Seedlings cut out fine

In recent years, no one cares about the large-scale seedlings of some nurseries because the incorrect pruning habits lead to a poor tree. Therefore, pruning becomes a problem for seedling producers. "A boutique tree, a repudiation of a seedling", only the correct pruning can produce a fine product.

Pruning should be done as early as possible. The pruning and shaping should be done as early as possible before the seedlings are basically shaped. Such as Pinus bungeana, the seedlings grow very slowly and enter the fast growing period after 6 years of age. Therefore, pruning should be completed before the age of 6. For seedlings such as Pinus armandi, Pinus tabulaeformis, etc. that entered the relatively high growth period, the growth of seedlings should be considered as appropriate. Small seedlings are much easier to trim than larger seedlings. Even if there are some minor mistakes in the pruning process, they will be compensated for by the time the nursery stock is still in the nursery. As soon as possible, the seedlings that are pruned as early as possible reduce the pressure during the growth of the seedlings and after the seedlings are trimmed, and are beautifully dried.

In order to keep the seedlings from being pruned, the small and big ones should adhere to the principle of "little tips and big ones." Seedlings, strong vitality, fast growth, pruning intensity should be a little larger, can cut branches can not be cut off to avoid the second trim, both time-consuming and laborious, but also affect the tree shape; for large seedlings, we must be cautious, look at one step One step, you can cut or not to leave, to observe the aftereffect, wait for the opportunity to cut. During the pruning process, missed hands should be avoided as much as possible. Otherwise, there is no time for the seedlings to make up for pruning errors.

The site should be pruned for the pruning of the seedlings, the main purpose of which is to set the number of dry shoots - dry or dry. Therefore, it is sufficient to set the dry count according to the seedlings' own conditions. For large seedlings, tailor-made according to their natural conditions, can be a tree-shaped Zhou Zheng, it can be odd-shaped, but no matter what kind of tree, should remove the multiple branches, overlapping branches and weak branches of the roots. In addition, if there are conditions, during the growth of seedlings, pruning can be performed at any time with the changes in seedling height and seedling crown, in particular, the weak stems of multi-dry seedlings should be timely removed, and the tree shape and tree vigor should be avoided due to late drying. Have an adverse effect.

Heavy cutting to establish the shape of the crown for the special poor seedlings, whether it is evergreen or deciduous trees, through re-cut can be regained fresh. Evergreen trees are slower, while deciduous trees can basically meet the exit conditions within 3 years.

After the seedlings are trimmed, the big wounds can be smeared with paint. When there is no paint, the wounds can be sealed with yellow mud. To compensate for the sap loss, timely watering should be completed at the end of trimming.
