In the winter, the fruit trees will begin to be trimmed. This is one of the effective measures to maintain high and stable production of fruit trees. Some fruit trees use large saws to remove large branches and cause large kerfs. If the kerf is handled improperly, it must not be healed, and if it is severe, excision of fruit trees can be caused.
In order to find an effective way to treat kerfs, we performed a mud coating test on the rips of the fruit trees, which worked well. The specific method is as follows: After tree-shape transformation of the fruit trees in the winter or early spring each year, the kerfs are first cut with a guillotine at the place where the kerfs are large, and the xylem is flattened, lightened, and then sawn with a thin mud. Then use a plastic cloth to wrap the saw mouth to prevent rain or early cracking. It should be noted that the plastic cloth should be selected to have a flexible, durable product with a thickness of about 0.08 mm in order to prolong the healing time of the saw cut.
The investigation found that the healing rate of the smashed smashed mouth reached 100%, the average width of the callus was 8.8 mm, and there was no occurrence of fruit tree rot disease. The cost was only 0.2 yuan per square meter. With plastic cloth dressing the well sawed mouth, the muddy group still maintains a certain humidity, which can promote the healing of the sawdust. The mud coating has a good healing effect on the sawing of the fruit tree, which can effectively prevent sawdust from infecting the fruit tree rot, and is economically convenient. It is recommended to promote it in production.
