Fruit tree wounds generally include cuts, saws, sickles, and other human factors that cause destruction of the epidermis and cortex, and breakdown and exposure of the xylem.
Most producers do not pay attention to the protection of wounds, while a few only protect large cuts and rots. There are three hazards. First, wounds are prone to infective diseases such as apple rot, apple dry rot, and peach trees. Flow gum disease and so on. According to the survey, more than 90% of rot disease is infected from the wound. Second, the wound loses a lot of water, especially in the relatively weak period of tree activity in winter and spring, the wound does not heal, plus cold and dry, the water loss time is long, the speed is fast, and the damage is greater, which can cause the tree to be weak and resist disease. The resilience weakened and the quality of fruit production was affected. Third, the wound blocked the communication between nutrients, because the cortex is the main channel for transporting organic nutrients. With the wounds and the inability to heal in time, the root system loses nutrients and the tree is naturally debilitated. The main branch grows weaker, and the lightness of the small skin is poor. This is the reason. Therefore, fruit tree wound protection must arouse the attention of the majority of farmers.
According to three orchards in Sheshan Town, Zhaoyuan City, Shandong Province, the fruit trees were tested on apple trees for five consecutive years. All the trees were cut, sawed, and rot infected, and immediately after cutting, sawing, and scraping. Fruit tree wound healing agent, it has both bactericidal effect, but also can form a protective film on the wound, prevent disease and water retention, but also promote healing, the investigation found that the incidence of wound rot disease is less than one thousandth, the rate of diseased plant 5% However, the control was more than ten thousandths and seventy percent respectively, and the difference was extremely significant. The annual healing rate of rot diseased lice was more than two times that of the control, and the yield, yield, and fruit quality of the trees were significantly improved. The use of attention, first with the application of the wound with the application, so as not to take a long time to run the wound to run water infections; Second, apply evenly, so that the formation of a thick layer of the wound and uniform film, closed tight, to prevent the coating without close.
