Fruit tree pruning principles and methods

The growth stage of fruit trees is divided into young trees, fruiting and aging, three different periods of fruit tree growth characteristics are not the same, so it is necessary to prune according to the growth characteristics of fruit trees.

1, young tree period: young tree pruning is to adjust the shape of the tree, expand the canopy of the fruit tree, increase the amount of branches of the fruit tree, so that the fruit tree better photosynthesis. Young tree period of reasonable pruning, in addition to improve the yield of fruit trees and fruit quality, but also can make the fruit tree early results.

2, fruiting season: fruiting season pruning is mainly sick branches, weak branches, draw new branches cut off, so that the tree can develop better, so that the growth and fruit trees to achieve a balance, to maintain a good structure of the tree, so as to make the tree's fruiting years longer.

3, senescence: senescence fruit tree absorption of nutrients become poor, so this period should be timely to affect the fruit tree nutrient absorption and photosynthesis of the branches cut off, so that the strong branch better absorption of nutrients, so that the fruit tree fruit to reach a higher level.

Commonly used pruning methods: centering, short pruning, thinning, taking branches.

1, centering is to remove the shoots of the branches, control the growth length of the branches, so that the fruit tree nutrition to achieve balance.

1, short pruning: part of the branches of the fruit tree will be cut off, so that the fruit tree nutrition better supply of strong branches, to reduce unnecessary nutrient consumption.

3, thinning: the diseased branches, dead branches, long branches cut off, so that the canopy within the ventilation and light better.

4, take the branch: will grow too strong branches with a hand gently pinch its internal bast and xylem, inhibit the growth direction of the branch and growth. To the fruit tree pruning every year, but also according to the different growth stages of fruit trees to prune, pruning principles for the light-based, light and heavy combination; integrated, long and short combination; tree pruning, with the branch for shape. When pruning and then according to the growth of fruit trees in different according to the actual situation to pruning can be.

After pruning, the proper application of water-soluble fertilizer, balanced tree nutrition.
