1. Check the survival and replenishment

Budding grafting can be checked about 15 days after joining the survival of the situation, if the bud pieces of the skin color green, the bud of the petiole with a finger to touch that fall, it is said to have been successful; if the petiole does not fall, the buds are dry, that did not survive, you need to make up for the grafting immediately (Figure 70).

Figure 70 budding to the survival of the situation

2. untied

Budding in about 3 weeks after the catch can be untied, branching in the catch 45 to 60 days after the untied. Late fall budding year do not have to untie, the next spring and cutting anvil at the same time.

3. cut anvil

Summer budding cultivation of fast-growing seedlings should be cut anvil 7 to 10 days after picking up, fall budding can be cut anvil in the spring of the second year, cut anvil should be cut in the upper bud 0.3 to 0.5 cm.

4. In addition to budding

Branching and budding anvil cutting is easy to sprout a large number of new branches from the rootstock, should be removed in a timely manner, so as not to affect the growth of branches or buds (Figure 71).

Figure 71 in addition to sprouting

5. stand (tied) pillar

Budding, branching or high trees, in windy areas, when the buds or new shoots up to 30 centimeters should be set up to protect the pillar in order to prevent the wind from blowing off.

6. Shaping

Budding, branching seedlings can be nursery shaping, measures include centering, thinning part of the secondary tip, secondary tip pulling branches.

For high-growth trees, shaping methods mainly include centering, control of competing branches, open angle, control of strong branches. The purpose is to quickly form a new canopy and restore yield. Trunk high grafting scion new growth is very strong, the year's growth is very large, should take full advantage of this advantage, timely treatment of auxiliary branches, can be cultivated into the ideal tree shape. Multi-head high grafted tree, in high grafting for heavy retraction, after the branch growth, it is easy to break the original branch subordinate relationship, so high grafted tree shaping and pruning need to judge the role of each branch in the crown, as the main, lateral branch preparatory branch to support its growth potential, to ensure its growth space, and other branches to control the growth potential and the size of the branch, cultivated into fruit-bearing branch groups, over-dense, but also need to be thinned out, in order to Maintain the original tree structure of the crown (Figure 72).

Figure 72 pear tree multi-head high jointing in the summer of the year, the new tips will be led to the scaffolding of the lead wire

7. Soil, fertilizer and water management

Mainly includes plowing and weeding, timely fertilization, irrigation and foliar spraying fertilizer.

8. Pest control

The main control of aphids, leafrollers, red spiders and so on.

9. Examples of management of the main stem after high grafting

Apple is a robust growth of the development of the branch as a scion, usually leaf buds, but some apple varieties of the development of the branch will also have some flower buds, grafting this situation, should be promptly thinned out the flowers, the use of the fruiting platform to cultivate a new new new tip, as shown in Figure 73.

Figure 73 flower thinning treatment

1 week after the flower thinning, the new growth resumed, the left scion in the figure issued two new tips, both formed by the original flower buds of the fruiting stage of the secondary tip formation, should be timely control of the growth of the (right) new tips, only to maintain the vigorous growth of the (left) new tips. The right scion is then treated as a secondary branch (Figure 74).

Figure 74 Growth after 1 week of thinning

The growth of new shoots can be controlled by centering as shown in Figure 75.

Figure 75 Centering of new shoots that should be controlled

After 10 days, the scion grows vigorously, but auxiliary branch growth is similar to the growth of the new main stem, creating competition (Figure 76), which needs to be controlled; and the rootstock sends out many new shoots, which need to be thinned out in a timely manner; in addition to setting up pillars (Figures 77Figures 78).

Fig. 77 After centering, the new trunk needs to be tied to the strut and the growth of auxiliary branches needs to be constantly controlled
