As soon as winter comes, fruit trees will start to prune. This is one of the effective measures to maintain the high and stable yield of fruit trees. Some fruit trees need to use big saws to remove large branches, resulting in large saws. If the sawing is not properly handled, it will not heal.

  In order to find an effective way to treat sawing, we carried out mud test on sawing place of fruit trees, and the effect was very good. The concrete methods are as follows: after the tree is reformed in winter or early spring every year, the sickle is used to flatten the cortex and xylem of the sawsaw and to apply the slime to the sawmill. Then use plastic cloth to wrap saws to prevent rain from washing or cracking. It should be noted that the plastic cloth should be elastic and durable, with a thickness of about 0.08 millimeters, so as to prolong the time of sawing.

  It was found that the rate of healing was 100%, the average width of callus was 8.8 mm, and no fruit rot disease occurred. The cost was only 0.2 yuan per square meter. Using plastic cloth to wrap the sawing mouth intact, the mud still maintains a certain humidity, which will make the saws continue to heal. It has good healing effect on sawing of fruit trees. It can effectively prevent sawing from infecting fruit rot disease, and is economical and convenient. It is recommended to be popularized in production.
