摘    要:在广东省肇庆市农业科学研究所试验基地开展豇豆"3414"肥效试验,结果表明:在氮、磷、钾养分三要素中,氮素素是豇豆产量的第一限制因子,钾素是第二限制因子,磷素是第三限制因子;在14个施肥水平处理中,施肥效果最佳的是组合N2P1K1,即纯氮、五氧化二磷、氧化钾理论最佳施肥量分别为6.00、4.50、5.75 kg/667 m2,纯氮∶五氧化二磷∶氧化钾为1.00∶0.75∶0.97。

Abstract:Experiment of '3414' soil testing and formulated fertilization for cowpea was conducted in experimental base of Zhaoqing Agricultural Science Research Institute of Guangdong Province.The results showed that:among the three factors,N was the first restricting factor,K2O was the second restricting factor,P2O5 was the third restricting factor;among the fourteen treatments of fertilization level,N2P1K1 reached the best yield effect,the best applying amounts of N,P2O5,and K2O were 6.00,4.50,5.75 kg/667 m2 respectively,and the ratio of them was 1.00∶0.75∶0.97.
Keywords:cowpea  fertilizer formua on soil-detective  effect  Zhaoqing Guangdong
