[0047] Example 1

[0048] Preparation method of wolfberry-licorice-based carbon quantum dots MIX

[0049] First, after the wolfberry and licorice were crushed, 200 mg of wolfberry powder and licorice powder were accurately weighed and mixed thoroughly. Subsequently, 20 ml of distilled water was added to the mixture, and the mixture was transferred to a 50 ml polytetrafluoroethylene autoclave. The reaction conditions were set to a temperature of 160 ° C, and the reaction was continuously heated and stirred for 6 hours. After the reaction was completed, the reactor was allowed to cool naturally to room temperature. The reaction solution was taken out of the reactor and divided into multiple 1.5 ml centrifuge tubes. Each tube of sample was centrifuged at 5000 rpm using a centrifuge for 60 minutes to completely separate the solid residue from the supernatant. After the centrifugation, the supernatant was taken to obtain a brown liquid with a sweet aroma, which was LWCMs (wolfberry-licorice-based carbon quantum dots MIX). In order to maintain its stable properties, LWCMs were finally stored in a 4 ° C refrigerator for subsequent use.

[0050] Example 2

[0051] Example 2 is substantially the same as Example 1, with the only difference being that: 400 mg of wolfberry and licorice powder are used, the heating temperature is 170° C., the time is 7 hours, the centrifugal force is 5000 rpm, and the centrifugal time is 80 min.

[0052] Example 3

[0053] Example 3 is substantially the same as Example 1, with the only difference being that: 100 mg of wolfberry and licorice powder are used, the heating time is 5 hours, the centrifugal force is 3000 rpm, and the centrifugation time is 30 min.

[0054] Example 4

[0055] Treatment of wolfberry-licorice-based carbon quantum dots MIX on wheat

[0056] Based on the LWCMs prepared in Example 1, the following operations were continued: First, wheat seeds with full grains, uniform size and no damage were selected as experimental objects, and experimental plots were set up. The row length of each plot was 3 meters, the row spacing was 20 cm, and the total area was 3m 2 On October 2, 2023, the prepared seeds were sown in each experimental plot, with the distance between each seed kept at about 2 cm to ensure that they had enough growth space. After sowing, the experimental plot was irrigated at a rate of 20m 3 / mu.

[0057] When the wheat reached the critical stage of early grain filling, treatment was carried out on May 14, and two different treatment solutions were prepared: one was composed of pure water and 0.05% Silwet L-77, and the other was composed of 0.05% Silwet L-77 and 100mg / L of nanomaterials. The two treatment solutions were then evenly sprayed on the middle and upper areas of the wheat plants in their respective test plots using a 5L spray pot. The solution containing pure water and 0.05% Silwet L-77 was set as the control group.

[0058] When the wheat grew to the mature stage, i.e. 33 days after treatment, the treated wheat plants and the wheat in the control group were manually harvested, threshed and impurities were removed to ensure that the collected wheat grains were pure and free of impurities.

[0059] Example 5

[0060] Verification of the effect of wolfberry-licorice-based carbon quantum dots MIX on wheat

[0061] The appearance of the two groups of wheat grains collected was compared, such as Figure 1 shown.

[0062] In order to clearly evaluate whether the wheat quality has been substantially improved, the SupNIR-1230 near-infrared analyzer produced by Beijing Jitian Instrument Co., Ltd. was used. The changes in multiple factor parameters were then measured on the wheat grains after 33 days of treatment. Each indicator was compared with the pure water control group, and three repeated measurements were performed to ensure the accuracy and reliability of the data. Finally, the average value was taken to reduce the error, and eight corresponding coordinate graphs were drawn to intuitively show the changes in factor parameters.

[0063] Several factors include: Figure 2 ) The crude protein content of wheat grains, which is related to the nutritional value of wheat; Figure 3 ) Wet gluten content is an important indicator for measuring the quality of wheat gluten; Figure 4 ) Hardness value reflects the hardness of the grain endosperm texture and is an important factor in wheat flour quality and processing quality; Figure 5 )W value represents the gluten strength of flour. The larger the W value, the stronger the gluten. Figure 6 ) water absorption, further refining the water absorption characteristics of wheat; ( Figure 7 ) Sedimentation index, used to assess the quality of wheat flour, especially its baking performance; Figure 8 ) Falling number, which reflects the activity of α-amylase in wheat; Fig. 9) Bulk density, as an indicator of wheat grain density and fullness, the higher the bulk density, the fuller the wheat grain, and the higher the flour yield. By comprehensively analyzing the changes in these parameters, it is well-founded to prove the significant effect of the wolfberry-licorice-based carbon quantum dots MIX on the quality of wheat grains.

[0064] Although the above embodiment describes the present invention in detail, it is only a part of the embodiments of the present invention, not all of the embodiments. People can also obtain other embodiments based on this embodiment without creativity, and these embodiments all fall within the protection scope of the present invention.
