In addition to sprouting, it should be carried out at any time. For small rootstocks to be removed from the net, such as baldness and longness on large stocks should be selected in the appropriate part of the bud, the second year of grafting, such as thicker rootstock and smaller joints, Don't wipe out all of them and keep some of them away from the joints to benefit the long leaves. Supplementary Ten days after grafting, it must be checked in time. Loosen and untie Generally, when the new shoots grow to 30 centimeters in length, they should be loosened in time. Otherwise, it is easy to form scars and wind folds. If the wound does not heal, it should be reattached and checked again after 1 month until the wound is completely healed and then removed. Tying sticks and windproof At the same time when they were loosened for the first time, they were tied to the rootstock with a wooden stick 30 centimeters in length and 80-100 centimeters in length. The upper end was to be tied to the new one. Each joint should be tied with a stick to prevent wind deflection. The method of leaving live grafts by means of abdominal connection can be used to directly attach new shoots to live piles. Topping At the end of August, picking up the heart to promote the maturity of new shoots and improve the ability to resist cold. Sapling Grafting and Dressing The saplings must be top-dressed in mid-and late-May, and the big trees should be top-dressed after the new shoots are stopped. The grafted trees of various types will be sprayed (0.3% potassium dihydrogen phosphate) for 2-3 times in August-September.
