Management measures after autumn bud grafting
1, check the survival rate. Usually 20-28 days after grafting can distinguish whether to survive. It can be checked from the state of sprouting and petiole, where the buds are fresh and the petioles are ready to touch. The buds were dried, the color was brown, the buds were dry, and some scions were black at the top, indicating that they did not survive. All those who have not survived should make up for it in a timely manner. 2, broken film buds. When the buds start to germinate, the graft film that carefully prevents germination is carefully picked up with the blade tip. If the buds have survived, after 7-10 days of unwinding the membrane strip, the rootstock is cut 4/5 of its diameter above the sprouts, and the rootstock is cut off from the shear, so that 1/5 of the stock is also connected with the stem, and the upper and lower moisture The nutrient is connected, and some nutrients are supplied to the sprouts. The buds are to be sprouted and the first new shoot is drawn. At least 4-5 pieces of mature leaves are used or later. After the new shoots are stopped, they will be added to the stock. All branches and leaves were cut off. 3, timely eradication of buds. The center of management is to protect the scion and promote its germination. The root buds sprouting on the lower part of the interface should be wiped off in a timely manner. At the same time, the new shoots and ears on the water branch should be removed to reduce the nutrient consumption. After the new shoot is matured, the anvil is broken 1 cm above the interface. 4, vertical pillars to protect new shoots. The young shoots of the new shoots are large and easy to be blown by the wind, and should be inserted into a "8" shape with film straps or other ropes. 5, pay attention to fertilizer management. When the spring shoots are old and ripe, they should be applied thin fertilizers. Fertilizer applied on the original crown drip line, triggering fine roots. Water should be sprayed in time when drought occurs, and drainage should be conducted to prevent waterlogging during the rainy season. China Agricultural Network Editor
