Description

Simple and easy rice seedling culture apparatus in laboratory

Technical Field

The utility model relates to a plant seedling cultivates technical field, especially a simple and easy rice seedling culture apparatus in laboratory.

Background

Adversity stress is always an important factor for limiting the growth and development of plants, and research on the adversity stress of plants is always a hot difficulty in plant research. In the laboratory, scientists usually identify the stress resistance of rice at the seedling stage by a hydroponic method. At present, the common rice seedling culture method in the test for identifying the salt tolerance of rice seedling stage is as follows: (1) the method for culturing seedlings by using the screen comprises the following steps: firstly, rice seeds are placed on a screen mesh fixed in an open container such as a turnover box, and then a proper amount of culture solution is added for culture; (2) the method for culturing seedlings by using the PCR plate comprises the following steps: firstly, rice seeds are placed in a transparent PCR plate, and then a proper amount of culture solution is added into an open container such as a turnover box and the like to enable the rice seeds to float on the liquid surface for culture. There are limitations to the two approaches described above. The method for culturing seedlings by utilizing the screen has the advantages that the screen is fixed, so that troubles are brought to seed placement, culture solution supplement or replacement and the like; in addition, there is no space on the screen, and it is not possible to screen various kinds of salt resistance. The method for culturing seedlings by using the PCR plate is easy to cause that certain slender seeds can not be fixed on the PCR plate if different varieties of seeds with great size difference are placed on the PCR plate with consistent aperture size.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a simple and easy rice seedling culture apparatus in laboratory, this simple and easy rice seedling culture apparatus in laboratory not only simple structure, preparation are convenient, with low costs, are applicable to the cultivation when many varieties moreover.

For solving the technical problem, the utility model relates to a simple and easy rice seedling culture apparatus in laboratory, including water planting case, culture plate and gauze, the water planting case is open hollow structure's in top turnover case, is equipped with the culture solution in the water planting incasement, and the bottom surface of culture plate floats on the culture solution, be equipped with a plurality of cultivation holes on the culture plate, cultivate the hole and go up a mouthful diameter wide in end opening diameter, the gauze setting is on the bottom surface of culture plate.

The opening of the water culture box is covered with a plastic film.

The diameter of the upper opening of the culture hole is 1.2 to 1.3 times of the diameter of the lower opening.

The culture plate is a foam plate with the thickness of 1 cm.

The thickness of the plastic film is 0.01 mm.

In the simple rice seedling culture device in the laboratory, the water culture box is only composed of the water culture box, the culture plate and the gauze, and the water culture box is a turnover box, so that the materials are easy to obtain, the preparation is convenient, the structure is simple, and the experiment cost is greatly reduced; because the culture plate floats on the surface of the culture solution, the culture plate is beneficial to the contact of the root system and the culture solution and the observation of the growth condition of the root system, and the culture holes arranged on the culture plate are convenient for batch culture of rice seedlings of different varieties (or intermediate materials) at the same time.

FIG. 2 is a schematic sectional view of A-A in FIG. 1.

Detailed Description

The following describes in further detail embodiments of the present invention.

In fig. 1 and 2, a simple laboratory rice seedling culture device comprises a water culture box 1, a culture plate 3 and a gauze 6. The water culture box 1 is a turnover box with a hollow structure and an open top, and the culture solution 2 is filled in the water culture box 1. The bottom surface of the culture plate 3 floats on the culture solution 2, a plurality of culture holes 4 are arranged on the culture plate 3, the diameter of an upper opening 8 of each culture hole 4 is wider than that of a lower opening 7, and the gauze 6 is arranged on the bottom surface of the culture plate 3.

In order to reduce the water evaporation in the water culture process, the opening of the water culture box 1 is covered with a plastic film 5.

For the convenience of operation and the growth of seedlings, the diameter of the upper opening 8 of the culture hole 4 is 1.2 to 1.3 times of that of the lower opening 7.

In order to improve the buoyancy, facilitate the production and facilitate the growth of the seedlings, the culture plate 3 is a foam plate with the thickness of 1 cm.

In order to reduce the cost and facilitate the operation, the thickness of the plastic film 5 is 0.01 mm, and the plastic film 5 can be a commercially available household preservative film.

In the simple rice seedling culture device in the laboratory, only the water culture box 1, the culture plate 3 and the gauze 6 form, and the water culture box 1 is a turnover box, so that materials are easy to obtain, the preparation is convenient, the structure is simple, and the experiment cost is greatly reduced. Because the culture plate 3 floats on the surface of the culture solution 2, the contact between the root system and the culture solution is facilitated, the observation of the growth condition of the root system is facilitated, and the culture holes arranged on the culture plate 3 facilitate the batch culture of rice seedlings of different varieties (or intermediate materials) simultaneously.
