The pruning time and season of pear trees are mainly to cut off branches that don't like fruit, otherwise it will absorb a lot of nutrients and affect fruit yield. Pruning time is generally in the growth period and dormancy period. Spring should be carried out in March-April, pruning some branches that don't like fruit. Pear trees can be pruned all year round, but the pruning points are different in different seasons. Do pear trees need pruning after flowering? If not pruned or lightly pruned in winter, pear trees can be pruned appropriately after flowering. When should pear trees be pruned before flowering? The main function is to reduce the number of etiquette as much as possible, so that the branches of fruit trees can bear reasonable fruits and adjust the load of fruit trees. What needs pruning at this time is usually pruning branches that are too light and spend too much in winter.
In fact, pruning pear trees is very simple, and it can be carried out according to the principles of removing strength and leaving weakness, removing straightness and leaving flatness, and removing straightness and leaving inclination. When pruning, cut off the useless branches on the tree, and sparse the dense branches. The pruning method of pear trees is to prune all kinds of useless branches first. In this way, sunlight can be saved for the fruit branches, which can be used to give the fruits more sunlight and sufficient illumination. The next step is to pull some dense branches to a larger plane, so that the crown of the tree can accept the sun more, and it is more convenient to pick without climbing very high.
Summer pruning is growing pruning. Because trees grow vigorously and are sensitive in the growth period, the general methods are wiping buds, removing buds and coring. Generally, pear trees can be pruned half a month before they germinate in spring after falling leaves in autumn. There are also slow release, throwing release or long release. At this time, the annual branches are not pruned, and the slow release can slow down the growth potential, and the young trees can bear fruit early and slow down the oblique branches.
How to bloom more when pruning pear trees? When pruning, you should start from the trunk and grade the branches, secondary branches and secondary branches layer by layer. The branches and leaves of the trunk are the strongest, and the branches and leaves to the lower level are getting weaker and weaker. The branches and leaves at the same level should have the same upward trend and the spacing should be reasonable to ensure that the sun can shine on the branches and leaves at each level from the top.
Overall pruning should play a role in controlling excessive growth of branches, promoting the growth of weaker branches and balancing the development of pear trees. The whole pear tree is shaped like an umbrella. Affected by light, it is easy to form a hollow middle and a strong growth state outside. How to prune pear trees? Pruning technology must be combined with management level, and the role of plastic pruning can be well reflected in well-managed pear orchards. Different cultivation modes need different methods of shaping and pruning, and the degree of pruning is also different.
For example, close planting garden needs smaller crown diameter and shorter crown diameter, while sparse planting garden needs larger crown diameter and larger crown diameter. In a word, as long as different shaping and pruning are carried out according to different situations, better results will be achieved.
