Study on Optimal Fertilizer Techniques for Standardized Cultivation of Plantago asiatica L.as a Genuine Chinese Medicinal Materials in Jiangxi Province
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: 7 = 2 937.44 + 105.46X1 + 17. 06X2 + 62.69X3 + 265.18X4 -251.17X21 -80. 01 X22 -150.62X23-55.67X24 +22. 75X1X2 +22. 15X3X4. Using 3 450 kg/hm1 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/hm , 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.关键词
