| 摘 要： | 以津优Ⅰ号黄瓜为试验作物，采用“3414”完全随机区组试验方案，开展黄瓜氮磷钾肥料效应研究。结果表明：试验条件下可采用三元二次方程拟合来预测产量；施肥对黄瓜增产具有极显著的效应，增产效果最好的是钾肥、其次是氮肥、最后是磷肥；在中高肥力条件下，海南栽培黄瓜应以施N 226.5 kg/hm2、P2O557 kg/hm2、K2O 244.5 kg/hm2较为适宜，其N：P2O5：K2O=4.0：1：4.3。

| Abstract: | Taking cucumber variety Jinyou No.1 as experimental material, and using ＆quot;3414＆quot; random complete block dsign method to study the efficiency of nitrogen （N）, phosphorus （P） and potassium （K） fertilizers to cucumber. The results showed that under the experimantal conditions, it can use fitting of quadratic equation with three factors to predict cucumber yield; fertilization had extremely significant yield-increasing effect to cucumber, among which the K fertilizer had the best yield-increasing effect, the N fertilizer followed, and the P fertilizer was the worst. With the medium and high fertility, the optimal fertilizer rate of N, P and K for planting cucumber in Hainan province was 226.5 kg/hm2, 57 kg/hm2 and 244.5 kg/hm2, respectively, and the N：P2O5：K2O=4.0：1：4.3. |
