1. Pruning can control the yield of fruit trees and improve fruit quality. ?

2. Proper application of trees modeling pruning in gardens can show good artistic effect.

3. The crown expands with the growth of tree age, and there are too many branches and leaves, which will inevitably lead to the outer density and premature aging of the tree. Pruning can make trees live longer.

Function:

1, adjust the reasonable distribution of branches and leaves. That is, on the basis of reshaping, the density, distribution direction and leaf area coefficient of each part of the crown are adjusted to maximize the effective photosynthetic area of the crown.

2. Adjust growth and results. Make nutrition grow normally but not too much; Moderate flowering and fruiting without weakening the tree; At the same time, it can prevent fruit trees from aging ahead of time and renew and rejuvenate in time.

3. Adjust the proportion of branches. Different tree species and tree ages need to have corresponding and appropriate branch proportions, so that the operation, distribution, consumption and accumulation of nutrients in a year's growth cycle can be coordinated according to the normal growth and reproduction rhythm.

4. Pruning can also balance the growth potential between plants in the population and between the main branches of plants, thus achieving balanced yield and easy management. In addition, pruning is also a means to coordinate the growth of shoot and root system.

Extended data

Pruning method:

1, lion tail pruning method: too many internal branches are removed from the mother branch, resulting in the whole branch base being exposed, like a lion's tail. Lion tail pruning is an unacceptable pruning method, and it is forbidden to use it when pruning garden trees.

2. Thinning and pruning: mainly to reduce the density of living branches and make the distribution of mother branches and side branches of plants more uniform. The location and quantity of pruning should be determined in advance, and 25% of the crown should be pruned at most in a growing season.

3. Retraction pruning method: cut off a growing or annual twig, leaving the original bud; In order to achieve the established structural goal, the older branches are cut off and become short branches.
