Two and a half months before and after the beginning of spring each year is a good time for grafting fruit trees. Temperatures began to rise after the beginning of spring, root activity began to absorb water and nutrients, the rootstock began to sprout, and the scion is still in the dormant state is the best period of grafting fruit trees.
Scion selection
The improved varieties are the central link of high yield and high quality. The scion should select the elite tree. Use scabs that are one year old, robust and disease-free. A branch full of branches and shoots in the middle of the tree crown.
Preparation of stock
The tree to be used as rootstock a few days before grafting should be fully watered. The purpose of irrigation is to strengthen the root pressure (commonly known as Sheung Shui) and promote the formation of layer activities to increase the survival rate of grafting.
Grafting method
The scion method usually has only 2 buds, and the cut above the cut buds is 45 degrees. The upper buds and buds are at the same level, and the lower ones are equal to the buds. Only a thin layer of wood can be removed during long cutting, so that the wooden thin-walled cells that have the ability to divide can be exposed, which is conducive to healing and cannot be cut too deeply. The effect of excessive depth is not good. The length of the long mouth is about 7 centimeters long, and the opposite counter-mouth is inclined at 45 degrees. Cuts are mainly used for relatively thick stocks of rootstocks. The height of the ground is determined by the tree, and the stock is selected to be cut in a relatively smooth place. The cut is smooth, and when the knife is selected, the knife is selected on one side, slightly wooden, about 7 cm deep. The length of the cut and scion cut is equal. Place the scion in line with the forming side of the rootstock. Applicable to Pingguo, pear, peach, apricot, plum and other fruit trees.
The splicing method uses 2 buds on the scion, cuts about 7 centimeters on both sides, and narrows on both sides with a narrow width. Cut the buds on the narrow side. It is advisable to cut the height of the rootstock by 2-5 inches. Cut the rootstock first with a knife and open it with a knife. Insert the scion into the side of the rootstock, peel the skin, and care for the heart. One side of the layer is aligned and the film strips are tied tightly.
Post-grafting management
After the fruit trees are grafted and survived, they grow faster and the new shoots are more tender and easily blown by strong winds. You can prevent the fruit trees from being blown off by tying bamboo shoots near the tree or upright branches. Spring weather is prone to locusts in the dry season and pesticides are used to control locusts. Create good growth conditions for grafted fruit trees.
