Peach trees want to produce winter cut no small look
As the saying goes, "Winter cut tree, summer cut flower." Some fruit growers believe that peach trees have strong adaptability, luxuriant foliage, and trimming need not be too careful. In fact, peach pruning in winter is an important agricultural technical measure in peach management. Through reasonable pruning, it can cultivate and maintain a good tree structure, improve the lighting conditions of trees, adjust the relationship between growth and results, and make rational use of space. , To achieve early results, high yield, stable production, high-quality production purposes. Peach Winter Trim "Three Basis" Determine the pruning plan and method based on the habit of peach 1. Peach is an extremely positive tree species. Therefore, light must be considered in pruning. Regardless of the shape of the tree, branches cannot overlap, overlaps and shading each other. To reach the growing season, you can see the light. 2. Peach trees are the result of new branches. Therefore, the old branches that have had peaches in the previous year must be removed during pruning (strong trees can remain part of the tree, single branches can be removed to remove the weak branches at the front, and the left part can be used New branch), leaving only the appearance of strong spring flowers, full 30 to 50 centimeters long flower buds, chopsticks head weight, when the new branch was next year's peach branches. 3. The peach tree has extremely strong polar growth, and it is prone to the phenomenon that the twigs on the back of the internal malleolus and the backbone branch are dead and the investigation sites are shifted out. Therefore, we must take more measures to prevent the situation, such as sparing no efforts to stay small, leave the old to stay new, stay clear before leaving, and stay behind. Determine the different tree shapes based on different planting densities of peach trees 1. Peach trees planted in high density should adopt the “main trunk shape†of 333 plants planted in 21 acres. This kind of tree management is the simplest, most convenient and most prone to high yield. 2. Peach trees that have been cultivated and weighed are originally managed according to the back-to-back level level of the tree structure. There is no cross-line or cross-over between plants. The overlap can be managed by a single-level flat-shape tree. If cross-overs have already occurred, it is necessary to select 1 to 2 small main shoots on each main branch when they are cut on the back. Small main branch spacing needs to be more than 1 meter, height should be within two meters. The total number of small branches of the whole tree can be about six, making it from a single-layer flat happy shape into a "more than one main dry." 3. Peach trees that are more sparsely cultivated should continue to be maintained as long as they do not cross or overlap. However, we must pay attention to the need to apply a new branch of 30 to 50 cm long results, the results are not short cut. Based on different tree potential, determine the amount of sticking A peach tree that grows with a moderately strong midwinter, and the branches left after the winter cut is converted into a one-meter-long peach branch, can produce 1 kilogram of high-quality peach. According to this standard, a reasonable amount of branching can be calculated based on the strength of the land, the age of the tree, and the size of the area covered during winter cutting. If the tree vigor is strong, the amount of branching and production can be slightly larger, the tree vigor is weak or the tree age is small, the coverage is less than 75%, and the branching amount and yield can be less. (Yan Shuxia) Happy peach tree winter cut should focus on slow release The purpose of the pruning peach tree winter pruning is to balance the tree vigor, branching potential and the appropriate number of fruit branches by various pruning methods so as to achieve the purpose of ventilation, light transmission, and high yield for successive years. The pruning method is mainly based on a slow-discharging pruning technique. Main technical points The main branch (trunk) of the extension of the first treatment: the extension of the first period of young trees should remove the autumn shoots (commonly known as the blind), full shoots in the spring shoots under the cut, the main branch angle with a large bud, a small angle with a bud; The adult tree depends on the length of the branch axis. Fruiting branch retention density: It is necessary to determine the fruit branch location and quantity of the resulting branch based on the age of the tree and the tree potential. The right approach is to leave little or no fruit at the back and ends of the shoots. The amount of sticks per mu should be between 6,000 and 7,000. The branch angles of the fruiting branches on the branches are as follows: For the erect tree species, the main branch retains the horizontal branches and oblique upper branches, and the upper part can properly retain some back branches, especially the juvenile trees of the erect type, and can leave more horizontal branches and The lower branches are branched and remain until the tip; for the open type, the upper part mainly retains the oblique upper branches, and the upper part can properly retain some horizontal branches. Resulting branch update: During the winter shear, the resulting mother branch should be retracted to the robust branch of the base. This method is called single branch update. If there are no renewed shoots available on some shoots, new fruit shoots drawn from the stems near the base of the resulting shoots can be replaced, and the original fruit shoots can be removed from the base. Several issues that should be noted 1 The planting density of peach trees must be reasonable. Generally, the plant spacing should be 2 to 2.5 meters and 3 to 4 meters; 2 After the pruning method of peach trees is performed slowly, the amount of flower buds left is relatively increased. Therefore, timely adjustment of tree load by manual sparse flowering and fruit thinning is a prerequisite for obtaining high quality and high yield; 3For weak trees and trees that cannot guarantee continuous updating of branches, it is necessary to strengthen water and fertilizer management, reduce load, etc. Restoring the tree vigor; 4 The large sawing left by the winter shear shall be promptly smeared with the protective seal of odd star healing agent. (Huang Qiming) Peach tree winter cuts are mainly short cuts Special interview with the reporter: Gao Dongsheng, professor of horticulture at Shandong Agricultural University Intern reporter Ding Yifeng Recently, on the question of winter shears of peach trees, the reporter interviewed Gao Dongsheng, a professor at the College of Horticulture, Shandong Agricultural University. A short cut and high Dongsheng told reporters that Tao Shudong's winter cut should pay attention to short cuts. The short cuts are mainly based on long fruiting fruit varieties. Long fruiting branches usually do not produce fruit at the top, and many flower buds in the middle result, so cut off the ineffectual part of the top and cut about 1/3 of the length. Among them, the long fruit branch with weaker growth should be short and heavy; the growing fruit should be strong and the long fruit branch with the upper part of the flower bud should be light and short. If the long fruit branch retains oblique or horizontal state, erect branches or pendulous branches should be removed; old trees are left with some upright branches; middle and short branches are not short cut except for dense cutting. In order to cultivate new shoots, branches that grow stably upright, have good lighting conditions, and develop at the apex of lateral branches can be cut short by about 15 cm for renewal shoot culture. For the long branches that have become senescent for many years, they are retracted and renewed, allowing them to re-grow the growing branches and then forming the middle and short fruit branches. Shuzhi Gao Dongsheng said that the general object of thinning is saplings and trees. Among them, young trees mainly cut off drooping branches, thin and weak branches, competing branches and leggy branches, and can also use secondary branches to expand the crown or promote its transformation into a result branch. The canopy of the adult result tree has been shaped, and a combination of shortening and sparse cutting may be adopted. The densely cut branches, thin and weak branches, overlapped branches, diseased and broken branches, straight branches and leggy branches are mainly sparsely cut.
