摘要： 为了探讨氮磷钾肥料配施对甜瓜主要经济性状的影响，采用3因素5水平2次正交旋转组合设计，研究N、P、K配施对甜瓜产量的影响，构建肥料配施的数学模型，并对最优施肥量、单因子效应及互作效应进行分析。结果表明：N与P、N与K、P与K之间存在明显的互作效应，且适宜的施肥配比可以提高甜瓜的产量；当N、P、K配比为2.03:1:3.36，即氮(N)、磷(P2O5)、钾(K2O)用量分别为157.5、77.4、260.38 kg/hm2时，甜瓜的最高产量可达51893.205 kg/hm2。

Abstract: For research the effect of the economic traits of melon by nitrogen, phosphorus and potassium balanced fertilization, by means of quadratic component rotational design, the effect of N, P and K balanced fertilization on the yield of cucumber was studied in article. The mathematic model of balanced fertilizers was established. The optimal quantity of fertilizer, the effect of single factor and the interaction effect were studied. The results showed that between N and P, between N and K, between P and K had significant interacting effects, and the right fertilization ratio could improve the production of melon. The ratio of N:P:K were 2.03:1:3.36, and the amount of N, P2O5 and K2O respectively were 157.5, 77.4, 260.38 kg/hm2, and the highest yield of melon was 51893.205 kg/hm2.
