And (3) counting and comparing the four cutting methods, wherein the growth conditions of the cutting seedlings refer to attached figures 1-8, and the specific rooting data conditions refer to the following table 1.

TABLE 1 rooting data for four cuttage methods

Note: the average rooting time refers to the time required for the average root length to be more than or equal to 0.5 cm;

the rooting quality index is the comprehensive index for evaluating the rooting quality, namely the rooting rate multiplied by 50% + the average number multiplied by 25% + the average root length multiplied by 25%.

As shown in fig. 1 and fig. 2, the celastrus angulatus is difficult to root by cutting with main branches, and the cutting slips are easy to infect, black rot, wilting and the like.

As shown in figure 3, the medulla of the celastrus angulatus cutting shoot is in a semitransparent cross shape, the medulla has high water content and is not full of wood, and the incision is easy to be infected or generate harmful substances due to the activity change of peroxidase. As shown in fig. 4, after the main branches are cut flatly, the cutting slips do not turn black; as shown in fig. 5, after the main branches are obliquely cut at 45 degrees, the cutting slips turn black; therefore, the medulla of the main branch of the first coronary rattan is not full, and the black rot of the cutting shoot is easily caused by infection; the cut area of the cutting slips can be effectively reduced by adopting flat shearing, so that the occurrence of infection and black rot is reduced.

As shown in fig. 6, the two cuttings on the right side are made by using the main branches and are all blackened, while the cuttings on the left side are made by using the side branches, so that the blackening phenomenon does not occur, and as can be seen, the side branches are not easy to be black and rot, and the main branches are easy to be black and rot. As shown in FIG. 7, the lateral shoot forms callus easily and takes root, but the cut under the cutting shoot is still susceptible to infection and gradually becomes black rot.

As shown in FIG. 8, the 45 degree oblique cutting of the lower cut of the cutting on the left side still causes infection and has a small number of roots, while the flat cutting of the lower cut of the cutting on the right side does not cause black rot and has a large number of roots.

The statistics of the rooting data of four embodiments in table 1, which adopt different cutting methods respectively, show that: the main branches are adopted for conventional cuttage, the rooting time of the cutting slips is long, and the cutting slips are easy to black rot or wilting, so that the rooting rate is low, and the rooting quality is not good; the rooting rate of the main branch and the lateral branch in cuttage is obviously different, the lateral branch in cuttage is easy to generate callus, the rooting rate is higher, and the rooting of the lateral branch can be promoted more by treating the indolebutyric acid with the same concentration than by treating the naphthylacetic acid.

Compared with the first three methods, the high-efficiency cutting propagation seedling raising method shortens the rooting time, obviously improves the rooting rate of the cutting and obviously improves the rooting quality. Through reasonable strong seedling cultivation, the young cutting seedlings germinate fast and grow rapidly, and the method is suitable for large-scale production and application.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
