摘要(Abstract):

[Objective] To study the optimal fertilizer techniques for standardized cultivation of Plantago asiatica L. [Method] Through the combination design of quadric rotation, the regression model of its production and the four elements like N, P, K and organic fertilizers was set up, the optimization of the mixed fertilization was determined by the application of DPS data base. [Result] The regression model was founded as: =2 937.44+105.46X1+17.06X2 +62.69X3 +265.18X4 -251.17X12 -80.01X22 -150.62X32 -55.67X42 +22.75X1X2 +22.75X3X4. Using 3 450 kg/hm2 as the critical value of system optimization scheme, the optimal mixed fertilization was the following: N fertilizer (urea) 247.65-314.81 kg/hm2, P fertilizer (calcium superphosphate) 346.05-553.95 kg/hm2, K fertilizer (potassium sulfate) 213.3-340.425 kg/hm2, organic fertilizer (digest pig manure) 32 737.5-35 782.5 kg/hm2. [Conclusion] The fitting degree of this formula is good enough to reflect the relationship between its yield and N, P, K and organic fertilizers.
