摘要
目的：探索秦艽产量-质量-肥料效应最优配方,同时建立一种新型秦艽综合评价-肥料效应推荐施肥方法。方法：将灰色关联分析和DTOPSIS法有机结合,对14个不同配方处理的秦艽样品的11个指标进行综合评价,优化出秦艽标准化生产过程的氮、磷、钾肥施用量。结果：秦艽产量和质量构成因素对氮、磷、钾肥的需求规律不同,根据其特殊需肥规律及生产需要,秦艽综合产量-质量-肥料效应最佳施肥配方为：氮肥21.49~42.03 kg/667m2,磷肥49.53~65.75 kg/667 m2,钾肥26.34~42.97 kg/667 m2。结论：可将该配方广泛应用于秦艽的规范化生产。
Objective： To find the best fertilizer formula of yield-quality-fertilizer effect,and to establish a new comprehensive evaluation-fertilizer effect method. Methods： Grey related degree analysis and DTOPSIS method were combined to comprehensive evaluate the 11 indexes of 14 fertilizer formulas of nitrogen,phosphorus and potassium,in order to explore the best dosage and ratio. Results： The fertilizer requirements of the factors which contribute to the yield and quality of Gentiana crassicaulis were different and the most appropriate rates of nitrogen,phosphorus and potassium fertilizer were 21. 49 ~ 42. 03 kg /667 m2,49. 53 ~ 65. 75 kg/667 m2 and 26. 34 ~42. 97 kg /667 m2,respectively. Conclusion： The fertilizer formula in this study can be widely used in the standardized plantation of Gentiana crassicaulis.
