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。
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.
