采用计算机模拟混色技术,结合正交设计,定量测定了有翅桃蚜Myzus persicae(Sulzer)对青(C)、洋红(M)、黄(Y)和黑(K)4色成分模式混合色的选择性反应。第1组L25(56)试验结果表明,因子效应顺序为:Y﹥M﹥K﹥C。最佳理论混合色参数为C=25%、Y=25%、M=100%、K=0,模拟色板的叶色竞争系数(LCC)达77.78%。第2组L16(45)正交试验结果表明,当C、M、Y、K分别在10%～40%、10%～40%、85%～100%和0～15%区间变化时,对所有处理的叶色竞争系数均无显著影响。模拟色板叶色竞争系数与黄色成分和黑色成分的回归方程分别为LCC=0.0390Y2-0.1875Y+0.5591(R2=0.9913)和LCC=0.0163K2-0.1237K+0.6176(R2=0.7926)。
Using computer simulation of color mixing technology, orthogonal design was used to quantitatively determine the mixed color of Myzus persicae (Sulzer) with four color components of cyan (C), magenta (M), yellow (Y) and black Selective reaction. The first group of L25 (56) test results showed that the order of the factorial effect: Y> M> K> C. The optimum theoretical mixed color parameters were C = 25%, Y = 25%, M = 100% and K = 0. The color competition coefficient (LCC) of the simulated color plate reached 77.78%. The results of orthogonal experiment of L16 (45) in group 2 showed that when C, M, Y and K were changed from 10% to 40%, 10% to 40%, 85% to 100% and 0% to 15% No significant effect on leaf color competition was observed for all treatments. The regression equations of leaf color competition coefficient and yellow and black components of simulated swatch were LCC = 0.0390Y2-0.1875Y + 0.5591 (R2 = 0.9913) and LCC = 0.0163K2-0.1237K + 0.6176 (R2 = 0.7926), respectively.
