119.85 kg/kg)和农学效率(67.10 kg/kg)均为最高。综合考虑马铃薯产量、品质、肥料利用率及经济效益,推荐在冬作马铃薯生产中,施用900 kg/hm^(2)有机无机复混肥料作为适宜的施肥方案。Using Zuoshi No.1,one of the main potato varieties cultivated in Enping City,Guangdong Province,as the material,a randomized block design was used to study the effects of organic-inorganic compound fertilizer on potato yield,quality,etc.The aim was to provide theoretical basis for the rational use of organic-inorganic compound fertilizer in winter potato production in this area.The results showed that T 3 treatment had significant yield increasing benefits,could ensure the quality of potato tubers,had the highest commercial potato rate,and the highest economic benefits;and the partial productivity(119.84 kg/kg)and agronomic efficiency(67.10 kg/kg)of this treatment were both the highest.Taking into account potato yield,quality,fertilizer utilization rate,and economic benefits,it is recommended that 900 kg/hm^(2) of organic-inorganic compound fertilizer be applied as a suitable fertilization scheme for winter potato production.
