Seizing the opportunity is generally more appropriate in September, and different regions can be advanced or postponed as appropriate. If the buds are connected too early and the sprouting development is not yet complete, the rootstocks are in a vigorous growth stage, the accumulated nutrients are less, the bud survival rate is low, and the buds are prone to freeze damage after germination. If buds are picked up too late, healing is difficult later and the survival rate is low. It is preferable that buds at the upper end of budding shoots and budding buds at the lower end should not be used for budding, and those full and full buds in the middle portion of the shoots should be selected as sprouting buds. It should be noted that the bud piece is too small to survive afterwards; the bud piece is too large to be easily injured when inserted into the rootstock interface, and the survival rate of poor contact is low. When cutting the buds, care should be taken to protect the bud pad and a small amount of xylem. The buds should be cut into shields or ring blocks, and the buds of the shields should be 15 to 20 mm in length. The size of the buds in the ring block shape can be adjusted according to the thickness of the rootstock and budding shoots. Attention method When grafting, it is necessary to handle the rootstock and then cut the buds, then pick them up, in order to maintain the water and improve the survival rate. Using the "T" shaped bud connection, the "T" shaped mouth can be cut at the depth of 30 to 50 mm from the dead wood, and the depth can be seen in the xylem and the bark can be peeled off. Then, the root bark is carefully peeled off with the tip of the knife and the The buds with shields and petioles are quickly embedded, and they are tied tightly with plastic tapes with a width of 10 mm. Only the buds and petioles are exposed. The width of the dressing is preferably 10 to 15 mm above and below the incision, and 100 mm after the buds are grafted. After approximately 15 days, the earth was opened and the survival situation checked. If the shoot is fresh greenish and the petiole touches down, it means that it has survived. If it does not survive, it should be re-sprouted on the back of the rootstock. Strengthen management of nursery stocks that are harvested in the fall. After the spring of the second year, cut the stems 180 to 200 mm above the buds and untie them. 3 to 4 prunings in the summer, cut branches from the rootstock. When the budding shoots are 80 to 90 mm long, they are tied to the live pile near the base. When it is 200 to 230 mm long, it should be tied once more at its upper end. After cutting and lignifying, the live piles are cut off, and large seedlings can be kept in the field.
An anesthetic (or anaesthetic) is a drug to prevent pain during surgery, completely blocking any feeling as opposed to an analgesic. A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesia, although others are used commonly by all disciplines. Anesthetics are categorized into two classes: general anesthetics, which cause a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body while maintaining consciousness. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. We produce anesthetic raw materials like tetrcacain, lidocaine prilocaine. These three anesthesia products are in commercial quantity.
