Branch flow plasticity is a common physiological disease of peach trees, which is related to the growth of peach trees and the dangers of Tianniu. After the occurrence of plastic flow, the tree potential is severely weakened, and the backbone branches are often broken, resulting in incomplete canopy, premature tree failure, short-term results, low yield, and poor quality. Prevention and control measures: 1) In early spring, Taoyuan should strengthen drainage and drainage, prevent waterlogging, and pay attention to soil improvement. For example, if the soil is cultivated along a hillside, the acidity of the soil should be applied with lime; if it is planted on the viscous soil, organic fertilizers and phosphorus and potassium fertilizers should be added to promote the growth of peach trees. In addition, it is necessary to prevent and treat pests such as dried long-horned beetles in time, and to avoid the occurrence of wounds. 2) For trees that have been infected with gum, the twigs can be removed by trimming. The flow of glue on the branches should be scraped off and then sterilized with Bami 4-5 degrees lime sulfur at the wound and then protected with wax. Smear. In less rainy weather, it is also possible to use medical gentian violet to smear fluidic parts and wounds. The effect is more pronounced after 10 days of application.
