The buds should be selected from the middle of the scion, and the upper buds and the lower buds should not be used. Bud size should be appropriate. However, it should be noted that the sprout must have vascular bundles (commonly known as bud pads), otherwise it is difficult to survive. Therefore, when cutting the buds, care should be taken to take a small amount of xylem, and budding can generally be used as a shield or ring block. Such as the shield-shaped buds length of about 1.5 to 2 cm, ring block shape as the rootstock and bud size flexible grasp.
When the grafting method is grafted, it is necessary to first select the rootstocks so that they can be harvested. Long-range harvesting (buds) should pay attention to moisture. Buds and more use of "D" shape or ring two methods. After cultivating the rootstock, the rootstock was cultivated 10 centimeters high and 10 to 15 days old. The survival rate was checked. If the buds are fresh and light green, the petioles touch and fall, indicating that they have survived. For unfilled ones, they should be reconnected on the back surface of the rootstock. The seedlings that are budded in the autumn of last year should be 18 to 20 centimeters after the buds are in the spring. At the interception (ie live pile), untie the tie. Three or four prunings in the summer, cutting off new branches on the rootstock. When buds reach a new height of 8 to 10 cm, they should be tied to the living column near the base to prevent breakage. When they grow to 20-25 cm, they are tied again at the upper end until they are newly grafted into lignified wood. Living column. New seedlings can continue to stay in Daejeon to grow large seedlings.
Precautions The key to survival of budding is that the forming layers of both buds and rootstocks should be in close contact with each other to make them heal firmly. Therefore, the knife should be fast, the cut surface should be smooth, and it should be tied tightly when dressing. The width of the dressing should be 1~1.5 cm above and below the interface. It is advisable not to injure the bud during the operation, and to loosen after the bud has survived.
Medical Packaging bags with one side medical dialysis paper and the other side medical composite film can be respectively suitable for: EO ethylene oxide, high temperature STEAM, GAMMA cobalt CO60 radiation sterilization packaging, such as hospitals for high temperature steam sterilization or sterilization of medical devices used to hold the items to be disinfected, sterile medical device manufacturers such as Syringes and catheters, probes, gauze piece, gown, artificial bone, artificial organs, pencil knife resistance bacteria medical sterile products such as packaging, and general steam sterilization temperature for a few minutes to half an hour in 121-134 degrees, ethylene oxide sterilization for a few hours, temperature of about 55 degree, irradiation at room temperature disinfection, about 2 minutes to complete, High temperature sterilization is not suitable for PET(polyester)/PE(polyethylene) colorless transparent medical composite film, because PE itself does not tolerate high temperature, glue is not resistant to high temperature,.. Irradiation sterilization is not recommended to use PET(polyester)/CPP(polypropylene), because irradiation radiation has aging embrittlement effect on CPP, and may precipitate harmful halides. Generally, the product is put into the bag in the clean workshop such as the 100,000-level purification workshop, and then sealed the bag with the heat sealing machine, put it into the carton, and put it into the sterilization cabinet after sterilization. Then, due to different materials, the bacteriostasis warranty period is generally divided into 1 year 3 years,5 years, have done aging verification, so as to ensure that before transportation, storage until finally opened by the hospital nurse, the medical products in the bag are sterile products, no need to sterilize, can be directly used.
