an object of the utility model is to provide a sunflower ethyl methane sulfonate mutagenesis treatment and mutant sieving mechanism.
The utility model discloses by following technical scheme implement:
the utility model provides an ethyl methyl sulfonate mutagenesis of sunflower and mutant sieving mechanism, includes the screening box, the inside central authorities of screening box are fixed with a plurality of bracing piece, are provided with one row of cultivation casing of cultivateing the sunflower between every two adjacent bracing pieces, the top of screening box opens there is the slot, the screening box has the apron through the slot is pegged graft, even opening on the apron has a plurality of bar grooves just to cultivateing the casing, the lateral part of screening box is opened there is the sliding tray, sliding connection has the slider in the sliding tray, the slider middle part is fixed with the laser pen.
Preferably, the bottom of the screening box body is provided with a drawing and pulling collection box, and the outer end of the collection box is fixed with a handle.
Preferably, the lateral part of screening box is provided with the ejector pin, the both ends of ejector pin carry out the joint through L shape fixture block and fix.
Preferably, the side part of the culture shell is provided with a rubber clamping edge clamped on the support rod.
Preferably, the sliding groove is arranged at the upper part of the support rod by 30cm-40 cm.
The utility model has the advantages that: this practicality can high-efficient safety filter the sunflower, and not only the screening efficiency is high but also the screening accuracy is higher.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic perspective view of the structure of the present invention;
FIG. 2 is an enlarged view of a portion of the structure of FIG. 1;
fig. 3 is a schematic view of another state of the present invention.
In the figure: screening box 1, bracing piece 2, cultivate casing 3, rubber card limit 4, collecting box 5, handle 51, slot 6, apron 7, bar groove 8, ejector pin 9, L-shaped fixture block 10, sliding tray 11, slider 12, laser pen 13.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, fig. 2 and fig. 3, the utility model provides the following technical solutions: the utility model provides a sunflower ethyl methane sulfonate mutagenesis treatment and mutant sieving mechanism, includes screening box 1, the inside central authorities of screening box 1 are fixed with a plurality of bracing piece 2, are provided with one row of cultivation casing 3 of cultivateing the sunflower between every two adjacent bracing pieces 2, open at the top of screening box 1 has slot 6, screening box 1 pegs graft through slot 6 and has apron 7, even division has a plurality of bar grooves 8 just to cultivateing casing 3 on the apron 7, the lateral part of screening box 1 is opened has sliding tray 11, sliding connection has slider 12 in the sliding tray 11, slider 12 middle part is fixed with laser pen 13.
The bottom of the screening box body 1 is provided with a drawing and pulling collecting box 5, and the outer end of the collecting box 5 is fixed with a handle 51.
The lateral part of screening box 1 is provided with ejector pin 9, the both ends of ejector pin 9 carry out the joint through L shape fixture block 10 and fix.
The side part of the culture shell 3 is provided with a rubber clamping edge 4 clamped on the support rod 2.
The sliding groove 11 is arranged at the upper part of the supporting rod 2 by 30-40 cm.
The utility model discloses a theory of operation and use flow: firstly, planting sunflower seeds which are not subjected to ethyl methanesulfonate mutagen treatment in a row of culture shells 3 at the end part of the side surface, which is just opposite to a laser pen 13 of a screening box body 1, to form a control group, then placing the sunflower seeds which are subjected to ethyl methanesulfonate treatment into a plurality of culture shells 3 and placing the sunflower seeds on the rest support rods 2 to form a plurality of rows, and meanwhile, when the culture shells 3 which are not subjected to mutagenesis treatment are placed in the screening box body 1, arranging the sunflower seeds in a plurality of rows along the support rods 2 in the longitudinal direction by taking the culture shells 3 which are not subjected to mutagenesis treatment as a reference, and carrying out sunflower mutant screening after the sunflower seeds grow;
