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。
在廣東省肇慶市農業科學研究所試驗基地開展豇豆＂3414＂肥效試驗,結果錶明：在氮、燐、鉀養分三要素中,氮素素是豇豆產量的第一限製因子,鉀素是第二限製因子,燐素是第三限製因子;在14箇施肥水平處理中,施肥效果最佳的是組閤N2P1K1,即純氮、五氧化二燐、氧化鉀理論最佳施肥量分彆為6.00、4.50、5.75 kg/667 m2,純氮∶五氧化二燐∶氧化鉀為1.00∶0.75∶0.97。
