Description

Culture apparatus for submerged plant seed germination experiments

Technical Field

The utility model relates to a laboratory equipment technical field specifically is a submerged plant seed sprouts experimental culture apparatus.

Background

At present, the relevant experimental apparatus that plant seed germinates is mostly the design of terrestrial plant seed, has the seed to germinate the case, germinate the bag, germinate the box etc.. These experimental devices can let the seed germinate under suitable conditions to have the space that makes root system grow downwards and stem leaf grow upwards. Plant roots are generally soaked in culture solution or rooted in soil and other matrixes, and plant stems and leaves are exposed in the air; due to the particularity of the growing environment of the submerged plant, when the germination of the seeds of the submerged plant is researched, the seeds of the submerged plant are mostly cultured by directly placing the seeds of the submerged plant in a water container or scattering the seeds of the submerged plant in the water container with the bottom paved with solid media such as quartz sand, soil and the like.

Because submerged plant grows in-process, its root, stem, leaf all submerge in the aquatic, the relevant experimental apparatus of current seed germination can't provide submerged plant's growing environment, if directly put submerged plant seed into aquatic and cultivate, can make the plant that has sprouted float in the water because of lacking the medium that can be used for root to fix. Although the submerged plant seed germination experimental device with the bottom paved with quartz sand or soil can better fix the germinated plants, the used materials may influence the growth of plant roots. In addition, in order to provide the growth space required by the submerged plant root system, the paved substrate is generally thick, the material cost is high, and the steps of elutriation and the like are time-consuming and labor-consuming.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

In the first embodiment, referring to fig. 1-2, a culture apparatus for submerged plant seed germination experiments comprises a culture cup 100, a clasp 200 and gauze 300,

the culture cup 100 is a transparent round table-shaped plastic cup with a big top and a small bottom,

the snap ring 200 is made of a plastic ribbon, and the diameter of the snap ring can be adjusted;

the gauze 300 is fixed in the culture cup through the clamping ring 200 and has a certain distance from the cup bottom;

wherein the culture cup 100 is made of hard plastic,

the snap ring 200 is a plastic tie of the prior art;

the mesh number of the gauze 300 is 50-500 meshes, and is determined according to actual requirements;

specifically, the extension of the gauze 300 is located above the snap ring 200,

in the second embodiment, referring to fig. 3-4, the difference between the first embodiment and the second embodiment is that the extension of the gauze 300 is located below the retainer ring 200;

referring to fig. 5 to 6, the third embodiment is different from the first and second embodiments in that the gauze 300 is wound and wrapped around the upper portion of the snap ring 200;

when in use, submerged plant seeds are placed on the gauze, a culture solution is poured into the culture cup, and the culture solution submerges the gauze 300; after the seeds germinate, the plant root system can penetrate through 300 gaps of the gauze due to geotropism and grow downwards, and the gauze can play a role in fixing the plants at the moment

In specific implementation, firstly, determining the distance between the fixed position of the gauze 300 in the culture cup 100 and the cup bottom, then adjusting the clamping ring 200 to a proper diameter, cutting the gauze with a proper size, placing the adjusted clamping ring 200 above the gauze 300, picking up the gauze wrapped with the clamping ring, placing the gauze in the culture cup, and downwards pushing the clamping ring by using a tool such as tweezers until the gauze 300 is tightly clamped by the outer wall of the clamping ring 200 and the cup wall of the culture cup 100; then, putting the treated submerged plant seeds, and adding nutrient solution or other solutions required by the experiment into the culture cup; the gauze 300 can be used as a carrier of submerged plant seeds, can also play a role in fixing the seedlings of the submerged plant after the seedlings germinate, and provides a space for the growth of the roots of the submerged plant because the gauze is fixed at a certain distance from the bottom of the cup. Use the device can conveniently observe the growth condition of submerged plant root system and stem leaf, if need measure growth index such as plant root length, stem length among the culture process, only need take out the gauze and can survey, in the reuse snap ring is fixed in the cultivation cup with the gauze after the survey is accomplished, it is less to the influence of plant. If the root system position growth space is not enough in the process of cultivateing, the distance of gauze fixed position apart from cultivateing the cup bottom can be increased to snap ring diameter through increaseing.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
