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。

摘  要:
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.
