The first principle: tangible immortality, intangible chaos. The so-called tangible immortality means that in the process of fruit tree pruning, we should master the tree shape flexibly according to the actual situation, and we can't mechanically apply the pruning theory, dead buckle size and mechanical shaping. The so-called invisible disorder means that when the tree body is handled flexibly according to the actual situation of the tree, the crown must meet the basic requirements of the tree body structure of the fruit tree, and the branches and leaves should not be confused.
The second principle: Because trees are pruned, shape them with branches. The so-called pruning by trees means to consider the whole fruit tree as a whole, that is, to consider the tree species, variety characteristics, age and potential of fruit trees, as well as the balance between growth and fruit, and to determine the pruning method and degree that should be taken from the overall perspective, so that local pruning measures can play their due role. The so-called pruning with branches is based on the local analysis of fruit trees, that is, according to the local growth, branch number, branch type, angle, orientation and the number of flowers and fruits. Local shaping and pruning should be carried out under the guidance of overall judgment, and the relationship between local treatment and the whole should be considered.
The third principle: give priority to light cutting and combine light and heavy. The so-called light cutting means that the proportion of branch weight to the total weight of trees is very low. The so-called combination of light and heavy means that on the basis of lightly pruning the whole tree and increasing the total growth, some parts are controlled according to the needs of plastic surgery results to promote flowering and fruiting.
Generally speaking, it is necessary to observe the fruit trees in different growth periods, make some appropriate real-time adjustments to the growth of fruit trees, and carry out pruning and shaping so as not to affect their growth and development and fruit hanging. When pruning, give priority to with light, light and light combination; Overall consideration, combining long and short; Because trees are pruned, they are shaped with branches. "Master the above pruning principles, how to cut will not be a problem.
