Problems solved by technology

The problem is that the water retention capacity of the paper bed is poor and needs to be replenished regularly
At the same time, the paper bed needs to be placed in a container such as a petri dish or a germination box. Due to the different sealing of the container, the speed of moisture volatilization in different paper beds is different, and it is difficult to ensure the consistency of water content in all germination beds.
In addition, the paper bed must be discarded after being used once and cannot be reused

Embodiment 1

[0017] Example 1 Preparation of superabsorbent resin germination bed

[0018] N 2 100 g deionized water, 35 g 2-acrylamido-2-methylpropanesulfonic acid, 12 g sodium hydroxide, 0.014 g potassium persulfate and 0.105 g N, N' -Methylenebisacrylamide was heated at 60°C for 12 hours, and the reaction product was dried at 60°C for 48 hours, pulverized and sieved (100 mesh) to obtain about 45 g of poly-2-acrylamido-2-methylpropanesulfonic acid powder. Take 0.02 g of poly-2-acrylamido-2-methylpropanesulfonic acid powder, add 20 ml of deionized water, stir evenly, pour it into a 9 cm petri dish, and let it stand for 24 hours to obtain a germinated superabsorbent resin with a thickness of 0.3 cm. bed.

Embodiment 2

[0019] Example 2 Seed germination test

[0020] Take 100 safflower dajinyuan seeds, repeat 4 times, and evenly place them in the 9 cm petri dish prepared in Example 1 containing the superabsorbent resin after water absorption. Another 100 safflower dajinyuan seeds were taken, repeated 4 times, and evenly placed in a 9 cm petri dish with two layers of wet filter paper as a control (CK). Then germinate in a light incubator at 30 °C during the day (8 h) and at 20 °C (16 h) at night for 16 days. Add 1 ml of deionized water to the paper bed culture dish every day to keep the filter paper moist, and the superabsorbent resin germination bed will no longer replenish water. Record the number of germinated seeds every day, and calculate the germination rate, germination index (GI) and vitality index (VI) on the 16th day. The calculation formula is: GI=∑(Gt / Dt), VI=S×GI, where: Gt is the tth The number of germinated seeds per day, Dt is the number of days of germination, and S is the...

Embodiment 3

[0021] Example 3 Seed germination test

[0022] Repeat embodiment 2, have the following difference: the safflower dajinyuan seed is changed into MS K326 seed.

Abstract

The invention provides a preparation method for a novel tobacco seed germination bed. According to the method, high water absorption resin poly(2-acryloylamino-2-methylpropanesulfonic acid) (PAMPS) powder absorbs water in a culture dish to prepare the novel tobacco seed germination bed. The novel tobacco seed germination bed prepared by the method of the present invention has the following characteristics that: the bed shows the hydrogel state; the tobacco seeds can be directly placed on the gelatinous germination bed, the seeds directly absorb the water from the hydrogel during the whole germination process, such that the regular water supplement is not required; the germination bed of the present invention has good water retention property, such that the moisture does not easily volatile, and the uniform germination condition can be provided.

Description

technical field [0001] The invention relates to a technology for detecting germination of crop seeds, in particular to a method for preparing a novel tobacco seed germination bed which can be used repeatedly and does not require watering in the whole process. Background technique [0002] A germination test is a determination of the maximum germination potential of a seed lot under laboratory-specific environmental conditions. This enables the quality of different seed lots to be compared. Field seeding values ​​can also be estimated. If the seed management department does a good job of germination experiments, it can promptly crack down on the production and operation of fake and inferior seeds. It is of great significance to ensure the safety of agricultural production, and also plays an important role in regulating seed quality disputes. [0003] Seed germination tests require specific germination beds. At present, paper beds (germination paper, filter paper, etc.) are...
