(1) Check the survival, dismantling the bindings, and supplementing the buds. After about 10 to 20 days, check the survival conditions. If the buds are moist and shiny, the petioles will fall when they are touched. If the buds turn yellow and dark, the petiole is shrunken on the buds, which means that the buds do not survive. Because the base of the petioles of buds with vitality after living is separated from the layer, the buds will not dry, and no separation will occur. Therefore, the petiole will not be easily knocked off. Regardless of whether they lived or not, the bandages should be released in 15 days or so in order to prevent the tied objects from falling into the rootstock and causing the buds to be injured and affect their survival. For those who have not received the livelihood, when the stock is still able to peel off, it should be patched immediately. It usually takes 20-30 days to see whether or not it survives. After survival, the direction of the selected position is better, and the upper one that grows robustly grows and the rest is removed. For unviable ones, one should select one of the roots and retain them. The remaining ones should be cut off to allow them to grow robustly and be left as budding joints or next spring branches. (2) Protection against cold In winter, cold and dry areas should be cultivated before freezing, so as to prevent freezing damage. After thawing in the spring, it should be promptly opened so as not to affect the sprouting of buds. (3) After an anvil has survived, the anvil should be cut off at 0. cm around the bud before the sprouting in the early spring of the next year. The cuts should be cut obliquely to the back of the bud, and the cut should be close to the cut. Normal healing. (4) In addition to budding, buds sprouted from the base of the rootstock should be promptly removed. (5) Upright pillars If the local spring is windy, in order to prevent the shoots from breaking off, when the new shoots grow to 30 centimeters in length, the plastic strips can be released and a prop can be tied to the rootstocks to prevent wind blows. (6) Strengthen fertilizer and water management In order to make grafted seedlings grow robustly, they can use 7.10 kg of ammonium sulfate per acre in early May and early June. After top dressing, they will be watered, and the seedlings will be cultivated and weeded in a timely manner to keep the soil loose. Grass net. (7) Topping the grafted seedlings when they grow to a certain height, in order to promote its thickening. Prone to secondary shoots of the species, such as red light Tsui, Golden Delicious, etc., in the nursery can use the auxiliary tip plastic surgery. (8) Prevention and control of diseases and insect pests The grafted shoots are susceptible to pests and diseases and should be controlled.
