摘要： 为分析氮磷钾肥料配施对甜瓜Vc的影响，通过采用3因素5水平二次正交旋转组合设计，研究N、P、K配施对甜瓜果实中Vc含量的影响，构建了肥料配施的数学模型，并对最佳施肥量、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果实中Vc的含量。分析认为，当N、P、K配比为，即氮(N)、磷(P2O5)、钾(K2O)用量分别为157.5、77.4、260.38 kg/hm2时，甜瓜果实中Vc的含量可达25.32 mg/100 g。

Abstract: The article aims to study the effect of balanced fertilization of nitrogen, phosphorus and potassium on the Vc content of melon by means of quadratic component rotational design. The mathematic model of balanced fertilization was established. The optimal quantity of fertilizer, the effect of single factor and the interaction effect were studied. The results showed that N and P, N and K, and P and K had significant interaction effects, and the right fertilization ratio could improve the Vc of melon fruit. According to the analysis, the ratio of N:P:K was 2.03:1:3.36, and the amount of N, P2O5 and K2O was 157.5, 77.4 and 260.38 kg/hm2, respectively, and the Vc of melon fruit was 25.32 mg/100 g.
