The girdling can effectively regulate the growth of flowers and trees and promote its flowering results. During girdling, the selection can be made at the proximal base of strong shoots or branches, and the depth is based on the thickness of the twigs, depending on whether the cortex (phloem) is cut off or the xylem is not damaged. It is generally 0.2-1 cm. 1 ringing time The garland peeling must be girdled before the flower bud differentiation, but there are many kinds of flowers and flowers, and the girdling period should be determined based on the flowering habits. Most of the flowers that bloom in the early spring and spring and summer are flower bud differentiation in the summer and autumn of last year. The girdling should be carried out from June to August. The flowering trees in the summer and autumn seasons are the new shoots that germinated in the year. The formation of flower buds can be girdled after the new shoot ceases to grow; for flowering flowers that bloom continuously for one year, girdling is performed after each floral thank. Fruit girdling should be girdled 15-20 days after flowering and before fruit drop. For example, kumquats, bergamot, ginkgo, pomegranate, papaya, generations, cockroaches, and pyracantha. In addition, girdling of branches that grow vigorously on sunny days can reduce flowering and fruit loss and increase fruit set rate. 2 circumcision species This method can be used for cutting flowers that are not easy to take root, such as Osmanthus fragrans, Chinese rose, woody hydrangea, and Pittosporum reticulata. This method can effectively increase the survival rate of cuttings, and should be selected in the current year when the operation is robust, free from pests and diseases, and completely lignified. The annual branch, after stripping 0.5-1 cm wide bark with a blade ring at its base, it is maintained for about 15 days, and then cut into the cutting program from the ring, which is more efficient than direct pruning and cutting. Rooting faster and more. This method is used for high-pressure girdling of flowers such as peony, mimosa, rubber tree, milan, camellia, azalea, champa and rims, etc. During operation, the 1-2 year old shoots were selected to be ring-skinned at a growth period of approximately 1-2 times the diameter of the shoots, scraped off the layer of woody surface, and after being dried, the girdling shoots were under a plastic film. Tighten up and wrap it up to make it into a bag, and make the ring mouth in the center of the bag, fill in wet sand or moss, and tightly fasten it. Pay attention to keep the internal moisture constantly. After rooting, cut and plant a new plant. 3 Precautions The period should be suitable for circumcision prematurely, and the excision will heal before the flower bud differentiation period, and will not achieve the effect of “cutting offâ€. After the girdling was too late, the concentration period of flower bud differentiation has passed and the effect is not obvious. Widths should be generally 1/10 of the diameter of the branches to be treated, but the girdling of the flowers does not need to heal during high-pressure propagation. The girdling width is generally 1-2 times of the diameter of the branches, and the girdling sites are too narrow. Without rooting, the wound will heal, and it will not be conducive to rooting. Depth should be appropriate for the propagation of rooting flowers, the depth of not to hurt the xylem as degree, and scraping the formation of a layer of wood surface to prevent wound healing to restore the original and affect rooting. The amount of peeling of each flower tree should be determined according to its growth potential. It should not exceed 1/2-2/3 of the total number of stem branches of the whole tree, leaving some branches without girdling, so that the root system can still obtain a small amount. Photosynthetic products, so as not to excessively weaken the tree, causing premature aging. After peeling and peeling, after management of ring peeling, it is necessary to strengthen the management of flowers and trees, supply sufficient fertilizer and water, and timely control pests and diseases to make them grow robustly. Promote flaking of flowering results, peeling should pay attention to protection, can be wrapped with plastic wrap to wrap the ring around the mouth, in about 20-30 days to check the healing of the wound, to completely remove the wound to remove the dressing in time to avoid Affects normal development. In addition, the pericutral wound should not be randomly coated, in order to facilitate the smooth healing of the wound, in particular, the excision of the mouth bactericidal antibacterial agents, some people to prevent the bacteria infection, in the wound after the circumcision coating fungicide (such as Formamide arsenic), This will cause dead branches and dead trees.
