Results of the experiment
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 mediums after the leaf expanding period revealed that the net photosynthetic rate of the 'luoyang red' leaves of different culture mediums was significantly different between grass peat: perlite: the 'luoyang red' net photosynthetic rate in the culture medium of charcoal = 5. The improvement of the net photosynthetic rate can better promote the carbon assimilation of the 'Luoyang red', improve the biomass of plants and further improve the quality of the 'Luoyang red' peony cultivated in a container.
As shown in FIG. 2, in example 1, examples 5 to 7 and comparative example 1, the net photosynthetic rate analysis of three-time spraying of ALA 'Luoyang red' leaves with different concentrations in the full-bloom period shows that the net photosynthetic rate of the 'Luoyang red' leaves with different concentrations of ALA has significant difference, the net photosynthetic rate of the 'Luoyang red' leaves with different concentrations of ALA is significantly greater than that of the 'Luoyang red' leaves with ALA concentrations of 30mg/L and 40mg/L, and that of the 'Luoyang red' leaves with ALA concentrations of 10mg/L and 20mg/L, and that of the 'Luoyang red' leaves without ALA, wherein the net photosynthetic rate of the 'Luoyang red' leaves with ALA concentration of 30mg/L is the maximum.
As shown in fig. 3, in example 1 and examples 8 to 11, the net photosynthetic rate of the 'luoyang red' leaf sprayed with ALA in different fertilization modes was measured during the full-bloom period, and the net photosynthetic rate of the 'luoyang red' leaf sprayed with ALA was significantly greater when the base fertilizer + foliar fertilizer and the base fertilizer + ALA were applied than when the base fertilizer was applied alone. The net photosynthetic rate of the 'Luoyang red' after the base fertilizer and the leaf fertilizer are applied for 2 times plus the ALA (3 times) is obviously greater than that after the base fertilizer and the leaf fertilizer are applied for 1 time plus the ALA (2 times).
In conclusion, the method for improving the ornamental quality of the 'Luoyang red' peony cultivated in the container can improve the ornamental quality of the 'Luoyang red' peony cultivated in the container.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
