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 explore the optimal yield-quality-fertilizer effect formula of Gentiana macrophylla, and to establish a new comprehensive evaluation of Gentiana macrophylla-Fertilizer effect. Methods: The gray correlation analysis and DTOPSIS method were combined organically to evaluate the 11 indicators of 14 samples of Gentiana macrophylla treated with different formulations, and to optimize the application of nitrogen, phosphorus and potassium fertilizers in the standardized production of Gentiana macrophylla. Results: The yield and quality components of Pinus massoniana had different requirements on the nitrogen, phosphorus and potassium fertilizers. According to their special requirements of fertilizer demand and production, the optimal fertilization formula of comprehensive yield-quality-fertilizer effect was as follows: nitrogen fertilization 21.49-42.03 kg / 667m2 , Phosphorus fertilizer 49.53 ~ 65.75 kg / 667 m2, potassium fertilizer 26.34 ~ 42.97 kg / 667 m2. Conclusion: The formula can be widely used in the standardized production of Qinhuang.
