In order to improve the early benefit of modern orchards, the planting density is generally high in the young tree period, but this density needs to be adjusted with the expansion of the crown. The basis of adjustment is the transfer rate of branches between plants, and the method is to gradually thinning in stages and batches. From the perspective of orchard circulation, it is a variable density structure of first density and then sparse. Trees that are thinned halfway are called temporary plants, and those that have been preserved are called permanent plants. Therefore, the dense planting garden should first design permanent plants and temporary plants according to the varieties and work out different pruning schemes. Generally, temporary trees aim at early fruiting and high yield, and the whole tree can be regarded as a large fruiting branch group. When pruning, we should try our best to use various measures to promote flowers, so that all branches can bear fruit as soon as possible, and it is not required to cultivate any backbone branches and shape them into any tree.

Permanent plants, on the other hand, want to blossom and bear fruit as soon as possible, but the main task of bearing fruit is in the middle and late stage, so when pruning, we should cultivate all kinds of backbone branches according to the target tree, and ask other non-backbone branches to blossom and bear fruit as soon as possible on the premise of ensuring the growth and formation of backbone branches as soon as possible, so as to improve the early yield. So for an orchard, permanent plants and temporary plants are actually equivalent to the relationship between the main branches and fruiting branches of a tree. Permanent plants are mainly long trees, while temporary plants are mainly fruit-bearing. Temporary plants should make way for permanent plants in the growing space.

When the branches of two plants cross, the temporary plants should be retracted to ensure the continuous expansion of the permanent plants. The period and frequency of temporary cutting should be determined according to the planting density and crown development speed. Generally, thinning should be done every 3 to 5 years after five years of planting. In this way, temporary trees are gradually controlled, retracted and thinned in stages, which is conducive to making full use of land and light energy and steadily increasing orchard output. In order to give priority to the work path, the temporary trees between permanent trees should be thinned first, and then the temporary trees between permanent trees should be thinned.

The adjustment method of planting mode and row direction can be determined according to orchard topography, crown shaping mode and permanent plant configuration. There is no unified model, and the principle is to facilitate various management operations of orchards and ventilation and light transmission of crown.
