After the fruit trees are grafted, they become semi-emerged seedlings. The spring branches and shoots are buds and then the nursery is harvested in the autumn. However, in the autumn, the budding seedlings need to be planted for one year. In order to make grafted seedlings grow normally and improve the survival rate of grafted seedlings and seedling wood, a series of management measures are needed. First, cut the anvil. In the spring of the second year of budding, cutting the anvil before budding and sprouting, the secondary cutting anvil method is generally used: for the first time, 10 cm anvil piles are left above the sprouts. This section is used as the pillar for the bud grafting seedlings and can be used later. The buds are connected to the seedlings, and when the second bud grafted seedlings and the rootstock are firmly combined, they are usually cut off from the base in the middle or late July. Second, in addition to Meng. When buds are cut to the anvil, a large number of sprouts will occur at the base of the rootstock. If they are not erased in time, they will inevitably affect the growth of the grafted seedlings. In addition to germination, it takes 2-3 times. When removing anvil buds, be careful not to bruise the grafting site and injure the grafted seedlings. Third, untie the tie. The autumn bud connection method releases the tie bar before the budding in the second year of the spring (about 20 months of the first month). After the branch connection method is applied to the scion, the branch grafting height is about 20 cm. When the interface is initially healed, the tie bar is removed. Unlocking is not timely, it will form scars, easily broken. Fourth, top-dressing irrigation. During the period of June-July, 1-2 times of topdressing, 10-15 kg of urea per acre can be traced, and water can be used to lift the seedlings. It is also possible to dig trenches buried in the soil 2 inches away from the original seedlings, and timely irrigation after top dressing. In order to make full use of chemical fertilizers, 0.3-0.5% urea solution can also be used for foliar spray. V. Prevention of pests and diseases. When budding shoots shoot new shoots, they are often harmed by insects such as ground tigers. They can be killed by carbofuran. They use 2.5-3 kilograms of mu, and they spread herbs between buds. The effective period is up to 40 days.
