Evaluation Of Ornamental Characters And Comprehensive Evaluation System For Miniature Potted Roses

Miniature potted rose is a popular small potted flower.It is rich in variety and variety of colors.It is suitable for office and home decoration.The production and application are developing very rapidly.The scale of professional production is growing,but due to the lack of micro-potted rose,the ornamental traits and Its adaptability research and evaluation bring certain difficulties to the screening and promotion of varieties.In this study,the analytic hierarchy process,fuzzy comprehensive evaluation analysis,and gray correlation analysis were used to observe the ornamental traits of 31 micro-potted rose varieties(Plant height,crown width,flower color,floral aroma,stem diameter,peduncle length,number of petals,flower diameter,flower shape,petal texture,double petal type,leaf color,full bloom period)and production indicators(growth potential,resistance to pests and diseases),preliminary establishment of a comprehensive evaluation system for micro-potted roses,and development of Yinchuan area The miniature potted rose pot flower production standard provides a theoretical basis for factory production.The results of this study were as follows:(1)Screening and evaluation criteria for ornamental characters of miniature potted roseThrough the evaluation and screening of the ornamental traits of miniature potted roses,the flower,flower color,floral fragrance,growth potential,petal texture,flowering period and leaf color were important evaluation indicators in the miniature potted rose traits,which were determined according to the importance of each trait.The evaluation criteria for ornamental traits of micro-potted roses were selected according to the importance of traits for the production and demonstration planting.(2)Analytic hierarchy process,fuzzy comprehensive evaluation analysis method,comprehensive evaluation of grey correlation analysis methodThe evaluation of 31 micro-potted roses by three methods showed that the results were consistent,indicating that the system was feasible for the evaluation of micro-potted roses.The comprehensive evaluation results show that in the red variety ’Massland’,’Hot Jewel’,’Sunshine Star’,’Rome’,’Hot yellow’ in the yellow variety,’Amazing jewel’,’Estoril’,’Baby Jewel’ in the white variety,’White star’,Massland gold’ in the pink variety,’tourist star ’,and 12 varieties of’Portus Cale’ in other varieties,the flowers are bright and beautiful,the growth is good,the flowering period is long,and the resistance to pests and diseases is strong.It had good comprehensive characteristics and is suitable for cultivation and production under the facilities of Yinchuan area.Red variety ’Lipstick Jewel’,’Bingo Star’,’Bari by Night’,’Jin Infinity’,yellow variety ’ Shining Star’,’Enya Terrazzo’ pink variety ’Marina’,’pink princess’other colors The 9 varieties of the variety ’Princess of infinity’ can be cultivated as a minor variety.The remaining varieties have poor overall performance,low indicators,and are not suitable for local cultivation.The results of the above-mentioned varieties are the basis for the selection of micro-monthly production in Yinchuan area.(3)Forming technical standards for the production of micro-potted rosesCombined with the evaluation system of micro-potted rose,the production standards suitable for micro-potted roses in Yinchuan area are summarized:4 to 5 plants per pot,1 to 3 small flowers per plant,8 to 10 flowers per pot,and plant height 25-28 cm.The single pot crown is 28-33 cm,and the flowering period is more than 12 days.It grows well without pests and diseases,and the pattern is neat and bright.
