Effective treatment method for kiwi fruit canker

Abstract

The invention discloses an effective treatment method for the kiwi fruit canker. The method comprises the following steps that 1, the severely-diseased part is cut away; 2, an agent directly enters the phloem for absorption, and through up-down delivery, pathogenic bacteria are killed; 3, the agent is slowly supplied for a long time; 4, the pathogenic bacteria are insulated and prevented from spreading; 5, sunniness heating is used for inhibiting the pathogenic bacteria; 6, by wrapping wounds and conducting shading, healing of the wounds is accelerated. According to the effective treatment method for the kiwi fruit canker, based on the characteristics of low drug resistance to the kiwi fruit canker (the kiwi fruit canker cannot be treated mainly because of the concealing of the pathogenicbacteria, which causes the agent not to be in contact with the pathogenic bacteria), local infection and low tolerance of high temperature (inhibition is caused at 28 DEG C, and death is caused at 30DEG C), through diseased peel cutting, agent storage by an inner wrapping layer, agent reservation by an outer wrapping layer and agent injection, the situation is avoided that in the prior art, the agent cannot be supplied to the phloem for sterilization for a long time. The canker is effectively prevented and controlled, and a good treatment effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to an effective treatment method for kiwi fruit canker. Background technique [0002] Kiwi fruit (Actinidia chinensis Planch), also known as fox peach, vine pear, sheep peach, muzi, mao fruit, kiwi fruit, hemp vine fruit, etc., the fruit shape is generally oval, the appearance is greenish brown, and the skin is covered with thick hairs.

It is a fresh, tender, nutritious and delicious fruit. Actinidia is a dioecious large deciduous woody vine. The male plants are hairy and have small leaves, and the flowers of the male plants appear earlier in the female flowers; the female plants are less hairy or glabrous, and the flowers and leaves are larger tha...

Problems solved by technology

Because the disease is very hidden, there is no effective treatment at present, and it can only be prevented in advance. Once the disease occurs, the trees can only be cut down, otherwise it may lead to the destruction of the whole garden. At present, there are many treatment trials such as hanging bottle infusion, scraping and smearing, etc. The effect is not ideal, and it is even more likely to cause mutual infection until the dead tree

[0004] The invention patent with the patent application number CN201710169369.9 discloses a method for the prevention and treatment of canker disease that does not affect the yield of kiwi fruit. In the initial stage of the disease, the initial disease point of the kiwifruit canker is inspected; Step 2: the initial disease point of the kiwifruit canker is excisioned and treated with smearing of medicaments on the excised initial disease point, but the method of this patent only It is suitable for the early stage of the disease, but not suitable for more serious diseases. It can only be used as one of the basic treatment steps and cannot play a real preventive role.

[0005] The invention patent with the patent application number CN201710831023.0 discloses a method for the annual prevention and treatment of kiwifruit canker, including the prevention stage and the treatment stage; the prevention stage: improve the disease resistance of kiwifruit by making microbial fertilizer, spraying leaves, branches or Brushing traditional Chinese medicine preparations to kill pathogenic bacteria hidden in the phloem of kiwifruit trees; treatment stage: root irrigation, smearing, spraying fungicides and traditional Chinese medicines to repair ulcer wounds, but this method is complicated to implement, time-consuming and labor-intensive, early prevention The effect is not bad, but the diseased plants are not ideal. In addition, the early prevention technology of kiwifruit canker disease is relatively mature, and the later treatment is the current problem
