Method 1:
Pruning method in young tree period: Young peach trees grow vigorously, the top advantage is obvious, many branches are in vain, and new shoots tend to grow more secondary branches, so the crown expands rapidly, but it is also prone to unclear branches, disorderly growth and uneven growth.
The main task of plastic pruning in this period is to quickly expand the crown, cultivate the backbone branches and fruiting branches, strive for early fruiting, and lay a good foundation for long-term high yield in the future. When pruning, we should pay attention to light cutting and slow release, enlarge the crown, and combine pruning in winter and summer to promote its fruiting branches in the lower part and accelerate its formation and early fruiting.
Method 2:
Pruning method at the first fruit stage: 2-3 years after the young tree stage, the first fruit stage can be entered. During this period, the growth is still very vigorous, the crown is expanding, the fruiting branches are increasing year by year, and the yield is also gradually increasing.
The main tasks of pruning at this stage are: on the basis of pruning young trees, continue to adjust the subordinate relationship of branches at all levels, pick the core of strong new shoots in time, promote the growth of branches, cultivate all kinds of fruiting branches and improve early yield.
Method 3:
Pruning method in full fruit period: 6-20 year-old peach trees enter full fruit period. After the peach tree entered the full fruit stage, the crown slowly expanded, the growth of new shoots weakened, all kinds of branches were complete, the tree shape was complete, and most of the elongated branches at all levels had become strong fruit branches with full flower buds; Medium and short fruit branches account for a large proportion, and the main fruit parts turn to large and medium branches, and the yield increases year by year. With the increase of yield, the opening angle of main branches gradually increased, some branchlets on the backbone branches gradually decreased, and holes began to appear bare.
The main tasks of pruning in this period are: to maintain vigorous tree potential and adjust the balance of main and lateral branches; Pay attention to the selection and cultivation of regenerated branches, select and retain the base branches of main branches, so that the crown can retain more fruiting parts; The extended branches of trunk branches at all levels should be cut again appropriately to delay the outward movement of load-bearing parts as much as possible; The branches that are too dense outside the crown can be properly drained to maintain good ventilation and light transmission conditions, prolong the fruiting life and improve economic benefits.
Method 4:
Pruning method of aging period: peach trees enter aging period around 20 years old. During this period, the growth of branches decreased, the annual growth of new shoots was less than 30 cm, the middle branchlets began to decline, the big branches were weak, the crown was bald to varying degrees, the top of the main branches began to dry up, the total growth decreased, the yield began to decline, and the fruits became obviously smaller.
The main tasks of pruning in this period are: renewing weak backbone branches and promoting the emergence of strong new shoots and fruiting branches; Selecting, retaining and cultivating tendrils with suitable growth positions for renewing the aged main branches; At the same time, attention should be paid to renewing the fruiting branches in the inner cavity of the rejuvenated crown, delaying the aging period and maintaining the economic yield. When the economic value is lost, the whole garden should be updated in time.
Peach blossom (scientific name: almond? Rosaceae, peach. Small deciduous trees; The leaves are narrowly ovoid to lanceolate, with a length of 15cm and a width of 4cm, a slender top, fine teeth at the edge, dark green luster, and nectaries at the base of the leaves; The bark is dark gray, and cracks appear with age.
Flowers are solitary, from light to dark pink or red, sometimes white, with short stalks and a diameter of 4 cm, and bloom in early spring; A nearly spherical drupe with hairy surface, edible pulp, orange-yellow with red stripes, 7.5 cm in diameter, deep pits and grooves in the core, and white seeds. Originally from China, it is widely cultivated in various provinces. It is cultivated all over the world.
It is a small deciduous tree with fruit as fruit. Flowers are visible and fruits are juicy. Can be eaten raw, peaches, canned peaches and so on. And nucleoli can also be eaten. The flesh is white and yellow, and there are many varieties of peaches. Generally, the skin is hairy, and the skin of nectarine is smooth. The fruit of "Flat Peach" is flat and discoid; "Peach" is an ornamental peach tree with many petal forms.
