What should I pay attention to when pruning fruit trees in winter?

Pruning of fruit trees can adjust the growth of fruit trees' nutrition, make the trees transparent, reduce the consumption of their own nutrition, and be beneficial to the flowering and fruiting of fruit trees in the coming year. Pruning fruit trees is very important, although it has great benefits. If the pruning is unreasonable during the pruning process, it may cause great harm to the fruit trees, and even make us lose the grain in the coming year. So paying attention to the pruning time can greatly improve our output. Under normal circumstances, the pruning time of fruit trees in northern China is from the middle and late months of1/kloc-0 to the end of1February. Pay attention to the following aspects during pruning.

First, the growth is different, and the pruning is different.

1. For fruit trees with strong tree potential, it is necessary to prune both ends of the tree in the middle of 1 1 month, which can delay the growth, help the fruit trees store nutrients and make the fruit trees sprout stronger next year.

2. Weak trees are usually pruned at the end of1February, which can promote nutrient backflow. Pay attention to temperature changes when pruning in1February.

Second, the form of pruning

1. Shortcut

Proper subtraction of annual branches can promote the germination of lateral buds.

retract

Cutting the perennial branches short can slow down the total growth of fruit trees and change the direction of branches.

Play longer.

Trim the dense branches and put some branches with less fruit.

draw bit

It is to control the growth of the whole tree by not reducing annual branches and letting them grow naturally.

5. Gently wipe the bud and comb.

It can improve the nutritional imbalance of fruit trees and reduce the damage of fruit trees. It is more conducive to growth in the coming year.
