Spraying insects and insects will be most vulnerable to pests after germination, and it is necessary to spray drugs in time.
In addition to the grafting on the roots for ten days after the grafting, the sprouting begins to occur. If it is not removed in time, it will seriously affect the growth of the scion. In addition to the germination, it is necessary to remove it on the small rootstock. If the large rootstock is as long as a bare belt, a part of the germination should be selected at the appropriate part. In the second year, if the rootstock is thicker and the joint is smaller, Do not erase all of them, and keep a part of the part farther from the joint to facilitate long-leaf rooting.
After 10 days of grafting, it is necessary to check in time, and it is necessary to make timely repairs for those who have not survived.
Loose and untied. When the new shoot is 30 cm long, it should be loosened in time, otherwise it will easily 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 completely removed.
When the wind is tied for the first time, the wooden stick with a diameter of 30 cm and 80 to 100 cm is tied to the rootstock, and the new end is tied to the upper end. Each joint is bound with a stick. In case of windbreaking. The grafting of the lived piles by the abdomen connection method can directly bind the new shoots to the live piles.
Topping the heart at the end of August to promote the maturity of new shoots and improve cold resistance.
The saplings grafted with saplings should be topdressed in the middle and late May, and the tall trees will be topped after the new shoots are stopped in autumn. All types of grafted trees are sprayed from August to September (0.3% potassium dihydrogen phosphate). 2~3 times, it is good to prevent wintering and the formation of female flowers in the next year. At the same time, we must do a good job in soil management and weed control.
