摘　　要：采用二次通用旋转组合设计,多点田间试验,以及模拟寻优,得到鲜归亩产高于500kg,亩纯收益大于500元的最佳农艺组合:每亩密度6860～7600株、施纯氮18.75～22.2kg、五氧化二磷9.1～11.1kg、氧化钾4.46～5.37kg。氮、磷、钾的配比为1:0.49:0.24。Using two-time general rotation-constitution design, the math-mdele has been founded about Angelica sinensis prodution efficiency and quantity of nitrogen, phosphorus and potassium to use by doing experiments in many different spots and production demonstration for testing and verifying. Accordin to the modle, computer is used to simulate the better, through which people can get fresh Chinese angelica over 500Kg per mu and also net income over 500 yuan per mu. It shows that this is the best combination. 95% density riliabitity for this plan is 6860 -7600 plants, pure nitrogen 18. 75-22. 2 Kg,P2O5 9. 1-11. 1 Kg and K2O 4. 46-5. 37 Kg one mu. Proportion for nitrogen, phosphorus, potassium is 1 : 0. 49 : 0. 24.
