为了探讨N、P、K肥料配施对甜瓜主要经济性状的影响，通过采用三因素五水平二次正交旋转组合设计，研究了N、P、K配施对甜瓜品质的影响，构建了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了分析。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品质。分析认为，当N、P、K配比为1.53∶1∶3.36，即每hm2氮（N）、磷（P2O5）、钾（K2O）用量分别为118.07、77.4、260.38 kg时，甜瓜的可溶性固形物含量可达13.34%。

For research the effect of nitrogen,phosphorus and potassium balanced fertilization on the economic traits of melon by means of quadratic component rotational design,the effect of N,P and K balanced fertilization on the quality of melon was studied . The mathematic model of balanced fertilizers was established. The optimal quantity of fertilizer ,the ef-fect of single factor and the interaction effect were studied. The results show that between N and P,between N and K,be-tween P and K had significant interaction effects,and the right fertilization ratio could improve the quality of Melon. The ra-tio of N∶P∶K were1.53∶1∶3.36,and the amount of N,P2O5 and K2O respectively were118.07 kg/hm2,77.4 kg/hm2, 260.38 kg/hm2,and the soluble of melon was 13.34%.
