This preferred scheme guarantees the joint strength after the location of upper disc and lower disc through the setting of a plurality of reference columns and constant head tank, improves the intensity of shock resistance when wasing.

Preferably, the upper perforations are arranged in rows and columns. This preferred scheme is through last perforation and the setting of perforating regular arrangement down, and the seed of being convenient for is placed in order, also is convenient for mark and location to last perforation and perforation down, can also be according to seed quantity simultaneously, the fenestrate area under perforation on adjustable.

Preferably, the cross sections of the upper and lower through holes are rectangular. This preferred scheme has increased the space when seed water planting through the setting of rectangle, compares with circular.

Preferably, the positioning groove is formed in a lower reinforcing column with a triangular section, the reinforcing column is located at a corner corresponding to the lower through hole, and the positioning column is fixedly connected to an upper reinforcing column which is arranged corresponding to the lower reinforcing column.

This preferred scheme has strengthened the condition emergence that the constant head tank was seted up on the interval part between two adjacent lower perforation, caused the intensity reduction between two corresponding perforation in the time of having improved upper disc and lower disc intensity through the setting of strengthening the post.

Preferably, the filter screen is adhered to the upper disc and the lower disc, the wire diameter of the filter screen is smaller than 0.5mm, and the aperture length is 3-4mm. The preferred scheme is convenient to operate and convenient to replace the filter screen through the bonding arrangement; and simultaneously, the restriction of the screen diameter and the aperture of the filter screen is beneficial to the downward growth of the radicle of the seed.

The beneficial effects of the utility model are as follows: the seeds are placed in the lower perforation, the filter screen supports the seeds, and the hole walls of the adjacent lower perforation divide different seeds, so that the seeds are prevented from moving left and right, and the seeds are prevented from being mixed; the upper disc is covered on the lower disc through the positioning structure, the restriction of the movement of the seeds in the height direction is realized through the filter screen, and meanwhile, the cleaning liquid is convenient to enter the upper perforation and the lower perforation, so that the seeds are convenient to clean. After the cleaning is finished, the upper disc is taken down from the upper part of the lower disc, and seeds are directly left in the lower disc, so that the subsequent germination of the seeds is facilitated; meanwhile, after the upper tray is turned over, the filter screen can be used as a culture tray for water culture when the filter screen is positioned below the upper tray. When the water planting, through filter screen and last perforation, filter screen and lower fenestrate cooperation setting, directly with the seed place on the filter screen can, when sprouting to certain degree, only need change water planting liquid alright carry out a plurality of follow-up experiments such as saline and alkaline stress treatment, nutrient treatment, reduced the use of consumptive materials such as experiment time and culture dish. In addition, compare with current hydroponic device, use this hydroponic test dish need not put into the minor diameter round hole with the seed single grain after sprouting, avoided the root system damage to the influence of experimental result because of the operation causes, alleviateed the work load moreover, simplified the operation step of hydroponic experiment.
