1, pruning time:
Pruning time of peach trees can be carried out in summer and winter, generally from May to July in summer, the first pruning in May, the second pruning in early June and the second pruning in early July. Winter usually lasts from the end of 165438+ 10 to the beginning of 65438+February.
2, young tree pruning:
Pruning of small trees usually begins after transplanting. The main purpose of pruning young trees is to enlarge the crown, and the selection methods are light pruning and short pruning. We need to trim the messy branches at the lower part of the small tree, leaving only some branches and leaves.
3. Pruning in the first fruit period:
Tree pruning at the initial fruit stage mainly refers to the pruning of peach trees at the beginning of fruiting in recent two years. At this time, the fruit of peach trees is still relatively small, so the main purpose of pruning is to reshape, facilitate the later harvest and improve the fruit setting rate of peach trees in the later period. Generally, the method of light cutting and long putting is adopted to slowly cultivate the fruiting branches.
4. Prune trees in full fruit:
Pruning of peach trees in full fruit period is also the most critical, which will affect the growth and fruit yield of peach trees. At this time, the pruning principle of peach trees is to remove the weak and retain the strong.
5, late growth pruning:
Pruning of peach trees in the later period is also a stage of slow senescence of peach trees. At this time, pruning is mainly about pruning old branches and re-cultivating new branches.
Function:
Pruning is an important technical measure for peach cultivation and management. The research on new pruning methods of peach trees in winter for the purpose of simplifying pruning techniques and achieving early fruit, high yield, stable yield and high quality has been highly valued by all countries in the world.
The reasonable transformation of peach tree structure and the application of long branch pruning technology can effectively improve the ventilation and light transmission conditions of peach garden, reduce the outward migration of fruit parts year by year, increase the illumination of peach tree cavity, improve fruit setting rate and yield, and improve fruit quality.
