[目的]为探讨中山市苦瓜最高施肥量与产量、最佳施肥量与产量的关系,达到节肥增产优质、高效、环保目的。[方法]开展测土配方施肥“3414”田间肥效试验。[结果]中山市苦瓜最佳施肥配方为施N 262.5 kg/hm2、P2O576.5 kg/hm2、K2O 157.5 kg/hm2,得出最佳施肥配比为1.00∶0.29∶0.58。[结论]该研究可以为科学地进行苦瓜测土配方施肥提供参考。
[Objective] The purpose was to discuss the relationship between the highest fertilization amount and the yield, the best fertilization amount and the yield of bitter gourd in Zhongshan City, so as to achieve the purpose of high yield, high efficiency and environmental protection by yield and fertilizer. [Method] Carrying out soil fertilization test “3414” in field. [Result] The optimal fertilization formula of bitter gourd in Zhongshan was N 262.5 kg / hm2, P2O576.5 kg / hm2 and K2O 157.5 kg / hm2, and the best fertilization ratio was 1.00: 0.29: 0.58. [Conclusion] This study can provide scientific reference for the fertilization of bitter gourd by soil testing.
