SONG He et al (Agranomy College , Anhui Agriculture University, Hefei, Anhui 230036)  
[Objective] The study was to provide a theoretical base for the generalization and normalizing cultivation of Wanmai 48. [Method] The influence of different application rates of N,K,P,density and sowing date on the yield characters of weak gluten wheat Wanmai 48 were investigated with multi-quadratic orthogonal rotational regressive design.[Result] The influence of testing factors on yield in order was N application rate K application rate sowing date density P application rate.The mathematical model between testing factors and yield characters was set up,and the interaction of testing factors and its optimum combinations were analyzed.With the yield target of 7 796 kg/hm2,the sum of 1 490 combining programs were simulated and established.The corresponding density,application rate of N,K,P and sowing date for 95%confidence interval distribution were 2.946×106~3.054×106 basic seedling/hm2,157.08~164.64,85.62~89.55,198.08~207.90 kg/hm2 and 1st to 3rd in November resp.[Conclusion] The optimum cultivation combinations influencing the yield of Wanmai 48 were put forth,which could be used to guide production.
