Method for preventing and controlling valsa canker and dry cracking of willows

Abstract

The invention discloses a method for preventing and controlling valsa canker and dry cracking of willows. The technical scheme comprises the following key points: 1) coating diluted lime powder or lime paste on trunks of the willows in summer; 2) coating diluted lime powder or lime paste on the trunks of the willows in winter too; 3) in the case of disease speckles, removing the disease speckles or infected barks by using a knife, and enabling a cut edge to be sloped; 4) washing and disinfecting wounds by using a bactericidal medicine; and 5) coating the wounds with diluted lime powder or limepaste. The method provided by the invention achieves the effect that the valsa canker and dry cracking of the willows can be effectively prevented and controlled.

Description

technical field [0001] The invention relates to the field of tree planting, in particular to a method for preventing and treating willow rot and dryness. Background technique [0002] Willow rot and dry cracking are easy to occur in northern areas. Long-term lesions can cause death and large-scale infection. The industry often uses fungicides (such as gentamicin) to remove the diseased bark and rinse and disinfect, but there is no effect or the effect is not obvious , In fact, the industry has overlooked some important details. Willow is a water-loving plant, and the storage or saturation of water in the tree is high. When encountering high temperature seasons and high temperature periods, direct sunlight exposure to water-saturated bark will cause burn damage, especially for tending forest willows. Most of them are young trees, and the bark is mostly without lignification, which is more prone to disease. In the high cold environment in winter, the bark is easy to frostbite....

[0002] Willow rot and dry cracking are easy to occur in northern areas. Long-term lesions can cause death and large-scale infection. The industry often uses fungicides (such as gentamicin) to remove the diseased bark and rinse and disinfect, but there is no effect or the effect is not obvious , In fact, the industry has overlooked some important details. Willow is a water-loving plant, and the storage or saturation of water in the tree is high. When encountering high temperature seasons and high temperature periods, direct sunlight exposure to water-saturated bark will cause burn damage, especially for tending forest willows. Most of them are young trees, and the bark is mostly without lignification, which is more prone to disease. In the high cold environment in winter, the bark is easy to frostbite. After the spring warms, the frostbite skin will slowly fall off or dry out. In fact, the bark is just like human skin, tender and moist. skin is easily damaged by sun exposure and wind chill
