Peach grows vigorously, has strong sprouting force and branching ability, prone to a large number of leafy branches, developmental branches and leggy shoots, and can draw multiple secondary shoots, so that the canopy shades, the proportion of high-quality flower buds is reduced, and the fruit setting rate is not high. The decline in fruit quality is a common problem in Taoyuan. However, reasonable pruning in the peach growing season (mainly from sprouting to shoot growth stage) can not only inhibit the apical dominance, but also reduce the branching area, so that the young trees can be formed early as early as the end of high yield canopy, but also can control the invalidity of the adult tree. Growing, improving ventilation and light transmission conditions, increasing fruit yield and quality, and also playing an important role in renewal and rejuvenation of aging trees. The flower buds of peach trees began to differentiate from July to August of last year, and they were completely formed before flowering in late spring. The flower buds at the periphery of the canopy where there is sufficient light are numerous and full, and the fruit that is born is large and bright in color. The flower buds in shades within the canopy are thin and sparse, and the fruit quality is poor. During pruning, according to the characteristics of the growth characteristics of peach trees, the balance between tree vigor, strong and weak, and the relationship between vegetative growth and reproductive growth should be adjusted so that strong branches are cut, weak branches are lightly cut, and strong branches are left with weak shoots. The weak branch leaves strong buds. After the budding of the peach trees until the new shoots grow to 5 centimeters, it is necessary to erase buds and disturb the tree-shaped shoots as early as possible. If the saplings are unfruitful, the buds of the extensions should be in a suitable position and grow robustly, leaving 1 to 2 branches per branch; the leaves branching on the main branch can be left as much as possible. In the rapid growth stage of new shoots, in order to promote secondary branches, it is necessary to timely pick up the heart, the main lateral branches can be left to pick up about 45 centimeters, and the auxiliary branches for the retention in the crown can be picked up at 30-40 centimeters. If it is empty or eccentric, select the appropriate length of branches to accelerate the cultivation of the crown, but the length of the growth should not exceed 50 cm, can be timely picking the heart, so that the branches of the oblique growth. In addition, twisting shoots or branches can also be used to mitigate the growth of leggy branches. Rich trees should keep more shoots, and each branch can leave 3-4 shoots at the time of 30 centimeters. The new shoots should be spaced 8-10 centimeters to ensure that the new shoots are full and grow old. The number of differentiation. Young shoots growing from the lower trunk of young fruit trees should be cut off as soon as possible, and the useless erect standing branches of the canopy of the tree crown should be removed. The result tree needs to eliminate the debilitating result of the previous year and the serious pests and branches. The flowering fruit that did not bear fruit in the year left 3-4 buds short. Make it an early result of the next year. The general short-term should be carried out in May-June. It is advisable to short-cut the apex of the unliganded shoot. After 7 months, the flower buds began to differentiate and the trees were prone to flow. It was not appropriate to perform short cuts and sparse shearing. Peach blossoms have a large amount of flowers, and the fruit setting rate is also very high. Because of the large amount of fruit contained in the tree, the fruit is small, the quality is poor, and the tree vigor is aging. Therefore, thinning and thinning fruit is an important part of the scientific cultivation of peach trees. The sparse flowering should be carried out in the flowering period after the peach blossoms are large and the pollination is sufficient. In the case of poor pollination, low-temperature freezing or rainy days, it should not be sparse, so as not to reduce the yield. The sparse flowers are misshapen flowers, cluster flowers, and stunted multi-stalked flowers. Peach fruit thinning can be carried out one month after flowering and before hard peach nucleus. Fruits with high fruit setting rate, stable yield, or weaker tree vigor can be sparse as early as possible. The condition of fertilizer and water is good or the tree should be sparsely sparse. In addition, according to the distribution of leaf curtains and the growth potential of branches to retain fruit, adhere to weak branches and stay less, strong branches and stay more, leaves a thick layer of more stay, small fruit varieties stay, small fruit varieties stay. Flowers and fruit branches can be left 3 to 4, the middle and short fruit branches left 2 to 3, the branches of the apricot fruit left 1 to 2, the weak branches of the order can be completely removed. The objects of fruit thinning are mainly small fruit, malformed fruit, diseased fruit, mechanically wounded fruit, and dense fruit, etc. The fruits on both sides of the fruit branch and downward growth are selected. When fruit is thinned, use fruit cuts or branches to protect the peaches and shoots from damage.
