摘　　要：以厚皮甜瓜"蜜世界"为试材,采用三因素五水平二次回归通用旋转组合设计,通过计算机模拟构建数学模型,探讨氮、磷、钾肥的主效因子效应、单因子效应、互作效应、边际产量和最佳施肥量,以期探寻日光温室厚皮甜瓜最佳施肥方案。结果表明:3个因子对甜瓜产量的影响的大小顺序为施磷量>施氮量>施钾量。当施氮量为449.78kg/hm2、施磷量为449.33kg/hm2、施钾量为449.78kg/hm2时,甜瓜产量最高,可达26 097.95kg/hm2。With muskmelon ＇Honey world＇ as material ,with three factors and five levels of the quadratic General Rotary unitized design by means of computer simulation of mathematical mode! ：o explore the main factor effect of nitrogen, phosphorus and potassium, single factor effect, the interactions,the marginal yield and optimum fertilization with a view to exploring the best of muskmelon in sunlight greenhouse fertilization. The results showed that 3 factors on muskmelon yield in the order of phosphorus 〉nitrogen 〉 potassium. When nitrogen was 449. 78 kg/hm^2, phosphorus was 449. 33 kg/hm^2 ,potassium was 449. 78 kg/hm^2 ,muskmelon yield could receive a maximum yield of 26 097. 95 kg/hm^2.
