Fruit tree bonsai highlights ornamental value, and fruit tree dwarfing technology is very important. Four artificial dwarfing techniques can help you create a potted "cash cow". 1, torsion branching method
In mid-May, one hand fixed the base of the trunk, and the other hand grabbed the upper end of the trunk and rotated it 360 degrees, then let go.
2. Binding method
After the full flowering period, tie a circle of iron wire every 3 cm away from the base of the trunk, ***3-4 times (spiral winding method can also be used), requiring that the iron wire should be tightened with pliers and inserted into the cortex, but it should not hurt the xylem. Pull out the wire in mid-August. Similar methods include "multi-cutting method" and "peeling method".
3. Rooting method
When potted fruit trees, the main roots of the fruit trees can be cut off, leaving 4-5 lateral roots, and the root neck of the fruit trees is higher than the basin edge 10 cm, and then all the roots are buried in the soil, and irrigation ditches are left at the basin edge or drip irrigation is carried out with an infusion set. After 1 year cultivation, all the soil above the basin edge is dug up, so that part of the root system of the fruit tree is exposed to the air, the root system is thickened, and the growth of branches is controlled to achieve the purpose of dwarfing. Moreover, this shape is unique, and the ornamental value is extremely high after the result comes out.
4. Chemical control dwarfing technology
During the growth period of fruit bonsai, plant growth retardants (such as paclobutrazol and B9 chlormequat) should be sprayed. Spraying leaves for 2-3 times can make branches stout, internodes shorter and plants shorter.
In addition to dwarfing, the following measures should be taken: 1, tree selection.
The branches of fruit trees are very plastic, so you can use your imagination to shape different trees according to your hobbies and the growth characteristics of cultivated tree species. For example, round head, tower, double-branched antler, single-branched cliff, dragon bend and so on. It is not only beneficial to the result, but also has aesthetic appreciation value.
2, control the crown pruning
Crown control technology plays a key role in the success or failure of fruit tree bonsai cultivation. In summer, it is necessary to pick the core, wipe the bud, pull the branch and twist the tip in time, coordinate the nutrient supply between branches and fruits, and promote the differentiation of flower buds. In addition, the techniques of ring cutting, bud smearing, core picking and branch pulling were applied to promote the growth of early fruits and flowers, and the techniques of appropriately increasing load and retracting were used to control the crown. Through the angles of open branches and sparse branches, dense branches and invalid branches, the illumination is enhanced and the ideal tree shape is obtained. After the grafting survives and grows normally, in order to enhance the aging resistance of bonsai, several curves can be carved on the trunk with a grafting knife. In the growing season, iron wire can be wound around the branches of fruit trees to fix the required tree shape.
Mastering the above technology will have a foundation for success, and more practice is needed to master the essence of technology. If you are interested, you can plant a few fruit trees at home and cultivate your favorite fruit tree bonsai. Maybe you can make a fortune!
