How to prevent the “false holidays†phenomenon in the rose season The fall is a good time for the tender shoots in the Chinese rose. At present, cuttings are still the main method of breeding rose flowers, which not only can maintain the characteristics of the rose varieties, but also high propagation coefficient, short production cycle, less investment, quick effect, still used by the majority of flower farmers. However, during the cutting process of the Chinese rose, “false living†phenomenon often occurs due to lack of experience or improper method. That is to say, when the Chinese rose cuts for 5-10 days, the buds on the cuttings have sprouted or drawn leaves, appearing to be alive, and may soon die and die. In order to avoid the emergence of “false living†in the rose season, first of all, when selecting cuttings, it is not possible to select branches with sprouting buds as cuttings. Especially in the growing season with tender branch cuttings, attention should also be paid to the high ripeness of the stalks, and the full and unsprouted branches of the buds are used as cuttings. If it is urgent to make use of cuttings that have sprouted on the axillary buds, and if there are more than enough lengths, the sprouted section may be cut off and reused. In the case of short branches, the germinating axillary bud can be removed with a knife or 1/3 of the bud to completely inhibit its development, so that the lower axillary bud germination. In this way, it can promote its roots and sprout buds. Secondly, in order to have the roots of the rose cutting blade, we must not only grasp the appropriate temperature and humidity, but also pay special attention to the fact that the temperature of the cutting bed medium is 1-2° C. higher than the air temperature. Adjusting the internal transfer of nutrients to the lower end of the cuttings to provide rooting for the lower part of the cuttings may encourage the roots of the cuttings to grow hair. Thirdly, especially in the autumn, it is a good time for the tender cuttings of the Chinese rose. It is very important to protect the mother leaves and prevent the shedding of the tender branches during the growing season. Because the mother leaf is now responsible for the formation of callus during the survival of the cuttings, the production of adventitious roots and the supply of nutrients for the sprouts of the sprouts. Therefore, it is important to ensure that the mother leaves do not fall off, especially for autumn tender shoots. It must be noted that cuttings must not be cut from diseased mother plants, and seedbeds and media should be strictly disinfected and sterilized, and they should be able to see the light as soon as possible to ensure ventilation of the seedbeds and ensure the improvement of the survival rate of cuttings. At present, it is during the autumn tender cuttings of the Chinese rose that various preparations should be made as soon as possible. Careful operation according to the above requirements will surely increase the survival rate of cuttings in the Chinese rose.
