A comprehensive study evaluating the optimal mix-ing ratio of annual gram-bean mixed artificial grass in the Sanjiangyuan area
[Objective]In order to investigate the optimal comprehensive evaluation model for establishing an ar-tificial grass mixed seeding system in the Sanjiangyuan area of Qinghai Province.[Method]This paper employed three different comprehensive evaluation methods to screen suitable gram-bean mixed seeding combinations and pro-portions for planting in the Sanjiangyuan area.[Result]The test results revealed that,among the three evaluation methods chosen,the AHP hierarchical analysis method identified the ideal mixed sowing combination and ratio as Av-ena sativa + Vicia sativa(70∶30),the affiliation function evaluation method identified it as Avena sativa + Vicia sa-tiva(60∶40),and the gray correlation evaluation method determined it as Avena sativa + Vicia sativa(70∶30).[Conclusion]The best combined combination and ratio of Avena sativa + Vicia sativa(70∶30)is proposed for the alpine region,based on the the integrated gray correlation evaluation approach,considering the altitude conditions of the test area and other parameters.
