Sloping-bottom type seed germination box

Abstract

The invention discloses a sloping-bottom type seed germination box which is composed of a transparent box body, a transparent box cover, supporting feet, an air hole and an overflow hole. The supporting feet are located on the lower surface of the box bottom and put up one end of the box body to make the bottom face of the seed germination box have an included angle to the horizontal plane; the overflow hole is formed in the lower portion of the box wall at the low end of the box body and has a certain distance from the box bottom, and the box wall and the box bottom which are below the height of the overflow hole together form a reservoir in the seed germination box; the air hole is formed in the box cover. The sloping-bottom type seed germination box is simple in structure and convenient to use. Seed germination experiments are conducted by using the sloping-bottom type seed germination box, times of adding water can be reduced, germinating beds can be kept in a moist state all the time, influence on the seed germination due to too much water or too little water can be prevented, directional growth of seed roots can be achieved, and determination can be conducted on characters such as root length conveniently.

Description

Technical field: [0001] The utility model relates to a seed germination box with an inclined bottom, which relates to a device for a seed germination test, in particular to a seed germination box with an inclined bottom used in the seed germination test. Background technique: [0002] The existing germination box has a flat bottom, and one or more layers of moist absorbent paper are used as the germination bed for germination on the paper. The absorbent paper is placed in the germination box, and the seeds are placed on the paper. The paper bed material is easy to obtain, easy to operate, and can observe the germination of seeds every day. However, the water holding capacity of the paper bed is small, which cannot meet the needs of wheat and other medium-sized seeds for imbibition and seed germination, and water must be artificially replenished every day. Due to differences in the moisturizing properties of different germination boxes, the amount of water required for each ...

Problems solved by technology

[0007] The above two patents can keep the germination bed in a wet state, and can realize no water addition or reduce the number of water additions during the germination test, but when the former is used, the two ends of the length of the absorbent paper must be symmetrically folded towards the bottom wall, which is harmful to a large number of people. For the germination test of samples, its operation requirements are relatively high; and the latter has the defects of not easy to obtain materials, difficult to sterilize and inconvenient test operation; in addition, because the germination beds of the two are flat, the seed roots cross each other, which is used as a measure of seedling quality. The important index "root length" and its related traits are inconvenient to measure
