Embodiment 1

[0037] Experiment was carried out with 100 mu of kiwi fruit.

[0038] 1) Before the end of November, within 15 days after the winter construction is completed, apply dry fertilizer. According to the mass percentage, the dry fertilizer is composed of 10% plasma-treated vegetable oil and 90% polymer powder. The specific steps are: pour 500g of bagged dry fertilizer into a plastic container, add 350g of clear water, that is, mix it with clear water at a ratio of 10:7, slowly stir it into a paste mixture during the water addition process, and then spread the paste mixture evenly on the On the kiwi fruit branches, pay attention to the paste mixture should be mixed evenly until there are no lumps or lumps, and the thin state is the best if it can evenly adhere to the bark after smearing.

[0039] 2) Add 5ml of silicone to every 15kg of the result of step 1), and mix well;

[0040] 3) Spread the result of step 2) evenly on the central stem, main vine and all branches including b...

Embodiment 2

[0043] Experiment was carried out with 100 mu of kiwi fruit.

[0044] 1) In mid-February or at the germination stage, spray the whole garden once with 50% tuzet wettable powder 600-800 times and 10% imidacloprid 3500-4000 times, focusing on the bud eyes and branches;

[0045]2) 7-15 days before flowering, spray the whole garden once with 20% chlorfenapyr 600-800 times and 10% chlorfenapyr suspension 1000 times;

[0046] 3) In early August or after the rainy season, spray the whole garden with 800-1000 times of 45% disenium and 1000 times of 2.5% beta-cyhalothrin EC;

[0047] 4) After fruit picking, mix the water-soluble fertilizer and water at a weight ratio of 1:100-200, then add organic silicon at a ratio of 5ml / 15kg water, mix well, and spray the whole garden once, focusing on the leaves and ground; the water-soluble fertilizer is plasma-treated vegetable oil;

[0048] 5) In mid-December, after winter pruning, spray the whole garden once with 3°-5° lime sulfur mix...

Embodiment 3

[0051] Experiment was carried out with 100 mu of kiwi fruit.

[0052] 1) Within one month after fruit picking, apply bio-organic fertilizer 10-15kg / plant and root fertilizer 0.5-1.0kg / plant in the concentrated distribution area of ​​kiwifruit tree absorption roots, and then plow the fertilization area by more than 20cm; Fertilization, by mass percentage, consists of 1% plasma-treated vegetable oil, 90% aggregate powder and 9% water;

[0053] 2) In the early stage of the disease, mix the water-soluble fertilizer and water evenly at a weight ratio of 1:300-600, and then spray the soil surface of the whole garden; the water-soluble fertilizer is vegetable oil treated with plasma.

[0054] After the above soil improvement and root prevention and control, it was found after observing at intervals of 180 days that no canker occurred in the kiwifruit plants.

Abstract

The invention provides a three-dimensional prevention and treatment method of bacterial canker of kiwifruits. The method comprises the steps that stem coating is conducted on plants in winter, pesticide and bactericide killing is conducted in time, and soil is improved and sterilized. In the stem coating stage, stem coating fertilizer is used, and the stem coating fertilizer, by mass, comprises 10% of plant oil processed through plasma treatment and 90% of polymer powder; in the real-time pesticide and bactericide killing stage, 50% of 600-800-fold tuzet wetting powder, 10% of 3500-4000-fold imidacloprid, 20% of 600-800-fold buprofezin, 10% of 1000-fold chlorfenapyr suspension liquid, 45% of 800-1000-fold ambam, 2.5% of 1000-fold efficient cyhalothrinmissible oil and water soluble fertilizer are adopted, and the water soluble fertilizer is plant oil processed through plasma treatment; in the soil modification stage, root fertilizer is adopted, and the root fertilizer, by mass, is composed of 1% of plant oil processed through plasma treatment, 90% of polymer powder and 9% of water. The three-dimensional prevention and treatment method has a remarkable bacterial canker prevention effect, and effectively prevents secondary damage and pathogen infection.

Description

technical field [0001] The invention belongs to the field of prevention and treatment of fruit tree canker, and in particular relates to a method for preventing and treating kiwifruit canker. Background technique [0002] Plant cankers are mostly caused by fungi parasitic on the leaves, stem cortex or branches of plants. This fungus is the pathogen of many broad-leaved trees or shrubs. After the canker fungus infects the plants, the symptoms of ulcers often do not appear immediately, which is a latent infection. When the tree loses water or its growth potential declines, it develops into canker spots. If the treatment is not timely, the cankers will expand year after year, and even cause the stems and branches to break or die. [0003] Pseudomonas syringae pv. kiwifruit ( Pseudomonas syringae pv. actinidiae, Psa ) caused by kiwifruit canker is one of the most devastating bacterial diseases in production, and it is a quarantine disease in forestry in China. In addition to ...
