Experimental results
As shown in fig. 1, in example 1 and comparative examples 1 to 3, the net photosynthetic rate analysis of the 'luoyang red' leaves of different culture substrates after the leaf expansion period showed that the net photosynthetic rates of the 'luoyang red' of different culture substrates have significant differences, and the net photosynthetic rates of the 'luoyang red' leaves of different culture substrates are different from each other in turf: perlite: the net photosynthetic rate of 'loma red' in the charcoal = 5:1:0.5 culture medium was significantly greater than that of the other culture medium. The improvement of the net photosynthetic rate can better promote the carbon assimilation of 'Luoyang red', improve the plant biomass, and further improve the quality of vessel cultivation of 'Luoyang red' peony.
As shown in fig. 2, in example 1, examples 5 to 7 and comparative example 1, the net photosynthetic rate analysis of 'luoyang red' leaves sprayed with ALA of different concentrations was measured three times in the full open period, and it was found that the net photosynthetic rates of 'luoyang red' sprayed with ALA of different concentrations were significantly different, and the net photosynthetic rate of 'luoyang red' sprayed with ALA of 30mg/L and 40mg/L was significantly greater than the treatment of spraying ALA of 10mg/L and 20mg/L, and significantly greater than the treatment of not spraying ALA, wherein the net photosynthetic rate of 'luoyang red' treated with ALA of 30mg/L was maximum.
As shown in fig. 3, in examples 1 and 8 to 11, the net photosynthetic rate of applying the base fertilizer + the foliar fertilizer and the base fertilizer + the 'luoyang red' of the ALA was significantly greater than that of applying the base fertilizer alone, as measured by the different fertilization methods and the 'luoyang red' leaf of the ALA sprayed. The net photosynthetic rate of 'Luoyang red' for applying base fertilizer + foliar fertilizer (2 times) +ALA (3 times) is significantly greater than for applying base fertilizer + foliar fertilizer (1 time) +ALA (2 times).
In summary, the method for improving the cultivation and ornamental quality of the 'Luoyang red' peony container provided by the invention can improve the cultivation and ornamental quality of the 'Luoyang red' peony container.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
