Description

Technical Field

[0001] The utility model relates to the field of watermelon seedling cultivation, and specifically relates to a disease resistance screening platform for triploid watermelons. Background Technique

[0002] A triploid watermelon refers to a watermelon variety with three sets of chromosome groups in the watermelon; a normal watermelon is diploid, that is, the cells contain two sets of chromosomes; while triploid watermelons are artificially induced and cultivated; during the cultivation process, drugs such as colchicine are usually used to treat the seedlings of diploid watermelons to double their chromosomes and form tetraploid plants; then the tetraploid watermelon is used as the female parent and crossed with the diploid watermelon as the male parent to obtain the seeds of triploid watermelons; due to the imbalance of the chromosome groups, triploid watermelons will show disorders during meiosis, making it difficult to form normal gametes, and thus unable to fertilize and form seeds. Therefore, triploid watermelons are generally seedless and more convenient to eat.

[0003] When triploid watermelon seedlings are cultivated without disease resistance screening, it is difficult to evaluate and prevent diseases in the early stage: since disease resistance screening cannot be carried out at the seedling stage, it is impossible to know in advance which seedlings have better disease resistance and impossible to cultivate and promote them targeted; this may lead to the discovery of poor disease resistance in some plants only when diseases break out during the planting process, resulting in serious losses. Content of the Utility Model

[0004] The purpose of the utility model is to provide a disease resistance screening platform for triploid watermelons to solve the defects mentioned in the above background technique.

[0005] To achieve the above purpose, a disease resistance screening platform for triploid watermelons is provided, including a screening table. A plurality of groups of ventilation holes are evenly opened on both sides of the bottom of the screening table, and a seedling screening frame is installed inside the screening table. At the same time, a plurality of groups of nurturing grooves are evenly opened on the surface of the seedling screening frame, and the distance between adjacent two nurturing grooves is the same. The surface of the seedling screening frame is covered with an upper cover, and an air vent tube is fixedly installed at the middle position of the surface of the upper cover. At the same time, the air vent tube and the sealing cover are of suitable sizes, and the cross-section of the sealing cover is set in a "U" shape. The bottom of the sealing cover is inserted outside the air vent tube; both the sealing cover and the air vent tube are circularly arranged.

[0006] Preferably, the whole screening table is made of plastic and is a rectangular structure, and the ventilation holes on both sides of the screening table are communicated with the bottom holes opened at the bottom of the nurturing grooves.

[0007] Preferably, the nurturing groove is a regular hexagon structure, and different varieties of triploid watermelon seedlings are planted inside a plurality of groups of nurturing grooves. At the same time, the depth of the nurturing groove is 6 cm.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Please refer to Figures 1-4, the present utility model provides a disease resistance screening platform for triploid watermelons, including a screening table 1. A plurality of groups of ventilation holes 2 are evenly opened on both sides of the bottom of the screening table 1. A seedling screening frame 5 is installed inside the screening table 1. At the same time, a plurality of groups of breeding grooves 51 are evenly opened on the surface of the seedling screening frame 5, and the distance between adjacent two groups of breeding grooves 51 is the same. The surface of the seedling screening frame 5 is covered with an upper cover 3, and an air vent tube 7 is fixedly installed at the middle position of the surface of the upper cover 3. At the same time, the air vent tube 7 and the sealing cover 6 are of suitable sizes, and the cross-section of the sealing cover 6 is set in a "U" shape. The bottom of the sealing cover 6 is inserted outside the air vent tube 7; both the sealing cover 6 and the air vent tube 7 are circularly arranged.

[0018] Working principle: When in use, the main method for screening the disease resistance of triploid watermelons is as follows: Different triploid watermelon plants are respectively planted in a plurality of groups of breeding grooves 51 on the surface of the seedling screening frame 5, and high marks are made. The plants are exposed to the disease environment, or by the method of artificial inoculation of pathogenic bacteria, so that the watermelon plants planted in the breeding grooves 51 are infected with the bacteria; Observe their disease occurrence conditions; During the observation process, a series of indicators will be recorded to evaluate the disease resistance, such as the time of disease occurrence, the severity of the disease, the size and quantity of the disease spots, etc.; For example, if it is found during the screening process that some triploid watermelon varieties start to show symptoms one week after inoculation with pathogenic bacteria, and the disease spots are small and the disease develops slowly, while some other varieties show severe symptoms three days after inoculation, then it can be considered that the former has stronger disease resistance; Finally, according to the observed and recorded data, different triploid watermelons are compared and analyzed to screen out those plants or varieties with strong disease resistance, so as to give priority to their use in subsequent planting and promotion; It can be convenient for farmers. During the large-scale planting of watermelon seedlings, it is only found that some plants have poor disease resistance when the disease breaks out, reducing the losses of melon farmers.
