Abstract
Objective: To optimize the nitrogen, phosphorus and potassium fertilization models of Atractylodes japonica to offer a scientific basis for its standard cultivation and the specialty fertilizers.
Methods: Annual and biennial Atractylodes japonica were chosen in the experiment. By using three-factors, quadratic saturation-D optimal design, the effects of nitrogen, phosphorus and potassium on height, rhizome traits and active constituents of Atractylodes japonica were studied.
Results: Considering the production and active constituents,the optimum plan of nitrogen, phosphorus and potassium fertilization model was selected as N0P2K2（ N 0 g/m2,P2O540. 227 g / m2,K2O 40. 227 g / m2） and N1P3K3（ N15. 939 g/m2,P2O567. 467 g / m2,K2O 67. 467 g / m2）. By means of regression equation with nitrogen, phosphorus and potassium ratio and production（ rhizome fresh weight） of Atractylodes japonica, potassium was the major factor in nitrogen, phosphorus and potassium single effect, and nitrogen came second. According to the regression model, the best combination of nitrogen, phosphorus and potassium was obtained. The highest fresh weight of Atractylodes japonica rhizome was 27. 4066 g when the fertilization level of nitrogen, phosphorus and potassium were 38. 4301 kg / hm2,181. 4750 kg/hm2,128. 5584 kg/hm2,respectively. The target fresh weight of Atractylodes japonica was selected as 26. 00 27. 41 g per plant according to the model optimization results, and the target production was 1 040. 0 1 096. 4 kg / hm2. In 95% confidence interval, the best fertilizer combinations were X1=-0. 2912± 0. 0825,X2= 0. 2764 ± 0. 1054 and X3= 0. 1325 ± 0. 0645.
Conclusion: According to the yield and active constituents of Atractylodes japonica, which suggest that the fertilizing amount of Atractylodes japonica artificial planting is nitrogen 46. 951 59. 320 kg / hm2,phosphorus 131. 673 155. 377 kg / hm2 and potassium 120. 091 134. 597 kg / hm2.
目的:优化苍术的氮、磷、钾施肥模式，为苍术的标准栽培和专用肥料的选用提供科学依据。方法:选用一年生苍术和二年生苍术。采用三因素二次饱和d优化设计，研究了氮、磷、钾对苍术株高、根茎性状及有效成分的影响。结果:综合考虑产量和有效成分，选择氮、磷、钾施肥模式的最佳方案为N0P2K2(N0 g/m2,P2O540)。227 g / m2,K2O 40。227 g / m2)和N1P3K3(N15。939 g / m2, P2O567。467 g / m2,K2O 67。467 g / m2)。通过与白术氮、磷、钾比及产量(根茎鲜重)的回归方程，得出在氮、磷、钾单效中，钾是主要因子，氮次之。根据回归模型，得到了氮、磷、钾的最佳组合。苍术的最高鲜重为27。施氮、磷、钾水平为38时，为4066 g。4301公斤/ hm2181。4750公斤/ hm2,128。分别为5584公斤/款hm2。选取苍术的目标鲜重为26。00 27。模型优化结果为41 g /株，目标产量为1 040。2010年。4 kg / hm2。在95%置信区间内，最佳施肥组合为X1=-0。2912±0。0825年,X2 = 0。2764±0。1054 X3= 0。1325±0。0645.结论:根据苍术的产量和有效成分，建议苍术人工种植的施肥量为氮肥46。951 59。320 kg / hm2，磷131。673年155年。377 kg / hm2，钾120。091年134年。597 kg / hm2。
