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.
