First, master the best grafting time. The best time for grafting is from late February to mid-March each year, and it is not easy to survive prematurely. If it is too late, the scions will sprout late. The shoots will grow slowly and the flowers will not grow in the same year.
Second, master the ratio of output and joints. Practice has proved that, with multi-joint grafting, the trunk circumference, crown diameter, and total branch weight increase significantly, and the balance between the aboveground and underground parts of the tree and the ability of roots to absorb and supply can be maintained, and the survival rate of grafting can reach over 99%. The number of joints is determined by the tree's original production. Generally, for a large tree with a production of more than 200 kilograms, a scion of 500 grams of fruit is used; if the amount is less than 200 kilograms, the ratio of one scion per 1000 grams of fruit is changed.
Third, the use of Pingzhi grafting. Before the changeover, the tree was first cleared, and according to the requirements of tree shaping, some large branches and dense branches were removed. The branches to be joined should be cut in full by branches, cut flat and then grafted. Do not cut them one by one to avoid inconvenience of movement or damage to the grafted scions. The method of grafting is splicing and cutting. According to the short scion of 2 to 3 buds and the long scion of 3 to 5 buds, the traditional straight grafting is changed when grafting, and the horizontal shoots are used as rootstocks. Horizontal branches or pendulous branches, in order to facilitate the accumulation of organic nutrients, try to avoid the back of the branches. The interface is wrapped in a film and the top of the scion is sealed with wax to prevent loss of water.
Fourth, do not toss the heart and tie it at the right time. That is, new shoots growing after grafting can not be picked up, which is conducive to the top of the branches, easy to form flower buds. It is only necessary to twist the strong or competitive branches. In early July, after the interface is healed and unwound, the interface must not be healed until it is fully healed and then untied.
Fifth, set a tree to produce flowers to set the fruit. For the fruit trees grafted in the year, the winter shears were mainly cut with light shears and slow discharges. The second year of flowering, according to the age of the tree, the size of the crown, the burden of the branch, so that "a tree to set production, with flowers to set the fruit." For example, a native pear with a weight of 300 kg is grafted with 600 Fengshui pear ear buds. In the second year, the output of 300 kilograms is to be restored. According to the theoretical basis of the average fruit weight of Fengshui pear 300 grams, only 1200 flower buds can be preserved during the inflorescence separation period before flowering. All other flower buds should be removed.
Sixth, late management. Strengthen the management of fertilizers and waters, promote the development of new shoots; eliminate germination and tie-in in time; cut off the sprouts immediately after the scion survives; when the new shoots grow to 20 cm in length, the support rods should be tied in time to prevent breakage of the interface after the results; strengthen pest control, In the growing season, 0.5% urea was added every time pests were sprayed and the effect was better.
