Rapid regeneration method for kiwi trees with canker

Abstract

The invention discloses a rapid regeneration method for kiwi trees with canker. The method comprises the steps of 1, determining the kiwi trees suffering from the canker, and cutting off infected parts of the plants; conducting sterilization, seepage prevention and bandaging on the medulla, xylem and sections of the cut sections to completely prevent fluid of the kiwi trees from continuously flowing out; 3, conducting complete pest killing and sterilization on the plants; 4, supplementing nutrients for the diseased plants; 5, reserving new branches of the base part of the trunks, and conducting grafting in summer or winter of that year. According to the method, under the condition that the kiwi trees with the canker are not dug, the root systems, the tree fluid and the tree trunks can be effectively and well protected, new branches grow as soon as possible, the production recovery time is 1-2 years ahead of time, the production is recovered in time, garden destruction or garden reconstruction in different places after the canker occurs is avoided, and therefore the method can be used for treating and controlling the kiwi canker quickly, effectively and timely.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a rapid regeneration method for kiwifruit canker diseased trees. Background technique [0002] Kiwi fruit is an emerging fruit in the world, and it is an important industry in Sichuan, Shaanxi and other provinces in western China. In recent years, the global spread of kiwifruit canker is a fatal blow to the development of the industry. Kiwifruit canker disease is a condition that mainly manifests as kiwifruit plant trunk ulceration, epidermal water and pus, dry branches, and severe cases of single plant death, multi-plant death, death in patches, and large-scale death in the entire park. [0003] 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 kiwi...

AI Technical Summary

Problems solved by technology

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 cases, the branches dry up and reduce production; in severe cases, the trees die, and even the garden is destroyed.

[0004] For more than 30 years, international and domestic experts and scholars have carried out research and prevention based on the vision of bacterial causes of ulcer disease. The result is that the progress is slow, the scale of ulcer disease is getting bigger and bigger, and various prevention and control measures are basically ineffective.

[0009] 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, generally there are more than ten reasons for the formation, and there are many corresponding prevention and treatment methods, we need to start from these One by one to deal with, to implement, to avoid, in fact, basically impossible

[0012] 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.
