Physical isolation method for preventing kiwi tree canker caused by scolytidae insects

Abstract

The invention discloses a physical isolation method for preventing kiwi tree canker caused by scolytidae insects. The method is a method for physically preventing the kiwi tree canker by isolating thescolytidae insects in a plane or vertical plane mode. The method at least comprises one or more of the following measures that a, the scolytidae insects are isolated on the vertical plane of the trunk of a kiwi tree; b, an insect repelling bag is hung on the trunk of the kiwi tree to repel the scolytidae insects; c, the scolytidae insects are isolated on the ground plane of the kiwi tree. According to the method, the main part, damaged by the scolytidae insects causing the kiwi tree canker most severely, of the kiwi tree is found, physical isolation and protection are conducted on the key part, and the method is a precise protection method. The method is simple, high in operability and capable of greatly reducing the cost, and the application of other various kiwi disease and insect pestprevention, control and treatment methods is not influenced.

Description

technical field [0001] The invention belongs to the field of kiwi fruit planting, aims at healthy kiwi fruit trees, and in particular relates to a physical isolation method for preventing bark beetles from causing kiwi fruit tree canker. Background technique [0002] People's understanding of kiwifruit canker is based on the understanding of bacterial diseases. The relevant literatures about kiwifruit canker at home and abroad are basically described as follows: kiwifruit canker is a devastating bacterial disease that seriously threatens kiwifruit production; after the canker occurs, it is fierce and harmful, causing great losses to production. In the lighter case, the branches dry up and reduce production, in the severe case, the tree dies, and even the garden is destroyed. [0003] Canker disease prevention and control technology has failed to achieve major breakthroughs mainly due to the following problems: [0004] 1. It is believed that canker is difficult to control:...

[0005] 2. The prevention and treatment methods are general, uncertain, and the effect is not significant: because it is believed that the causes of kiwifruit canker are various, there are many corresponding prevention and treatment methods

[0008] 2. The occurrence of canker disease has nothing to do with the strength of the kiwifruit tree. Most of the strong plants that are 3 to 5 years old have more serious canker disease.

[0010] For more than 30 years, international and domestic experts and scholars have studied and prevented kiwifruit canker disease based on the vision of bacterial and destructive diseases. The research on its prevention, treatment and control has been slow and there has been no major breakthrough. The result is that kiwifruit canker The scale of the disease is getting bigger and bigger, and various prevention and treatment measures are basically ineffective
