Problems solved by technology

When the damage is serious, it will have a great impact on tomatoes and cause huge losses to vegetable production
Because the disease occurs and develops in the tomato pith, the control rate of conventional spraying, root irrigation and injection is very low, usually less than 50%, and it will still cause serious losses
There are no literature reports on the combined application of vegetable slings and tomato bacterial pith necrosis

Embodiment 1

[0021] Example 1 A method for preventing and treating bacterial pith necrosis of tomato. Tomatoes are cultivated in a solar greenhouse, the branches are pruned individually, and the vines are hung with a plastic hanging rope carrying Zhongshengmycin. The plastic sling is 180-200cm long and has a rated load of 5-7.5kg. The plastic sling is composed of three 1.2mm-diameter polytetrafluoroethylene-based porous nanoparticle composite round wires with a microporous structure intertwined in a three-strand braid. , Zhongshengmycin is adsorbed on the surface of polytetrafluoroethylene-based porous nanoparticle composite round wire with microporous structure.

[0022] The polytetrafluoroethylene-based porous nanoparticle composite round wire with a microporous structure contains polytetrafluoroethylene and porous nanoparticles with a microporous structure. First, the polytetrafluoroethylene and porous nanoparticles are kneaded in an extruder, and the The kneaded mixture was extruded as...

Embodiment 2

[0027] Embodiment 2 selects 600m 2 Tomatoes are grown in the solar greenhouse, and the variety is Zidali. Planting on August 10, wherein, half of the tomatoes were hanged by the method of the present invention, the specific technical scheme was the same as in Example 1, and the other half of the tomatoes were hung by conventional hanging ropes as a comparison.

[0028] Test results: The incidence rate of bacterial pith necrosis of tomato treated with hanging vine was 0 during the whole growth period, and the incidence rate of bacterial pith necrosis of tomato treated with control was 21.6%.

Embodiment 3

[0029] Embodiment 3 selects 800m 2 Tomatoes are grown in the solar greenhouse, and the varieties are selected. Planting on January 15th, wherein, half of the tomatoes were hanged by the method of the present invention, the specific technical scheme was the same as in Example 1, and the other half of the tomatoes were hung with conventional slings as a comparison.

[0030] Test results: The incidence rate of bacterial pith necrosis of tomato treated with hanging vine was 0 during the whole growth period, and the incidence rate of bacterial pith necrosis of tomato treated with control was 17.3%.

Abstract

The invention discloses a method for preventing and treating bacterial pith necrosis for tomatoes. The method comprises the following step of hanging vines with plastic hanging ropes carrying zhongshengmycin during tomato cultivation in sunlight greenhouses, wherein the length of the plastic hanging ropes is 180-200cm, each of the plastic hanging ropes is formed by mutually winding 3 strands of polytetrafluoroethylene based porous nano particle composite round wires with a micropore structure in the shape of 3 strands of braids, and the surfaces of the polytetrafluoroethylene based porous nano particle composite round wires are adsorbed with the zhongshengmycin. The organic combination of hanging tomato vines and preventing and controlling plant diseases in an environmental-friendly manner is realized, the effects of preventing and treating the bacterial pith necrosis for the tomatoes are significant, and the incidence rate of the bacterial pith necrosis in the whole growth period is 0.

Description

technical field [0001] The invention relates to a method for preventing and treating bacterial pith necrosis of tomato, belonging to the technical field of agricultural pest control. Background technique [0002] Bacterial pith necrosis is an important disease of tomato, which occurs all over the country. When the damage is serious, it will have a great impact on tomatoes and cause huge losses to vegetable production. Because the disease occurs and develops in the tomato pith, the control rate of conventional spraying, root irrigation and injection is very low, usually less than 50%, and it will still cause serious losses. [0003] Hanging vines with hanging ropes for vegetable cultivation in solar greenhouses is an indispensable management link. There is no literature report on the combined application of vegetable sling and tomato bacterial pith necrosis. Contents of the invention [0004] The technical problem to be solved in the present invention is to provide a met...
