摘　　要：采用问卷调查方法对广东省惠东县30户典型种植户的冬作马铃薯施肥状况进行调查分析。结果表明:广东省惠东县冬作马铃薯化肥氮(N)、磷(P2O5)、钾(K2O)平均每667 m2施用量分别为16.33、18.94、20.32 kg,化肥施用量N∶P2O5∶K2O=1∶1.16∶1.24;有机肥氮(N)、磷(P2O5)、钾(K2O)均値与化肥氮(N)、磷(P2O5)、钾(K2O)均値之比分别为0.36、0.28、0.26;采用"基肥(化肥)+3次追肥"和"基肥(化肥)+2次追肥"施肥模式的户数分别占调查总户数的46.67%和40.00%,是惠东县的主要基追模式。The fertilization status of winter potato with thirty typical planters in Huidong county of Guangdong province was investigated and analyzed through using questionnaire-investigation method. The results showed that every 667 m2 chemical fertilizer N, P2O5, K2O average application rates of winter potato in Huidong county, Guangdong province were 16.33,18.94,20.32 kg with the typical planters,respectively, and chemical ferilizer N：P2O5：K2O=1：1.16：1.24; The ratios of average N, P2O5, K2O rates from organic manures to those from chemical fertilizers were 0.36, 0.28 and 0.26, respectively. The planters with fertilization patterns of ＂base fertilizer （chemical fertilizer） ＋ three-time top dressing＂ and ＂base fertilizer （chemical fertilizer） ＋ two-time top dressing＂ respectively accounted for 46.67% and 40.00% of total planters under investigation, which were the main base fertilizer-top dressing fertilization patterns.
