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.
CONCLUSIONS
The fertilizer formula in this study can be widely used in the standardized plantation of Gentiana crassicaulis.
