Problems solved by technology

As a scarce radish germplasm resource, if the seedlings with standard traits screened after harvesting the fleshy roots are infected with diseased spots or diseased during winter storage, there is no effective and feasible method to prevent and control them. This is very important for the collection and preservation of radish germplasm resources. is fatal

Embodiment 1

[0039] The selected variety in this example is Korean Baiyuchun, with characteristics of the variety: fleshy roots are long cylindrical, white skin and white flesh, fleshy roots have high water content, are easy to be infected, and have a high rate of plant death after infection.

[0040] The specific prevention methods are as follows:

[0041] (1) Go to Lao Ye

[0042] In the middle and late stages of the vegetative growth of radish, this example is the period from October 10 to 20 in Jinan, Shandong Province. It is selected to be carried out on a sunny day from 10 am to 15 pm, and the two times (the interval between the two times is 8 days) The old leaves of radish are removed, 4-6 pieces are removed each time (20-25% of the total number of leaves) to increase light permeability and reduce the chance of pathogen infection.

[0043] During the vegetative growth period of radish, the control of aboveground diseases is the same as conventional methods.

[0044] (2) Harvest

Embodiment 2

[0076] The selected variety in this example is Shandong Weixian Qing. The characteristics of the variety are as follows: fleshy roots are long cylindrical, green skin and emerald green flesh, fleshy roots have a slightly higher moisture content, fleshy roots are susceptible to disease in an environment with poor air permeability, and the mortality rate after infection is high. The specific prevention methods are as follows:

[0077] (1) Go to Lao Ye

[0078] In the middle and late stages of the vegetative growth of radish, this example is carried out during October 10-20 in Jinan, Shandong Province. It was selected to be carried out on a sunny day from 10 am to 15 pm, and the two times (the interval between the two times is 7 days) The old leaves of green radish are removed, and the number of 3-4 pieces (20-25% of the total leaves) is removed each time to increase light permeability and reduce the chance of pathogen infection.

[0079] During the vegetative growth period of radish, ...

Abstract

The invention discloses a method for preventing main diseases of fleshy roots of radish seed plants. The method is mainly used for preventing fungal diseases and fungal diseases. The method includes the steps that old leaves of radishes are picked off in twice in the middle and late vegetative growth period of the radishes, and moisture is controlled before harvesting; the harvested radish seed plants of which the diameter of epidermosis spots is equal to or smaller than 3 cm are selected to be treated, wherein infected parts are removed thoroughly, then mixed powder of thiophanate methyl and kocide 3000 is smeared to treat wounds twice, and the wounds are coated and covered with laminated adhesive after being dehydrated and air-dried; the radish seed plants are directly planted in a facility, or fleshy roots are planted in a field after the radish seed plants are stored for overwintering, wherein the roots are quickly dipped with a mixed agent C or D in planting. By means of the method, the problem of material loss caused when the fleshy roots are infected with main diseases in the vegetative growth period and the winter storage period of the radish seed plants is solved, it is guaranteed that seeds can be obtained, and the work of collecting and storing radish germplasm resources is completed.

Description

Technical field [0001] The invention belongs to the technical field of vegetable disease prevention and control, and specifically relates to a method for preventing and controlling main diseases (fungal diseases, bacterial diseases) of fleshy roots of radish seed plants. Background technique [0002] Radish is an important vegetable crop that originated in my country. The ecological environment in my country is complex and diverse, and the germplasm resources of radish are very rich. Although the country pays more and more attention to the protection of radish germplasm resources, with the promotion of high-quality radish hybrid varieties and the change of farmers’ planting habits, many excellent radish germplasm resources that have not been collected and preserved in time by breeders are gradually disappearing. Therefore, there is an urgent need to protect and utilize these radish resources. In the process of collection and preservation, the fleshy roots of radish are susceptib...
